I did a 3.4 crusher at my work with a 3.5 upper/6.5 lower and stock manifolds and that made 20-21lbs. I'd say with you being stock lower and with longtubes you'll be in that 20-22lb area.

What's your fuel setup and other mods? assuming a pump gas with very little timing in it I'd guess 630ish. The car I mentioned above on pump gas made 629whp. if you're going to be using race gas/torco/e85/meth then 700+ hopefully.

i have a fore fuel system with 60lb injectors havent checked the pumps but im sure there is plenty there. I just want to make sure the car is nice and safe..

22lbs might be pushing my luck

4.0 upper stock lower with LT I saw 20-21. 3.5 I saw about 23-24

if I may ask , stock manifolds is not too hight pressure for the engine with this Whipple 3.4 ??

Think ill be okay if i run octane booster in every tank. Its not a daily driver by any means

isn't e85 every where in Iowa. Throw some bigger injectors in and have some fun.
