660Z Posted June 30, 2002 Share Posted June 30, 2002 Just getting my 240 worked out and in 2wks i`ll be heading to the test and tune.I think I know what the car will do but I would like you best guesses! I have a 73 240 400sbc "stock" at least in my opinion. It has #882 heads 194/150 valves,an LT1 cam,flat top pistons (10.1cr), a cast iron intake w/a 830 holly dp carb. stock HEI. The trans is a turbo350 2500stall 11 inch r200 rear 3.55`s Now this same motor with a 750 vac sec carb ran 13.8 @101 in my 68nova with 3.23`s and that car weighs every bit of 3400-3500lbs.so if a 240z weighs 2500lbs. Im thinking 12.8 @105 with the cast intake (top end restrictions) Everything ran through exhaust and street tires just like my nova at the time....what do you think it will do?....mark Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 30, 2002 Share Posted June 30, 2002 lets say you had 8 inch wide tires and 3.23 gears with turbo 350 and 280 hp at 4800 rpm and shift at 5500 and 3600 lb car with 2500 stall 13.9 at 101 now take that in the z and now with 8 inch tires and 3.55 rear with tires 24 inches tall( said the tires on nova 28 in) and 2500 stall it will turn 12.20 111mph Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted July 1, 2002 Share Posted July 1, 2002 I think you pretty close, I'd imagine it will run from 12.5-12.8 depending on if you can get a good bite of the track. One things for sure, you'll get alot more Gee Forces in the Z than you ever saw in the Nova... Regards, Lone Quote Link to comment Share on other sites More sharing options...
