Best carbs for tunnel ram

You say street/strip......How much street?......I would consider the 660's a very limited street carb at best.

Just keep in mind that they come with a pretty rich fuel curve. On the R4224, the primary jet and secondary plate are both #76 jetting from Holley and that's pretty fat for that size carb. Also, the secondary openings are 1 to 1 with the primaries.


P.S. On the plus side, the MP .528" cam is pretty mild for your cubes and head flow. I could see 10+" of vacuum with that cam when everything is tuned right, and that's a big plus for streetability with the 2x4's.
