20 cubes at 2000 stall is easily worth more than ~5% Gear change so from say 3.91s with a 340, to 3.73s with a 360
said another way, with the same rear gear, the 20 cubes is worth easily 400rpm stall, say from 3200 on the 340, to 2800 on the 360.
For a dual-purpose machine, these things are important.
You can easily punch an early360 out to 4.04, so that argument don't hold water. 4.04 x 3.58=367 cubes; now yer 22 over
4.07x3.315=345
My 367 with 505gram hypers goes 7200 anytime.The Hi-C factory 340 slugs were 745 grams.......IIRC.... They can both run 318 bushed rods.
