Comp 35-512-8 is a 351/302 h.o. roller cam that is speed density friendly. It's about as aggressive as the SD system for a 351 bronco will handle.

I'm not sure what firing order you have, but it's fairly easy to swap.

Lobe separation and duration are the limiting factors for the speed density system. For a 351 in 94 that is and lsa of 114 or higher, and I believe a duration about 224 (dont quote me on that)
