Re: tpi 305 mods?
what would you mean by saying that you want just good enough horsepower. tire squeeeeeeling or sit you in your seat. i mean high flow intake pendulum and runners would help. i decided to keep my 305 as well. i am going to do what i listed with new heads. also like 89305formula has in his sig. descreen the maf and get something like the slp cold air intake with air foil and you'll notice a diff. to start with.
