ok..bit confused..P79 has round or square ports... im pretty sure they are round?? but ive been fooled before =)

THnx Paz........no owners manual in this one ofcourse=) so if anyone has one and can take a peek?? that would be awesome.. guess ill call OKC nissan monday, if i cant find it behind some kickpanel somewhere. so much for the "come on Paul.. it should be an easy drive and ill buy the food"..should have said beer.

Ok this might be an odd question, and when are they not =) but i was driving my Uncles 92 300zx and was coming from arkansas back to ok and went through some road construction.. bump ahead sign shoudl have read canyon ahead... once i realigned my spine and got my teeth seperated the car started sputtering and finally died and i coasted to a stop....wont start and after fiddling with it i realize ..No Gas. has 3/4 of a tank but its not getting fuel.. ok... after checking for loose anything under the hood and checking the fuel lines out back... fuel pump wires ..still nothing. i called my dad and got a flatbed to come pick us up.. now as i was talking to my dad on the way home he reminded me of something simliar that happened to his 96 ford crown vic.. he hit a huge pothole and same thing happend.. turned out teh crown vic has an emergency shut off incase of a wreck/rollover.. theres a lever in the trunk you pull to reset the circuit and your running again.. DOes the 300zx have something similiar that im overlooking?? any and all other suggestions are welcome but we have traced the fuel lines and nothing was broken and all the wires to the fuel pump are intact.. just havnt run a tester on them yet since im still on the way to texarcana with it on the flatbed.. thnx Paul

Ok it was an IC down low LOL thought i was seeing things =).. btw love the rear fender also TURBO FB ... btw, where did you get them and are they still available .. i really like that look for some reason but i photocrapped it to my 280zx and actually liked it better on that, go figure =0)

Awesome attention to the little things... very nice cars. BTW what seats are those in the red Z out of?? they look really nice.

better profile shot and i have to say i like it also.. its different. hmmm is that an intercooler buried really low in there???

i like the fact the gas cap is on the drivers side.... =) great drawings as usual

would really like to see a side shot of that.. i like the front view so far but really would like a diff profile and see how it was attached.. reminds me of that pic i saw floating around where someone split and narrowed the front end of a Ford Taurus to a 280.. odd looking but the work that went into it made it nice

any new pics or progress done ?? i really want to see this installed =)

well mostly narrowed down... =) he has the P-79 head from his original motor but put it on a stock 74 later 260z block... Yeah i thought it was an 81...but apperently the only thing left of the 81 in this car is the 5 speed and rear end... he removed all the efi stuff and put head and carbs on this one.. i couldnt find a block number partly because we didnt have a flash light and it was buried in his garage and also becuase he put airconditioning in it he made his own bracket and it covers where i think the block code is at =/, but it is the stock 74 1/2 260 block so hopefully that narrows it down with regards to flat top or dished pistons. and regards to properly tuned carbs.. he was nodding his head up and down in a vigourous fashion when i started talking about what a few people said about teh difficulty LOL he wishes he had stuck with his duals he had before becuase it took him so long to "tune" these.. they run fine but properly tuned... he just laughed and said they get the job done =)

and here is the only picture i could find of his car that was digital...i hope teh link is clickable..sorry if it isnt. i havnt figured out how to post pics to show up yet. this was taken in 91, about 2 years after he painted it. Has a MSA kit all glassed in except teh airdam..which he goes through about every 5 years lol. and a glassed in fender flare kit. the hood scoop he did him self. i have a second pic im trying to get resized and will post that when i can. sorry if they are big images. and a scary pic of me with a great combover LOLOL omg some one shoot me.

THnx for the quick responses guys... =) Umm Paul quick explanation on one of my statements.. the only reason i was curious about the EFI vs Carbs was because ... 1) im pretty sure both my dad and i are running the same head.. i have stock FI on my 77 and his is carbed.. was curious if that was hurting him. 2) im not quit sure if he used the head on the 81 engine or if he pulled the head off his wrecked z and stuck it on this block..i will find out for sure adn post the answers along with verified block casting number and head numbers monday nite. im hoping that will clarify things even further. his car really does boogy when its throttled right but as i said it sometimes feels as though its not flowing right compared to his original set up.. now im wondering about the flattop/dished pistons you mentioned..once again something i would have not thought aobut until smacked upside the head like just now =0). Maybe if he did switch heads the blocks had diff piston set up.. he was a import machanic for several years before teaching so im hoping he didnt miss that but he was in a hurry as it was his daily driver and had to get it back on the road asap. Mack... does your MN47 have any port work done on it or is it stock besides the top (cam,springs and lashpads)? once again.. thanks for the replies.

