My Peanut Port BBC 467 Engine Build

[VintageMusclecar]

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 !

Heres you go Anders.... more pictures, the crank GM 7416

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.

Thanks. I love what you are doing with peanut ports. Wish they made them with early 100cc chambers, as they seem like they'd be perfect on a 396/402.
