Rear gear question

My handy dream wheel says 133 is 10 flat horse power, 600 - 620 HP or so.

1.45 60' isn't hateful. Probably has mid 1.30 in it anyhow. A 3 speed, with the extra SLR should make it 60' a little better. A lightweight 3 speed would be even better.

Depends on your goals. More rear gear, as was said, will help. Agree with a 5800 converter. Beyond that, if it's consistency on marginal tracks, you're probably best with that low gear. Want to go fast, need the low gear a 3 speed would offer. And more tire.

Need a neutral or negative converter to get it to pull off line & the gear change.
5800 stall OK, but there is more to the converter than stall speed.
I agree with tire and rear gear change.
1.96 low might wake it up too, but shift it at higher RPM with a lower low gear PG.
You are carrying quite a lot of weight for a 7.38 starting line ratio...2.52 low gear 3 speed puts the SLR at around 10.33. With the right 3 speed converter it would pick up a bunch. Probably on the + side of .15..

oops!

I have to think the converter is real tight.

My Nova is 3600#, 1.80 glide, 4.10 gear, 28" tire and has 660 HP. I can't go 133; 128 is about the best it'll do but it's usually a 1.40 60'.

So, same running gear setup but heavier and less power.

I would want to see somewhere around an 11.5 SLR

NOTE this is ONLY a recommendation for what might be a good STARTING POINT

5.14 and a 3 speed might get him there...
