I would say the 904 trans should pick you up .15 .....and the converter should help the 60 ft time which do look soft...I was going to mention the 4.10 gearing but I see only 28 inch tall tires so that is not so bad...
With the 4.10 I might have considered the low gear set for the 904 but it is what it is....

So I think 3 tenth is pretty doable ....have fun

Bought the trans used on here from a member. Its a Cope built unit with A&A brake, billet drum, yada, yada. Dont know if its low gear or not, it could be.
Will find out tomorrow night on the 1/2 shift going down the track.
I just footbrake with the rearend thats in the car, even though its a brake valve body
