Not Ranked
I have a Keith Craft 351W/427 aluminum block (554 hp, over 580 ft-lbs at the flywheel). I have the 3.44 (3.46?) rear and TKO600 with .82 OD. Rear tire size is 275/40R18. Once I added vacuum advance to smooth out the low end the streetability improved quite a bit (as well as fuel economy). Idles at 900/1000. No problem cruising in 5th at 1400 RPM. Gets ~9 MPG around town and 15 MPG on the highway (both if I'm not hot-footing it). Uses 91 octane gas. Since the engine was installed I haven't had it tuned at all - plan to put it on a chassis dyno for that sometime soon (I had O2 sensor bungs installed in the exhaust sysem). I'm expecting RWHP in the high 300s and probably a bit more performance (both low and high end after a pro gets into the 780 cfm QuickFuel carb - vacuum secondaries). Like someone earlier said the excitement ratchets up a noticeable notch when the secondaries open up. And I'm quite happy with the streetability.
