I agree with tourque. Don’t try to reinvent the wheel. If you changed that much gear ratio out back and the taller tire with no change in ET, ya need to get in touch with your converter guy and talk about why that is. That’s where you’re missing it in my opinion.

As the fast guys here have pointed out , Takes a pretty stout piece to pull that gear. If you know how much power and torque you make just do the math. T X first gear X rear gear. If your converter person is good they can give you a multiplication number to factor in also. You’re giving up approx 500 foot lbs of multiplication from 1.69 to 1.58. Can you afford that? Your car sounds like it’s good as it is.

You’re way out of your shade tree mechanic league retard. assembling junk for your local naive and clueless street/strip crowd running combos from the 90s.

I ended up with a 1.80 and 3.70 with big bubbas. This was a roots blown hard tail that rolled across the scales at 2050. I liked this the best as I started out at 1.80 and 4.10.
I went 6.30s at high 21x mph with the 1.80/4.10 with 18 degrees out at the hit. With the 1.80/3.70 I went some 6.20s at 225 mph and had just a tiny check mark in the timing at 0.2 seconds and actually opened a lean out around 0.5 if I wanted to pick up a little.
That was with a converter that flashed around 6900 and shifting at 8300-8500 and fall back to 7100.
I had a 1.69 briefly with either 4.10 or 3.90 (can’t remember) and the car liked it but the gear set only lasted a year or so.
Just throwing out a little more data for you to ponder. For a 4.40 to 4.50 car, 1.80/4.10 should be the sweet spot but 1.69/4.10 would be a little tamer depending on the track.

about your latest claim aka lie, again without a shred of proof, with out details as is always the case.
Meanwhile those that know, those that race a "medium" dragster as well those that race a much quicker TD have unanimously stated that the OP should be running a 1.80 gearset.This message has been edited. Last edited by: 1320racer,
