Hey guys,
I'm in the process of re-building the 235 engine for my napco suburban and am driving myself mad trying to choose a cam.
The three choices I'm looking at are:
Stock 235 cam: 168/170 int/exhaust @ .050"
My experience driving around with this was good... with my big tires, tall 3.38 rear end, and really wide gaps between ratios in the sm420 I am forced to lug the engine in a lot of situations (ie. when shifting from 2nd to 3rd especially uphill, or just going up short hills in 4th). Even down near 1000 RPM this cam has no problem with wide open throttle.
Stock 261 cam: 184/189 int/exhaust @ .050"
Tempted to buy this one, hoping to unlock more power in my ~2100rpm highway cruise mode
But will I loose torque/drivability in the 12-1500 rpm range?
Bulldog cam: 212/218 int/exhaust @ .050:
Am I just getting greedy here? Is this going to trade all my lugging ability for crank pounding up above 3000rpm?
What cams do you guys run, what type of driving, how well do they lug? In my opinion the 235 sounds like it wants to explode by the time you get to 3500rpm, what do you guys think?
