So...LS?

I keed, I keed! But I freely admit as a relative youngster the LS is my engine of choice. It's nice to use the laptop to data-log, make changes, and see results as opposed to fiddling with a metered fuel leak (carb).

But going with the Richmond 6 speed over a T56? When it comes to cost, I have no idea. But I do know any variant of the T56 aside from the 1993 year will live all day behind your 427. The 1994-1997 its the LT1 style that would best work with your big block, but of course will require a bellhousing a most likely a hydraulic throwout assembly.

T56 Gear Ratios
1 - 2.66
2- 1.78
3 - 1.30
4 - 1.00
5 - .74
6 - .50

The ROD has many different options, but I didn't see the direct 1:1 4th offered. Perhaps I overlooked it. My cousin has a 70 C10 with a 355/T56 combo and the trans has the "mid-shift" conversion. It shifts flawlessly and I see no downsides to it other than price.

Good luck with the build!
