Reply to "What carbs are you using on your Cleveland motors?"

The Holley HP series carbs are what one needs to tune the air/fuel ratio on the car, if your car doesn't need a choke. However lets not try to be too intelligent here it will likely make us look very stupid.
These are really no easier to "tune" then the Weber IDA's are. No harder for that matter also.
The Holley advantage is you don't have all that linkage being directed in ways it doesn't want to go and you only need to deal with four throats instead of eight.
Your guess is as good as mine as what the proportion of fuel to air is going to be.
It is unlikely that they will be the same as the Webers of 140/160 on the Cleveland.
The single carb plenum has a diferent requirement then the IR manifold does.
Then once you find the ratio you need to find the size that the fuel jet should be. It is possible that you might find the main fuel jets should be small, like a 62, but I doubt it.
Incidentally, I hate to tell everyone this. Don't hate me for it.
The Holley has emulsion tubes too.............
OK, everyone finished cussin' now? You just can't change 'em...yet. Yeha!
