My 340 build

Well i feel the lift will work perfect with my eddy heads especially if i do a light port job.
Also the cam i feel would be perfect woth my compression ratio ill have i hope, might have to upgrade torque converter but we will see. I almost have same setup as you just carb different and heads as for top end

When do you think you'll have the motor up and running? I'm not planning to do the head/cam swap until it's tucked away for the winter.
