I'm building a limited mod. I am attempting to re-build that class down here in the southwest. I have a retired Jr dragster raptor, stock stroke, stock bore, stock cam, stock head, Tilly HL3??. I have an ARC 4.5'' rod that showed up at the house today. I plan on buying a Weisco 1990P2. Is the Dyno 126 a descent cam option? Also, I am seeing that AKRA Limited FH rules state that head depth can be no less than .400" to the spark plug pocket. What other suggestions can anyone give me to make this thing live a while? I want other guys to build them, or dust them off and bring them out, but I certainly don't want to be blowing this thing up al the time. Thanks for the input.
