my Low dollar 318 hop-up project

this "spread bore" design will help with the cast intake spread bore design.......

These are Square bore based but Spread bore design by the ports.......

I can still smell gas, so this was run not very long ago, which is nice! I'm betting this is a bolt and go. However, I would like to say that if anyone is breaking in a new cam, be sure to use a carb you KNOW is in great working order. You do not want to fight a carb when you are trying to break in a new cam.

I would also like to add that you can go 100 cfm's more on a dual plane than a single plane intake. In other words, a single plane intake with a 500 cfm carb is like a dual plane intake with a 600 cfm carb. Obviously I have the cast dual plane intake, the 600 cfm's will be just fine.
