3:73 or 4:10 in a 347 Stroker...

i bought a 5 spoke posi built rear that came out of a cobra. It has the moser 31 and all that good stuff and 410 gears. My car now has stock rear with 373 gears. question is, should i slap that rear in and stick with the 4:10's or should i put the 3:73's in there. this is all going in a 87gt with a 347 stroker and stock t5 trans. street/strip car.

Since the rear is all put together & set up for that gear I would put it in as is, & if you think the 4.10 is to steap you can go back & change it, it's not any harder after it's in the car. Usually has to go to the shop to change anthow unless you want to chew up some gears or you have equip to do yourself.

If your not breakin' parts your not building enough power. Big cube small blocks ROCK!

I think the 4.10 be a bit steeper than you'll like for street. Especially with the 347...And freeway driving...And gas $3.50/ gal. On the flip side just start in second gear right!

Try it out it'll be fun to drive! And like fastford said it's easy to swap once in the car.

I think it depends on your camshaft. If you have a mild cam, then stick with 3.73's. If you have a cam that builds horsepower at higher rpm, then go with the 4.10's to maximize performance.

Have you truly entered Jesus ONE "Kingdom of GOD" or the Holy Catholic and Apostolic Church through "water (baptism) and Spirit (Laying of Hands)" John 3:5 ??? Jesus fulfills Ezekiel 36:25-27 prophesy. You see entering the Early Church in this same pattern in Acts 2:38 and specifically explained in Acts 8:14-17 and Acts 19:5-6. Enter His ONE "Kingdom of GOD" to receive Jesus as the "Lamb of GOD" (John 1:29, 1 Corinthians 5:7, 1 Peter 1:19) for ETERNAL LIFE John 6:54.

Also what size tire are you running? What kinda powerband are we talking about? Alot more to picking a gear set than just slapping it in there. Don't fear the gear
