Torq converter help
 

I have a 68 K20 with a 350/th350 combo. I picked up the transmission without a torque converter and needing help on the right one. I like the B&M converters but curious as to what stall. Here is what I’m working with for a cam and gear ratios.

Lift
.450 intake .460 exhaust
Duration
222° intake, 222° exhaust @ .050" tappet
Centerline
114° ATDC intake, 114° BTDC exhaust
Rpm Range
2000-6000

Dana 44 14 bolt
4.10 ratio

Also any insight on how you decide this information. I’ve always just went 500rpm over the low end cam range but I know weight of vehicle and gear ratio play a factor. Thanks

mostly street driving ???

the 500 over seems fine, the gearing and tire size will feel like a slightly higher stall.

all depends on how you want to drive it....we have a very nice Chevy SS driving around (fully built), probably has a 3500 stall, and it sounds nasty at idle...but in town driving it sounds ill due to the converter stall. it is not street friendly at all.

Yeah mostly street driving with the occasional snow fun in the winter
