This will probably be better suited in the Gen IV section. I would call Geoff@EPS or Martin @ Tick and get them to custom spec something.

Which heads are you running? What bore, stroke, and compression? Also I suggest a super victor if its in the budget.

Its a iron block 421 so its going to be 4.030 bore and 4.125 stroke and he said pump gas so it will more than likely he will be around 11-11.8:1.

You're right though we still need what head is going to be used and a super vic would be better on this many cubes.

OP, I see you said "95mm tb" so I would assume you are using an elbow. It has been shown that a car with an elbow doesn't make as much power as a 4 hole tb setup

Give me a call or email Martin@tick-performance.com.

Depending on compression, what cylinder head is being used, what they flow, how big of a shot and how high you want to turn it will determine how much duration and lift the cam needs. Among other factors.
