SRT8 392 camshaft is Part # 05037379BC. NON MDS
215/221 @ .050"
.574"/.551" valve lift 1.6 intake/1.65 E ratio
121 LSA
108 ICL
SRT8 392 MDS 05038419AB
@50 Exhaust 215 on 4 lobes for MDS

The SRT392 spec 591/559 , it uses 1.65 as a Intake ratio,Not 1.60



I've been a long time Ford guy , my kid and buddy got me in to these G3s the potential for the G3 is just awesome. My 496 FE makes about 690 hp, my 408 G3 makes about 690 Hp both do it with very similar cam specs.
