Right now a full roller 489 BBC, it's 10.89 to 1 and dyno'd at 640 on motor with a too small carb, I'd say it's closer to 650 and I use a 180 jet shot of nitrous, I tech for 10.00 so have it tuned to run in the 10.1's, right now I'm running a built turbo 350 with about a 5000 stall off the foot brake it pulls 1.39 60 foots.
Some day I'll finish off the cage and tech it for 8.50, next motor will be race gas only as that's all I run now and will be a 582 or bigger, shooting for 1200 on motor and running 8's, just not sure when it will happen.
Here's my current setup
