Cam for a 360 build with the parts i have

What converter are you planning on and rear tire will you be running? Do you have hydraulic or mechanical cam now? Save your cam and lifters together, those will sale on here. If you have the funding, a custom converter is well worth the money. Precision of new Hampton, PTC, Frank Lupo, Precision, etc. They are built around your final combination. 450 hp is very doable with the RHS heads. I would probably go as far as to contact Ken Heard at Oregon cam grinders. But if I were to go with a shelf grind and get the converter tuned around it, I’d probably go with an MP 284/.528 solid cam.
