I sent mine to Bullet, they took all my info about the car and planned use and sent this back to me. You'll have to get the adapter for the mechanical fuel pump for the Magnum cam. The cam is going into a 67 Barracuda convertible so it's a little mild. The top end of the 90 360 is Magnum heads with some pocket/valve work so the final lift is .459, just a cruiser with some snot.

Talk to them and explain what you want, I've built too many over cammed motors to make that mistake again. They turn on at 3 g's and suck from idle to then. They ain't fun in traffic!!!! The only other problem you'll encounter with this is you'll need new pushrods. The smaller base circle will mean a longer push rod.
