I just picked up a 1967 Mustang that I want to build a D/SA. I have a few questions, and appreciate any advise.
1. Must be an Original Block?(Do NHRA/IHRA have approved aftermarket)
2. Must be Original Crank? (Do NHRA/IHRA have approved aftermarket)
3. What intake is allowed?(Do NHRA/IHRA have approved aftermarket)
4. I know NHRA/IHRA approved the Edelbrock heads, Can I use aftermarket rockers with Studs?

I built an IHRA Crate motor car, I was going to build a 1993 Cobra, I decided on a 67 Mustang to match my superstocker...

Thanks
