@XOLATEM #1 I agree with you whole heartedly!! But hear me out...
The ‘79 C10 currently resides in South Dakota. Has a mild rebuilt 355 sbc with a small RV cam. Originally equipped with TH-350 and 3.42 geared 10-bolt but we got it with no engine tranny. Just a roller.
My ‘84 C10 (first vehicle) bought for $500 with a blown engine. Had a TH-350C and 2.56 geared 10-bolt. For Christmas dad built me a nicely warmed over 355 (camel-backs, pink rods, flat tops, 10:1, 215/220-ish cam) TH-400 and same 2.56 gear. I could boil my 1 and sometimes 2 tires almost at will. I had to buy my tires, so I was a good kid. Required 93 octane fuel (it loved Texaco’s additive). Crisp shifts, and it’d happily run 80.
I use to run between dealerships getting and delivering parts. I was offered new pickups all the time and turned them down cause my pickup drove so much better. More power, better shifting trans. It would smoke the offerings from Ford or Chevy (maybe not the lightning or 454ss) of the late 80’s early 90’s.
Rust took my pickup and it became a red neck trailer. Dads 79 got the TH-350C. It started slipping and dads friend owned a trans shop. He rebuilt the TH350 with a TH400 TC, and whatever else all for $700 in 2010. That’s dropping the pickup off and picking it up. We swapped 10-bolts to be more interstate friendly. (3.42-2.56)
the TH-350 shifts with authority. We have grossed 12,800 with the pickup and trailer hauling lathe and plaster with 2.56 gears and the pickup did NOT feel labored (I was driving).
Point is, we already have a solid TH-350. I don’t have a 700r or 200r, and I don’t own a 3.73 gearset.
My free options are...TH-350 or 400. And (2) 10-bolts in 2.56 or 3.42 gearing.
My dads driving days are numbered (he’s 80) and I wanna keep his ‘79.
I have (2) 6.2’s just sitting. I was thinking the low end, coupled with a turbo would be just fine for light duty and commuter use with the TH350/2.56’s vs a carb’d 355 up here at 7500’. Plus it’d keep me mechanical.
At 60mph with 350/2.56/29”tire it equals 1780rpms not counting slip. At 70 mph, 2076 revs.
I have been driving the 355/TH350/2.56 combo since 2008 on a semi regular basis and it’s peppy.
Any and all advice welcomed!!! Sorry for the thread derailment....again!!
