wasnt really sure where to post this but, is it possible to have a half decent fuel economy while pushing around 500 hp? really hard to do? mildly hard to do? not even possible?

 

The LS1 guys do it all the time. The recipe is simple. Ported or aftermarket heads, a TR220 cam, headers, LS1, T56, 3.73 or 4.10 gears. And 27 mpg hwy on a regular basis.
to do it with a traditional SBC, you'll have to use nitrous or boost, AFR180 heads, and a high lift cam with a good smooth idle.

 

well, i got an LT1 the other day. it had been sitting outside for awhile without the intake manifold on sooo... yea. cant complain though because i got it free. its goin in an 86 firebird that i bought from a fellow student for $300. first project car, its probably gonna take me alot of time and money but i wanted to go naturally aspirated. its a learning experience and im still learning alot. i was thinking of stroking the engine out to a 383. it'll probably be a little while before i get the money to really start doing anything so ive got some time to learn. ive already learned alot from this site, its awesome.

 

I suggest you check out the LTx sub-forum over on www.ls1tech.com you'll learn lots from those guys.

 

alright, thanks
