carb for slant 6

To Run that 600 CFM, Cam swap 264-268 Duration, Head Porting/ Milling 9-9:5 CR, Headers 3.23-3.55 gears. On a stock slant six Two Barrel Carter BBD is the ticket, I have found that a four barrel on a stock slant will run slower than a two barrel. Once you your increase Compression the four barrel really shines through. Good luck!

The BBD is only about 193 CFM. That's about HALF what a Jeep 238 can handle according to the Jeep guys and probably close to the same for the 225. The 600 can be tuned to run on a stock slant just fine as long as you upgrade the exhaust. It flows less than 300 CFM on the primary side. As long as it's tuned so the secondaries don't open too early and with the right power valve and jets, it will run good. I've done it before. Will likely do it again, although with something like the Street Demon.
