On a 'mild build' with 3.23 Gears, you want to stay at
2500 to 2600 RPM's.

And you will want 'cooler' trans-fluid temperature as well,
so replace the Stock Fluid Pan with a 'Cool-Pan'.

Thanks for the info!!

Remember that the 273/4 had as much torque as a 1972-76 318 and 5 more horse power than most of the 318's built.

Does that translate to bigger torque converter, do you know what that stock stall was on a 273/4? The trans i got was from a 65 i believe.

Don't forget earlier 273's won't take a later model torque converter so your probably gonna need a custom one anyways.

The block is a 66 and the trans a 65, is that going to be an issue?

Thanks,
