I'm upgrading my stock gen IV 502 with only 1 season and 40 hrs on it.
If anyone is interested in the following, let me know. Everything works great. It went the whole season with zero probs. I'll post pics tomorrow.
1. Holley 750 vac sec. elec choke.
2. Edelbrock Performer RPM intake manifold.
3. A/C delco distributor with cap and wires.
4. Polished alum valve covers. Will not fit with Roller rockers.
5. Original flame arrestor
