A body big block cam specs

Yes 383 A's were a tad choked they say!

68/69 had the best flowing exhaust. 335HP in 69.

The 69 383 Fish used the same cam as the RR and SBEE. The 383 receives up to the 292/509 just fine. Advance it 4 degrees and bamm!

You have a good low end/high end combo JMO! And as far as the 68/69 exhaust manifolds choking it as compared to the B-bodies, I call mostly BS!

My fish had run mid 7's on the 1/8th in the 80's with its stock exhaust.
