I should trap at 7300 rpms in the 1/4. my 496" set up was a street/strip combo; pump gas and I used nitrous at the track so the 4.10 worked well. Now I am going to run all motor with a taller tire and the 4.56 seems to be best for wringing everything out of this combo. Sounds like you have figured everything in. My 2-cents with over 500 CID is to start with the gears you have now (4.10), that might be just fine. After running it that way for awhile, you can always put more RPM to it later. The car might mph better than you think (145 vs 138?), and drive the RPM up accordingly. And all that torque will likely pull the 4.10/31" just fine (especially if you are running a torqueflite). 1993 Daytona, 5.50 at 130mph (1/8) 1.19 sixty ft (PG). Link to 572 B1 - Part 1

Why spend MORE money when You might not have to! Even though you're going with a taller tire,with ALL the torque that 540's going to make,I would say try what ya got first! Just my Randy

New tubs and body work are done, now I just need the motor and am ready to go. this time the car will be 250lbs less and 100+ hp more than the last time we were all there in Sept. a few yrs ago. Cool....looking forward to seeing it run ! Ron
