BOOM! Bang on! Mike drop!
AJ with the big mallet hitting the nail on the head.
Gotta love this.
Everyone is suggesting a higher than normal gear based on two factors. Your statement of you don’t care about mileage, just the fun factor & you too low of a stall converter rating. The extra gear will help a lot with a stall too low & add a good amount of zip on take off.
AJ’s OD suggestion may be a bit pricey and such since you all ready have your trans done but the advice makes sense. Do the basic math.
OD Ratio multipled by rear end ratio =‘s final drive ratio.
4.30 X .69 = 2.96
4.56 X .69 = 3.14
4.88 X .69 = 3.36
See where there going....
It’s pricey but the best of both worlds is now coming to you really well. Re sell the current 904 & converter when your done for a recoups of funds.
