305 TBI in Chevy High Performance 294hp 378 lb of Torque

Has anyone got the new issue of Chevy High Performance? In it there is an article about a 91 RS 305 TBI.

They use the new GM Performance Parts Vortec style TBI intake Manifold, along with some L31 Vortec heads, a new Crane Cam w/ 1.6 rockers, and Edlebrock TES headers & Catback.

They made nearly 300hp from a 305 TBI and there not done yet, there is a part two. Can't wait to see how much horsepower they can sqeeze outta this thing.

Anyways I just think it's cool to see a performance magazine do an article on a TBI car for a change.

They were milled both on the bottom and intake sides. They also are ported and set up to accept larger lift cams. We have a good thread started right now so I will shut this one down. Check it out though because I have spoken with them and we have uncovered some details
