grumpyvette Posted June 11, 2009 Author Share Posted June 11, 2009 if its going to have an auto trans and keep the EFI youll want this cam, as its a nice boost over stock, http://www.crower.com/misc/cam_spec/cam_finder.php?part_num=00571&x=51&y=9 if you swap to a carb and a manual transmission, and 3.54:1-4.11 rear gear then this will be a killer upgrade http://www.crower.com/misc/cam_spec/cam_finder.php?part_num=00573&x=51&y=9 personally ID go with the carb and bigger cam here http://www.edelbrock.com/automotive_new/mc/manifolds/chevy/victor-ls1.shtml Quote Link to comment Share on other sites More sharing options...

cockerstar Posted June 13, 2009 Share Posted June 13, 2009 Hey Grumpy I've asked about this long ago back in post #25, but now that it's summer I'm really wanting to go somewhere with everything. I figured this one would be right up your alley. Goal is to have a running streetable motor for a '69 camaro that is as respectable as possible on a serious budget - right around $800. The idea is to have the car running and drivable, doing what we can with the budget. Here's what I already have to work with: 4 bolt main 350 (010 block) with stock lower end 462624 heads 76cc chambers - emissions friendly heads 307 block w/ stock heads and a mismatched (to say the least) cam .501 lift, 292dur edelbrock performer intake w/ 1" spacer freshly rebuilt holley 650cfm carb stock th350 long tube headers built th400 w/ higher stall converter My idea was to stick with the stock bottom end on the 350 and go with a set of 1.94/1.50, 64cc "Camel Hump" heads I found locally. Gasket match them, valve job, and decking. Another option would be a set of 882 heads with new valves,springs,retainers,locs, and 1.5 comp roller rockers, but they're a 72cc combustion chamber. Use the edelbrock intake and holley carb to keep things simple. This is definitely isn't a matched set up, but I'm thinking it could be on the mark considering the funding I have available. I'd need to pick a cam, and would love to upgrade the valvetrain if funding permits. Really, I'm just thinking out loud and am looking for some direction like I was before. Thanks in advance!

grumpyvette Posted June 14, 2009 Author Share Posted June 14, 2009 its very difficult to impress on many guys , just how important selecting good cylinder heads are to the engines potential, both those heads will provide a restriction to flow and result in a significant reduction in the engines power potential let me look around a bit and Ill post some suggestions Quote Link to comment Share on other sites More sharing options...
GrenadeZ Posted June 15, 2009 Share Posted June 15, 2009 Cool thanks grumpy. I registered for the forum and ill keep it with me. The tranny is a datsun T5 out of an 82 Na Z/X. Do you know if a sbc of any kind would mate to a datsun T5 or if any one makes an adapter? Quote Link to comment Share on other sites More sharing options...

misturmoneybags Posted June 15, 2009 Share Posted June 15, 2009 Grumpy, I currently have a 305 SBC in my car, what do you suggest I do to get the most power out of my engine while still making it my daily driver? --thanks Quote Link to comment Share on other sites More sharing options...
rsicard Posted June 15, 2009 Share Posted June 15, 2009 Grumpyvette: I will second the comment regarding cylinder heads. Good heads in combination with good headers, good intake manifold and good camshaft make all the difference when it comes to power. Without good heads, its a LOOSING BATTLE.

B-rad Posted June 15, 2009 Share Posted June 15, 2009 Okay grumpy, here is my situation. I just swapped a BW T5 into my 1975 280Z 2+2. I got the trans and driveshaft out of a 1983 2+2 turbo. My problem is that the driveshaft is to short. After all i have read I was prepared for the driveshaft to be to long but this is not the case. Is it because i have the 2+2 model and it is a little longer? Besides having the driveshaft lenghtened. What are my options? Thanks for all your help.

pezair Posted June 15, 2009 Share Posted June 15, 2009 I want to put a bolt in roll cage in my 75 280z. I found one being sold by swracecars but they say its just for the 240z. Surely it will fit in my car, the bolt in points should be the same i would think? Quote Link to comment Share on other sites More sharing options...

I have a spare set of SBC heads that I believe are the 64cc combustion chambered heads (no accessory holes): 3782461 My question is: Are these heads worth keeping and finding a block/trans for, or should I just get a more modern engine and sell the heads to someone who already has a block? I've been considering a megasquirted twin-turbo lm7 with ls1 heads (or similar) as my end goal, but it's still quite a toss-up to my mind.

lgoodson@pacbell.net Posted June 21, 2009 Share Posted June 21, 2009 Here is my current problem. It seems that my intake is leaking oil. This is a LT1. I will have to reseal it. My question is: Is there coolant running through the intake or not. I am getting conflicting opinions and I do not want to crack the seal and get a crankcase full of coolant. The shop manual says in step #2 to drain the engine. Sounds to me like it runs through the intake. JBC3 says that the intake is dry. What say you?

grumpyvette Posted June 22, 2009 Author Share Posted June 22, 2009 (edited) lt1 cylinder heads don,t flow coolant thru the intake to the radiator like the earlier heads do, the water pump is the exit point for coolant flow.
