Got my eye on a 4.88 but not sure it will fit the factory housing.
Also have a new 351w based 460c.i. Ford crate engine going in soon.

I know I've seen something in the 5.70s before. Maybe 5.73? What is the application that you would need that much motor and that much gear? Even for 1/8 mile racing that's a lot of gear. It seems like maybe you haven't thought this through very well.
The application will be for fun only on the street. Low gears and big torque. I have other things I can drag race at the track.
Thanks for the info. I've never had or worked on a bone stock Lightning with the stock rearend. Only highly modified stuff with a 9 inch.
"Way over my head"?.....LOL Yea your probably right.
lmao. Pair them with a 4000 stall converter. You'll tack out at 3 mph in first and sound like you have a blown clutch when pulling out....

What's the RPM range of that motor? I think a 4:88 would be awfully steep for it. I'd go with the stock rear and a looser converter.
Wondering if he has the Z460 Ford Performance stroker. It makes 575 Hp @ 5500 rpm. If he does, I'm sure that he is not running the factory computer and rev limiter.

The engine is 0-6000rpm. Was thinking steep rear and stock converter. The 460ci should idle at 800-900rpm easily and I know it is making 550ft lbs by 3500rpm. I just really dislike loose converters. Maybe Ill leave stock gears in and try it first.

Yeah its the z460
This engine has a SCAT forged crankshaft and SCAT h-beam rods. With the hydraulic roller cam I'm sure the crank and rods are safe. We have run 4.56, 4.88, and 5.14 gears with shorter tires than the Lightning on small to big engines without any problem in the 1/8 mile. The last engine was a stock 351W with Victor Jr heads and roller cam. Shifted at 6400 rpm with 4.88 gears and 28" tall tires. His engine with 4.88 gears would be fine from stop light to stop light but probably be too much gear for the full 1/4.
Also, people ran race cars for years without any rev limiters. Over revving this engine until it self destructs would take some serious effort and abuse.
Thanks for the info fellow Lightning owners!
Does anyone have a rough estimate how much power the stock trans will take? Im not planning on slicks, drag radials, etc. Just street tires.
