Hey neonracer, there is a new issue of “Camaro Performers” mag on the shelf. They do a simple low-budget build-up on a 305 and get 350ftlb and 372HP out of it. They used a stock 305 that was lying around in their garage (dished pistons - low compression) and standard flat tappet cam. Yours probably has the flat top pistons (tbi motor - higher compression) and roller cam, so you would do even better. They did not rebuild the bottom end, it was left factory.

The key components were Enginequest Vortec 180cc heads that they milled 0.030 off to get 60cc chamber size and a Comp XE268H flat tappet hydraulic 224/230 @ 0.050 & 0.477/0.480 lift (you could probably do better here with a roller if your motor is already set up for a roller cam.

They added an Edelbrock RPM air-gap vortec intake and a 650CFM Demon carb (pretty standard stuff).

No prices were given in the story except the retail on the bare heads which was $225 each.

Just saw it yesterday and thought ya might wanna grab a copy. :bigok:
