actually my setup is a 305 TPI with the dual cat, borla catback and a vortech s/c
After reading many posts about gaining hp I'm still not sure if i should take some new heads for the 305 or buy a 350 engine.
the actual engine has 65kmiles on it and the last ~5kmiles were with a Vortech s/c.
it is leaking oil since the first mile with the s/c on it and i think it will need a rebuild after tearing the s/c down.
I'm looking to be in the 300-320hp (flywheel) range.
what would you do and what parts would you buy?

Thanks alot for the help

Those HP numbers with or without the vortec?

 

it was before the install

 

I'd have to say get a 350 shortblock with some decent heads like trickflows. Then put the 305 tpi on top of the 350 with 24lb injectors without SC but with SC 30 lbs. with SC should be in the low 13s. depending how many pounds of boost id say 12 lbs of boost would put you in the 12's. just my opinion later man.
