My duster (408) will run low 9.30’s maybe a high 9.28 around 140 mph so even a stock location pushrod can make enough horsepower for 90% of our members. Then we have Indy heads, W8, and W9 guys that want to go quicker. Hopefully the Edelbrock Victor comes available again but that won’t happen unless guys speak up. I think the postie would like an aluminum head (magnum based) slightly better than a cnc ported LA based Speedmaster head. This keeps the price down for the 80% guys looking for a 400-500 horsepower crate engine. If Speedmaster produced a cnc magnum head with a 2.055 valve he could grab one off the shelf and do what he does best. Build engines and ship them out. I know who I would be on the phone to.
