so if this is not what I am looking for what kind of stall do you guys recommend? I know nothing about stall and even what it is used for. Like I said I want a daliy driver and just more bottom end. anythig is better than what I currently have.
thanks
A stall basically allows the motor to get into the powerband of the cam faster. Picture it this way. If you had a 2,000 stall with the 0223 cam that was in your motor, and you took off from a dead stop at wide open throttle, it would be like taking off in a manual transmission car with the same cam in 3rd gear. The 3400 stall that was in the car was matched very well to the cam you had. It would be like having a manual trans and taking of in 1st gear at wide open throttle. I have the same cam in my 340 that you had in yours when you tore it down, so I know it is pretty radical for the street, especially an auto.
I think that this comp cams grind would better suit you.
CCA-20-670-4
233 intake duration/240 exhaust duration @.050"
280 intake duration/287 exhaust duration (advertised)
.474" intake lift/.474" exhaust lift
110 Lobe separation
power band 2200-6000.
Coupled with a TCI street fighter converter, 3,000 rpm stall speed. I would also put a shift kit in the trans, and install a good tranny cooler.
FYI, the current cam that was in your 340 had these specs:
248 intake duration/248 exhaust duration @.050"
292 intake duration/229 exhaust duration (advertised)
.508" intake lift/.508" exhaust lift
108 Lobe separation
power band 2800-6200.
I researched the stock 340 cam specs for 1968, and they are more agressive than the cam your engine builder picked out. I know you do not want to go overboard with a cam, but you still want some performance too. The stall that he picked out would work well with that cam because it's powerband was from 1300-5600. It would be a good combination, but it wouldn't have that much performance associated with it. It would be basically like driving a stock car. I hope this information helps you out.
