360 head porting for big power (500HP ?)
Back to the humble 'J' heads.
Anyone called John like me will love a 'J' head.
A company called Weslake engineering did some 'back in the day' (1970).
I guess they were tied up with the hemi ban in Nascar and like Keith Black etc, were doing S/B work.
Nothing like the KB and Mullen infamous 305 Nascar engine of 1971.
