Re: BBC GM 3904362 Camshaft Questions
I believe it is identical to the #143 cam.This same cam was used on certain 1967-71 solid lifter 396,427 & 454's.
Specs for it..
.520 intake lift
.520 exhaust lift
316 intake duration
302 exhaust duration
1.70 rocker ratio
Does it reflect a casting symbol of OMO?
