That's what "recommended stall converter rpm" means. That "2500+" stall speed torque converter recommendation says it all.I had the same problem with the GM 350/290 hp engine. It was a two-lane terror. The 50-90 times were incredible. Getting off the line? Not so much. All the hot rod guys will tell you, horsepower gets the headlines, but torque is what you drive. And those cam specs you have are close to the cam specs in the GM 350/290 engine. Yes, vortec heads help a lot, but still....... They both completed the quarter-mile in the low 13s, in darned near a dead tie. In contrast, the 1970 Buick GS 455 Stage 1 was only 360 hp, but it had 510 lbft of torque at a low 2500 rpm. It was a quarter-second slower than the Chevelle and the Hemi Cuda in the quarter-mile, but it would positively smoke both of them in the 1/8th mile. Gonna race in circles? Hard to beat that hemi. Drive on the street? I'll take the Buick.What I did was swap out the cam in my 350/290 (yeah, the cam I paid $500 extra for over the 350/260 hp base crate engine) and put in a torquer cam. I gave up a little horsepower, and there's no "choppy idle", but I am getting over 420 lbft of torque at 2500 rpm. So my cam is in the middle of its torque curve at the same rpm that your cam specs say is where your torque curve starts. When you think about it, it makes sense. Unless you are a circle-track racer, you are almost always in the 1500-3500 rpm range in normal driving; that is, in the lower half of the working rpm range. And "choppy idle" means the engine doesn't like to run at low rpms.I just ran a dyno simulation on your setup and ran through some choices on a cam ............
