Harold I'm changing my plans and am running a different big block. It's a 402 with a little under 10:1, probly around 9.8 or 9.9, oval port heads, performer rpm intake, 750 holley, headers, msd ignition, and a 4 speed probly with 3.42 gears. Would the 262 voodoo still work alright with my comp or should I go with the 268. Thanks Kevin.

Kevin,

The VooDoo 268 would be the largest I would run with the 3.42 gears. The VooDoo 262 gives more vacuum, if that is a concern. Either would work just fine, with the 268 sounding 'racy-ier', and the 262 being better in heavy traffic and cruising on the interstate.

Thanks again Harold. I was just concerned if the 262 would be a tad small for my comp. One more question, does the 268 idle more rougher then the 280/288. Thanks, Kevin.
