Blown 351?
Is it possible to supercharge a 351m without changing the internals? If so how much boost can I run using 93 octain gas? If not what do I need to do? I'm only trying to get 350-400 HP and torque not street legal.

but I don't know of any bolt on kits available. The amount of boost would depend on your compression, 8.5:1 or less is common. 9:1 is about the maximum recommended.
The compression can be lowered without completely disassembling, by using thicker head gaskets. A .093" gasket from SCE, can lower compression up to 1.5 points.

BDS Systems has a bolt on kit for the 351M/400 motors. It's pretty spendy but hey...it's only money.
