That 342 is definitely gonna want more gear.And that o/d has to go.
The ratios in that box are; 3.09-1.67-1.00-.71 with splits of 54%,60% and 71%
You will need 3.91s, at a minimum with that 3.09 low.. But the rpm drops are way to severe in that box for that cam of yours. That cam will want to hit at least 6800 in first to drop into second at 3672, with the power centered at 5236. The 2-3 shift will want to be around 6500, to drop in at 3900, with power peak centered at 5200. Your cam has not got a powerband that wide.
So the cure is to replace that cam, with something more suited to the tranny, or
To replace that tranny.
If it was mine to do, I would do both.But I also wouldna put a 342 into that 87 Ram; unless I could get the Ram down to 3400pounds or less......
