My thoughts are the opposite of that.
But I’ve been using the dyno since 1990.
When I want to know how much power an engine makes, I test it.
Built in 1987-
340+.030, Badger stock replacement pistons for 68-71……actual CR unknown.
587 heads with 2.02’s installed. Using the term “bowl ported” to describe the work done to the heads is very generous.
It was the 2nd set of heads I’d ever taken a grinder to(in like 1987).
My guess would be 210-ish cfm.
Regular Performer, Holley 650, 1-5/8” headers, Comp 268H.
What did it make?
