To swap in an LT1 cam with a ported plenum and SLP runners, along with 3.42 gears and my current mods. I also just ordered sfc, and the steering box brace. How much HP/TQ would i gain with the cam, plenum and runners? any help is appreciated

 

i heard from other people that the LT1 cam works great in a 305,especially w/ a 5 speed. u should check w/ Comp Cams for specific cams for ur car if ur gonna go all that work to change the cam,may as well gain the most that u can...if u have the $$ and everything,hope that helps
