72 duster resto

Been searching but not sure what thread / cam youre mentioning. Also I noticed a bit of build data on magnums but none on an LA
he has one on a LA360 that's pretty straight forward with stock small valve J(?) heads. iirc correctly it wasn't super wild with KB107's and stock bottom end. but it had a single plane and a fairly rowdy cam, and made just shy of 400/400.

the one magnum build he did was super impressive. if not for milling the pistons that would be a copy cat recipe all day long.

let me look...

ETA: found it Street 360 W/.528" P.S. Cam

basically a MP 528 purple shaft solid w/ a street dominator. but the whole thread is worth a read. he mentions that because the heads are a limiting factor, a dual plane and smaller cam would probably make the same power and behave a little better.