and as for "money no object" for my dad that would cover the 6 pack to drive to the nearest u pick it and pull a diff head. i guess i need to clarify a little on my orignal question .....with out doing any porting/polishing...is there a better head for carbs compared to F.I. i know thats a simplistic view but my Dad hasnt ever wanted to really trick the motor out..just the "outside" goodies. like webbs, exhaust and cam. i realized that head work makes a Huge difference depending out how much money you want to spend and what your doing with the car (racing/outox/street) but what about just bolting on a diff head?? most of these questions my dad has asked me to post and to be honest i need the info also. i did come to the conclusion after reading about the maxima head i realize here in OK that thing would just detonate like crazy with the crappy gas we have and this is going to be on a mild street car..with trip 45 webs and mild street cam stock bottom end except for a lightened fly wheel off a 240sx.. he really just streets it, and that very rarely now so he doesnt want to buck up for a modified head....It was his daily driver for about 10 years when he was a high school teacher.. hes just curious if his stock n42 is going to be fine with the heavier springs he installed...umm 10 years ago LOL sometimes..after wiping away the nosebleeds from all the serious indepth uber techspek you guys use..i realize how little i know about cars and how they work. but i am learning that the combustion chamber is where a great deal of power is made..you just have to modify it depending on your engine set up. great info on the heads though.. i know who im going to for my first HiPo head.. just annoyed that i found this site AFTER i moved from Portland. Any Datsun head/engine builders in the ok/ks/tx area that you can recommend to give a shout out to.. Or seems a bit far to drop off a head =) hmmm great excuse to go visit though. THnx Braap and Norm for the replies

after reading this and another head thread.... Ive come to the conclusion that asking if Braap will give details is like asking is the Pope catholic. not that im upset... keep em coming.. im actually learning sumthen as my dad puts it.

i just really like the dual... especially when the second light is placed below and inward like the first pic shows... just helps it have that lowered and hunched look compared to the single... but thats just me =)

holy... umm is that the first gto bodied supercharged bigole honking engine stickin out tha hood drag car or what?? i like =0)

i dont know why...but i really do like the twin beam set up from your first sketch for the headlights.. somethign about that says "fast" to me for some reason. keep up the great artwork though.. love seeing someone work up the ZX.. doesnt get as much attention as it should =)

ahh..sory about that... hadnt realized that there would have been many dicussions on which head to use if carb'd.... what was i thinking LOL basically he is just looking for the right head that is stock for the l6... then putting his cam and valve springs init along with now rockers and lashpads.. i had had a brief thought of a turbo head because i was under the assumption they flow better but i really dont know much about heads other than i have to adjust the lash pads every now and then =).. ill do a quick search and mabye post some refresher questions as to what i find.. once again thnx for the comments and suggestions..

LOL...how odd... i just pm'ed you about being in tulsa and was just talking to my Dad about how a pool table woudl go gret in my den.. and i decided to look at some of your postings to see if you had in pics of your z up and your selling a pool table.. go figure lol

Just out of curiousity for you carbourated fans out their... is there a "better" head to use if you switch to triple webers?? My Dad has triples on his 81block motor ( i positive they are the 40s not 45s) and the head is stock besides the hot cam from motorsports and heavy duty valve springs ... no 3angle valve job or other head work done... has the 6-2-1 header into 2 1/2 exhaust.. sounds great and lopes like a wild animal but sometimes seems to not like to wind up and besides tuning the webers which he has done on and off for about 12 years now.. could the head be the problem?? its the head that came with the 81 block n/a.. any suggestions or ideas...or did i just open a can of worms regarding best head LOL thnx Paul

do you really think i would need coil overs?? wouldnt that negate the strut sectioning and strut inserts?? i thought that coilovers would pretty much elimate the current set up all together? i was looking at MM coilovers in the 225f/250r but thats a bit more money than i want to spend just now.. thats why i was trying for the lowered springs adn correct strut insert so i stop crushing the inserts and bottoming them out. so did i miss something in the coilover section? thnx for the replies regardless of my confused state lol

love the color and car looks great stock... That bodyshape will never lose its sex appeal. quick question though.. do you think they would rub with a airdam on when turning??

Those Tokicos a drop in or do i have to revalve them like some of the earlier ones mentioned?? and yes,looks like sectioning is the route im going to have to take =)
