Guest Dylan Posted June 9, 2005 Share Posted June 9, 2005 I am starting out my '71 Z project and will be buying an engine fairly soon. It will be a 350 sbc with WC t-5. Can anyone else with similar setups tell me how streetable it is with your torque and HP. I want to max out performance while keeping it available to drive to work sometimes too. I was thinking about 400-425 HP with a fuel injected/aluminum head setup. Thanks Dylan Quote Link to comment Share on other sites More sharing options...
Guest iskone Posted June 9, 2005 Share Posted June 9, 2005 Ahhh man, Hate to tell ya but your gonna have to do some searching "streetable" is just way to relative a term. IMO 400hp is fine but others will tell you as little as 200-300hp 300 being the MAX in a Z. Figure out what you want ans so on and so on Isk Quote Link to comment Share on other sites More sharing options...
580z Posted June 9, 2005 Share Posted June 9, 2005 well, I have a 355 with a WC t-5 in my '72. Very streetable, but that may change after the twins go on. Keep in mind that first gear (if you use your stock rear end) will be nearly unusable.................. Quote Link to comment Share on other sites More sharing options...
Phantom Posted June 9, 2005 Share Posted June 9, 2005 I'm running 365 flywheel hp with T-6 & 3.70:1 R200. Car is extremely streetable but 1st gear is only necessary when in a really big hurry. Quote Link to comment Share on other sites More sharing options...
Pyro Posted June 9, 2005 Share Posted June 9, 2005 A 400 to 425 hp 350sbc with not normally have a smooth idle. It takes a long duration cam to get that power. If the idle doesn't bother you then you will be ok. I have had all kinds of cams in my 240 with a 350/T5/3.90 gear. The small cams are nice at the stop lights or sitting in traffic. But the rpms are greatly reduced which is a bummer with a big engine in a small car. By the timing the tires quit spinning it is time to shift. (bummer) The cam I enjoyed the most was the compcam 292H. Rough idle but cleaned up right off idle and reved to 7K with heavy valve springs. At least a 400 hp cam. A long duration cam but with wide lobe centers (114 to 116) would smooth out the idle of a big cam while maintaining high rpm potential. Would also would well with efi. Would make a very long but lower torque curve. Good for a V8 Z street/strip car. I never tried that combo because I have always ran a carb but I'm sure it will work great with efi. Of course, cooling will be the biggest issue. The stock mechanical clutch fan with a custom shroud on a HP cross flow radiator will work the best. If you go electric fan, get the most cfm possible.

Guest Dylan Posted June 11, 2005 Share Posted June 11, 2005 Thanks for the replies..I was trying to gauge weather 400hp is more frustrating sitting in some traffic once in a while then the added benefit of the increase acceleration. So far it sounds like I can handle it but please any more responses would be nice. Quote Link to comment Share on other sites More sharing options...
280zwitha383 Posted June 11, 2005 Share Posted June 11, 2005 Well, when I gauge weather it's not usually in HP...... Quote Link to comment Share on other sites More sharing options...
