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

Re: My Peanut Port BBC 467 Engine Build
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 !

Re: My Peanut Port BBC 467 Engine Build
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

Re: My Peanut Port BBC 467 Engine Build
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. |
