360 Magnum Build w/ V Belt Configuration Question

Just be careful of your timing and know your going to use 93 octane. Your not going to be able to run a lot of advance at your compression ratio and that tiny cam.
My build on the wife’s car is the same as yours with a Hyd roller cam @224@050. It’s an LA cam. The lift goes to .570-something with the 1.6 rockers

You may have to feed that some race fuel.

Once ironed out, that’ll be one snappy engine.
