AKA, I change the low gear ratio and rear end ratio in my old NHRA legal M.W. 1963 415 HP Stocker, took out the 4.89 rear gear with the stock 2.45 727 low gear ratio = 11.98 SLR to a 4.56 rear gear and swapped the trans to a Mopar 2.77 low gear ratio which made SLR 12.63 ratio.
Those two changes made that car a lot quicker and faster up
I was running that car in B/SA at that time and it had to weigh 3520 with me in it, NHRA had lower the HP factor on the 1963 low compression motors 405 HP due to them having a smaller set of carbs and a smaller camshaft than the 1964 M.W. low compression motors had up
Test, test and test some more to learn and hopefully go faster and quicker wrench up twocents


Cab, you could give George Carlin a run for his money.

Op, let me clarify, auto or manual? What is your current axle and low gear ratio.

As Poly mentions, with an auto STR greatly affects SLR.
