My story on gearing. Have a 37 Buick with a 52 straight 8 that has 9 more HP and 20 more #/ft of torque than a 235 but also weighs a thousand pounds more so things are about evened out. I wanted to be around 2000rpm at 60-65mph so stuck in a set of 2.73 gears to go with the 350 automatic adapted to the straight eight. A torque converter is actually a torque multiplier so in the flat lands of Texas it was WONDERFUL but then I got into the hills of Missouri and it SUCKED. Glean whatever you want from this story.
I had a 1935 Buick model 46, three window coupe,
straight 8, 231, 93 HP, with a 4.11 rear.
I did not do this all the time but wanted to find
out how well a straight 8 could pull.
I could slow down to 12 MPH in 3rd and the car
would not shudder when I accelerated.
If I would of wanted to modify my old Buick and it
was possible I would of went with the stock rear
but add a 4 sp or 5 sp manual. Or better yet a new
Chevy/GM 6 sp auto with two OD gears.
What we could do if we had the money. Building things
to see if they worked out as good as we thought.
