383 240z Posted March 27, 2002 Share Posted March 27, 2002 OK here goes I have a four bolt 350 block with ARP studs and windage tray, a stock 400 crank swinging GM rods with ARP bolts topped with speed pro pistons (part number L2491.030(Forged)) I was wondering if anybody could point me to a good head cam combo for this engine. The other parts I have gathered are 7/16" ARP rocker studs 1.6:1 roller rockers I would like to keep them. the other variables are a TH-700R4 with a 3000 Stall 9" non-lockup converter and a Dana 44m Diff from a 1982 Corvette (3.08:1??) the projected tire size is 255/50/16 (more once the coil overs are installed) I'm not opposed to Iron heads if the will work they may be heavy but they are cheaper!! I may add a little blue bottle in the future. The car will mostly see street duty but WILL be on the track at least once a month!! I am a bit concerend about the compression I would like to run on 89 octane but if 94 would be better I dont have any issues with that. Also if yoou could give me a estimated HP & Tourqe figure that yould help. Thanks much I love this board!! Keith Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted March 27, 2002 Share Posted March 27, 2002 those pistons are for a 383 and will have about 10.6cpr with a 64cc head and about 9.4 with a 76cc head, so if your going to use the cheaper iron heads ,get the 76cc size if the cam is mild but if your looking for a kick butt high rpm combo the cam with the higher duration will bleed off some compression allowing the smaller head combustion chambers, FMP L2491F 383 10.6 9.4 FLAT 5.7 F 1/16,3/16 497 311.95 heres what I would suggest to get the most for your money,match the CANFIELD 223cc heads to a CRANE #113841 solid lifter cam and a #2925 super victor intake to a 750cfm carb with 1 3/4" headers http://www.canfieldheads.com/sbc_2600.html http://www.cranecams.com/master/apps/chevy21.htm#1.%20PowerMax that combo will get you about 460hp/460tq and will work GREAT WITH NITRIOUS Quote Link to comment Share on other sites More sharing options...

383 240z Posted March 28, 2002 Author Share Posted March 28, 2002 Thanks Grumpy!!! I was wondering if there are any chevy heads that will also work I come across some great deals on fresh heads. Are there any particuler casting numbers I should be on the lookout for?? Or should I start saveing money for the canfeilds?? Keith Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted March 28, 2002 Share Posted March 28, 2002 casting #s 10239906 12558062 vortec cast iron heads THESE ARE VERY GOOD IF YOUT ONLY LOOKING FOR ABOUT 400hp casting # 12367713 aluminum fast burn heads pontiac style aluminum casting# 10033867 bow-tie raised port aluminum casting # 10134363 are all reasonably good but rare heads Quote Link to comment Share on other sites More sharing options...
383 240z Posted March 29, 2002 Author Share Posted March 29, 2002 Ok then I will hold out for the canfeild heads also what kind of intake and carb yould you recommend for my application? I can't thank you enough for your recommendations and the tech artical's you post oh so often thank you again Keith Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted March 29, 2002 Share Posted March 29, 2002 the victor jr (edelbrock #2975) and a 750 carb are about ideal for a hot 383 combo if theres any chance of hood clearance problems (its still fairly tall but it works very well with those heads) a 700cfm carb works slightly better on a 350 BUT be aware you may need a drop base air filter and possiably a hood scoop with any high rise intake,look here, http://www.ramairbox.com/ Quote Link to comment Share on other sites More sharing options...
383 240z Posted March 29, 2002 Author Share Posted March 29, 2002 I'll be putting a small order into summit soon.is there a set of rings I should get? or any that I should stay away from? Keith Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted March 29, 2002 Share Posted March 29, 2002 I use these on my personal engines , http://www.totalseal.com/totalseal3.html they cost more but I feel the GAPLESS RING SETS ARE WORTH IT Quote Link to comment Share on other sites More sharing options...
383 240z Posted April 7, 2002 Author Share Posted April 7, 2002 Hey Grump thanks for the info thus far I was just reading some of your other posts about roller cams and since I have not bought any cams ot lifters yet I was wondering what you would recomend to go with a full roller set up? I only plan on building this motor once and dont mind waiting to get what I want! Also were do you recommend I purchase those canfeid heads?

grumpyvette Posted April 7, 2002 Share Posted April 7, 2002 this cam http://dab7.cranecams.com/SpecCard/DisplayCatalogCard.asp?PN=119661&B1=Display+Card is an excellent hydralic roller cam for HOT STREET STRIP use in a 350-400cid engine, but be aware that you can,t run it with stock un-machined chevy heads without running into serious coil bind and piston to valve clearance problems on most chevy heads and each combo is differant so no one cam fits all or even most combos, and you need a .600 valve lift clearance to coil bind MINIMUM to run this with 1.5 ratio rockers .650 with 1.6 ratio rockers while still maintaining a .100 intake /.125 exhaust to piston clearance.
