Tire diameter should be considered as well. Radial or bias ply will play into the equation too.

Back in 1992 I went 10.54 at 123 mph with a 5.13 at the Snowbird Nationals 29.5 Firestone slick crossing 7600 rpm.

Nothing burger cast crank BBC 427 600 lift flat tap, steel Merlin heads 3475 all steel Nova

That was flying in 1992 home built on $10.00 bucks an hour.

I'd put a 5.13 in it. I learned the easy way in 92, the first 100 ft makes you.

Wasn't the 5.00 gear created for these combos?

When I at Ford they were making 5.20s and 5.00 cause the 5.14 gear is a week design because of the tooth count.

Aren't those (5.00 gears) hard to find for a 12 bolt?

I know they were custom built. Awhile back they were getting a group together to order some.

You may want to try Indy Gear. Many times they carry unique gear ratios and be prepared to pay a premium.
