difference in runner size?
is there a difference in runner size from the 305 TPI and the 350 TPI in stock form? i know the 350's injectors are bigger, but is the intake system the same or is the 350 larger there too? please help

The TPI manifolds are indeed the same for 305's and 350's. The TPI manifold was originally engineered for the wee-05. When the 350 came back into production, GM chose not to change any of the castings, cheap 6astards. Even in stock form, the 350's performance is hindered by this engineering short-cut, so your 305's manifold will work on a 350, but an aftermarket base and/or set of runners will help your 350 breath closer to its full potential.
