I think that's two different cars. The 277 car has the short stroke 2.6 and the "STR" car has the 3.2.

I agree though, Uncle Billy your motor sounds solid. Did you do a build thread on it? I searched your post history and coudln't find anything specific.

So I was thinking I might do my build in a couple phases.

1. Upgrade ignition to MSD on current motor
2. Throw on some weber carbs - I see these on the classified: The problem is I know very little about carbs. Bruce Anderson recommends 40 IDA-3C webers with a 34mm ventuir, f3 emulsion tubes, 135 main jets and 145 air correction jets. so...say the above linked carbs don't have those specs. What's the cost and trouble of converting. And what is the 3c1 vs the 3C?
3. Full engine rebuild, put carbs and msd back on.
3. Upgrade to EFI with rassant and EFI TBs

I like the idea of Uncle Billy's with the 9.5 and 9.8:1. Wondering how long the motor has been going and the reliability of that motor.

Thank you all for the help.
