About 5yrs ago I bought a new rebuilt short block with a P4286681 cam in it just wondering alittle about the chacteristics of this cam looks like this will finally be the summer I put it in my 71 Dart

The engine's static compression ratio needs to be in the 9.8 - 10 to 1 range for that cam to work well so don't use it in a "stock" engine, with no other changes.

The engine is bored .06 and the head was milled if I remember right about .106 but I'm not sure I will be checking the cc's first and it will be alittle while before putting it all together The head was also lightly ported
