I Have... 521.. P-51, New TFS Street Mafia Intake, 13.6CR, 272/284 780 Lift.
In a... 66 Fairlane..

What carb spacer do you think i need? Base plate of manifold with out carb on is one inch below the bottom of hood... I planned on a Prosystems carb..

I know i should strap it to a dyno and find out, but no one has one within 200 miles of me..

Thanks..

Trial and error, if you are going to do it without a dyno.

Trial and error if you're going to figure it out using a dyno too! Spacers are something you just have to try to see if they help, hurt or make no change. Most of the time I test an engine without a spacer, then go to a 4 hole, an open and a merge. Keep in mind too that the most expensive spacer is often not the most effective on the engine.
