Racin_Jason Posted June 23, 2002 Share Posted June 23, 2002 .030 over 350 TRW forged flatops (compression 9.2-9.6:1) AFR 195's (stock port/bowl) Perf RPM manifold Comp XE268 shorty hedmans dual 2.5 to single 3" I have a Carter 625 vacuum, elec choke now. I'd like to know what the gains of a edelbrock/carter 750 would be on this engine and if its needed. The 355 is in a 2500Lb 240Z street car that will see rare strip duty. Im assuming vacuum secondaries would be a better choice, but I'd like your opinion on that also. The rest of the combo, if it will help your judgement, is a 700R4, 3.54 gears and a 25-26" tire. Thanks for any input here Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted June 23, 2002 Share Posted June 23, 2002 you will probably see a small gain in high rpm hp with a vacume secondary 750cfm carb but unless your willing to do other mods like a new cam,super victor intake and lower rear gears I would not bother, youll likely spend several hundred dollars for a 5-8 hp gain in only the high rpm range and a slight loss of streetablity with the change of just the carb. I personally would not do it on a daily driver. if you want to get an idea of what you might gain , install a 2" open center carb spacer under your present carb (take the hood off just for testing if it wont fit) youll get a good idea of what the larger cfm airflow will do for you, without the expence.
