Default My Peanut Port BBC 467 Engine Build

My goal was to build a smooth idle 9.3 compression 467 BBC with peanut port heads (236 castings) then put it in my 1968 Chevelle for a drag test, yes a real drag test. Some pictures as the build went along. The center piece of my build, notice the symbol.........that sure isn't a hump there!

Any pics of the finished intake ports?

Just curious--have you ever tried working a set of "820" heads? They have a relief cast in the chamber by the exhaust valve similar to yours

(pic snagged from the internet)

Yes, I have used them, Its actually a similiar chamber as a 215 or 063 or 290 with that cut out behind the valve.

I've used the 063s -- made good power for a first half-a$$ed open chamber design ... FWIW I am still running these heads with porting similar to Sissel (spell) mods ... TAZ

This will be interesting. I have a late 80´s motorhome 454 with peanut port heads that I´m going to use in my 1974 Corvette. The engine is like new inside so there is no machining required. I´ll put an aluminum intake on it but haven´t yet decided on which camshaft to use.

Keep it coming !

I should clear something up -- the 063s are NOT peanut port. Peanut port heads are normally found on truck engines to build goobs of low RPM Torque. 063s have larger oval ports. TAZ

Those look like the '69 '148' chambers.

Does anyone know the chamber size of stock '148' heads? I've seen a lot of conflicting info.
