Is this balancer intended for an externally balanced GM Performance crate motor SBC 350 Post 1987 era w/vortex heads, or no? Description does not specify for internally or externally balanced motor.
I have purchased and assembled a 383 internally balanced assy.........will this balancer be sufficient for this application?
I have a 1970 chevy belair 350. I'm thinking of going with one of your 350 performance crate engine 350s. But most are post 1987 blocks and require different flywheel. Do they also require a different harmonic balancer?
