Big horsepower 318 builds
Well there you go. How easy is that? It’s 23 HP from 500. I’d never, ever use that intake manifold. Ever.
Not sure what they had for headers, but 1.875 primary’s and a 3.5 inch collector is what I use. He’s a point LESS on compression that I’d use, but that’s what he was limited to by rules.
He used the best pan, but I didn’t care for that pick up.
Add a crank scraper and a cam with the timing for 11.5:1 on pump gas and that thing EASILY goes over 500.
Next, you could add TF heads and reduce the duration some and gain even more power.
It’s not that hard.
