torque bump-stick for a 250
I have a built 250 I bought from a guy who apparently had it built to the specs. of a hot rod article years ago, but he has since lost most of the documentation. I am a little concerned that the cam is going to be more of a high end RPM cam, and be of little use in my 3/4 4x4. Can anyone recommend a good torquey cam for the 250, I am happy with my stock setup now, but it needs a rebuild, and a rebuilt engine like this with all the goodies it had was WAY less than just a basic rebuild on my stocker.
I am looking for something with good low-end torque (looking at putting 35's on to replace my 31's) but I would still like to take advantage of some of the high RPM balancing that was done on this motor.....can I have both?

Re: torque bump-stick for a 250
Call Comp Cams and see what they reccommend then see if Summit has an inexpensive version that is close to that duration, lift and separation angle.

Re: torque bump-stick for a 250
Contact Crower and ask them to build you a "Baja Beast" for an I-6. This is the modern day version of their legendary "Baja Torque Master" that has been in existance since the late '70's.

Re: torque bump-stick for a 250
ttt anyone have any specs on the baja beast cam (in particular torque curves, redline, etc?).
More important, has anyone run a 250 with a setup like that and 4.10's turning 35's?

They even have a worksheet you can fill out w/your info re: your truck such as weight, gearing, tire size, engine specs., intended use etc. With all of that info they can grind you a camshaft to your satisfaction.
