Cam and carb suggestions

Just ran some numbers on the OP's parts combination for static CR, assuming 70-72 cc chambers, and come up with 9.1-9.3. The SRP pistons have a .036" lower compression height than the stock ones. So even with the minor milling to flatten heads and block, it is gonna be below the stock SCR.

So, IMHO, I'd not go too big. I looked at the first cam suggested and thought it would be a pretty good cam for spending a lot of time on the street; good lift to duration ratio. But as said, you need to check lift clearance on he heads in the retainer-seal-guide area.

As said, you'll be challenged to spool it way up in RPM from a light with the 2600 TC, but with a cam like that 1st one, that rear gear and tires, it is GOING to spin tires plenty with that TC. My son's 340 has a similar cam and with a 3.55 rear and 2200 TC and it will spin tires from a top with half throttle.....true SCR is 10.0. Your lower SCR means you would have to open the throttle more but you'll have more torque than traction. It's gonna be a wee bit stouter than the /6 LOL!

600 to 750 on the carb IMHO.
