my 904-2800 was rated for a slanty.
It stalls a lil higher behind my stock 140 psi, 318 but I gotta tell ya, it's just right..
It stalls slightly different with every gear I run it, highest with 2.76s and lowest with 4.30s, but not by much cuz the stock-cam 318 seems to make about the same torque anywhere below 3000, lol. The car wears 295s in the back, with 10 x 2 brakes, 15/16ths WCs, and with zero proportioning; so the brakes can hold anything the 318 can dish out.
But it still flash-stalls a lil higher when the big TQ starts moaning, lol.
-------------------------------------------------------------------
Even the early 340 was never known for it's bottom-end torque, not even when it was rated 10.5 Scr, and I've never had a lo-compression model.
Notta chance would I run less than a 2800 flash stall, in a stock-cammed/stock cylinder pressure 340, on the street.
The less pressure it makes, the more stall I'm gonna run.
The 9/1- 318 made about the same rated torque as did the 10.5 rated 340, except the 318 peaked ~800 rpm sooner. Consequently, taking off with a 340 with a 2400stall, will feel about the same as taking off with the early318 with the same convertor, gear for gear, and pound for pound, assuming no tirespin; with the 318 possibly jumping out, off the line.
