I'm just wondering if anyone has put any hi-flow TPI parts on a 305? I was thinking of SLP runners, porting the plenum, and if it's worth it looking for a high flow manifold. I want to know if any of you have done this and what kind of results you found? Thanks.

 

Yes, throw a LT1 intake on there and be done with it.

I've got some that came from the 4.3L V-8 in Roadmasters, Carpices and the like. If a little 4.3 V-8 can be run by a LT1 intake then your 305 will love it.

You will not run out of intake anytime soon either, there have been stock LT1 intakes run 10's in the 1/4 mile.

lastly, it's about the same price as a good set of aftermarket runners or base TPI intake.

 

I appreciated the idea but that's a little more custom work then I'm ready to take on or worry about right now. I will keep the idea in mind for later on down the road though.

 

In that case, save your money than for some major upgrades. Not being a dick, but letting you know there is not that much improvement over stock with those parts on a 305. And they are all expensive! Once you mess with more air flow, you should mess with the fuel and igniton too!

 

john millican modifies the intake so itll fit...and its ALOT cheaper the any tpi parts....the runners are 300 the base is another 350-400...and his intake is 400....trust me the guy knows what hes talking about....

talk to him

 

You don't have to do the custom work, I do it for you. It's really just an intake swap after I machine the intake.

 

If you decide NOT to go with the LT1 intake for now, you can get some benefits by porting the intake plenum, at least behind the throttle body.
