340 Cam Size

I ran that 292/508 cam for one summer with an HO 367,A833/3.55s and was glad to get rid of it. It really needed 4.xx gears with my 2.66low 4 speed. I was unwilling to do that. Otherwise from 5000 on it was a great cam. It just really sucked at take off,lol. Even with the 11.3Scr I was running. Not dissing the cam so much as the combo. She really flew once wound up., the problem was, 65mph was 5500 in second, just getting on the power. Course it spun the tires all the way there,lol. Was it overkill? Heckya!
In a 340 it's gonna want a lot of cylinder pressure or a hi-stall, and forget sub-4.xx gears, unless you have an overly-high for the street, convertor. This is a lotta fun for a week or three but the novelty wears off. A combo like this, seriously limits your "streetability"...... IMO.

EDIT; My booster ran fine with the 292/108. I think it came out of a either a 77F car or a 75 Dart. But I have manual trans and tend to blip the throttle on every downshift, which keeps the rpm up, and 11/1 compression is a lot of compression braking.
