I'm running a 1980 Ford LTD in a bomber class and I was wondering what the best cast iron exhaust manifolds are for a small block 351W?

Never dynoed a motor with different exhaust manifolds. When I raced a ford on bomber, just used whatever worked. Beat the Chevys anyways, haha. We just used whatever worked and fit in front of the firewall.

use the early 351w pre75, design if you can port them if rules allow but this will do no good on stock heads.

I would say 92' to 96' ford trucks with a 351. They have 2 1/2 inch outlets and the runners are pretty large as far as winders go. hope thi helps......
