This cam with TBI?

[sled_dog]

I don't claim to be an expert about cam compatibility with TBI but this camshaft seems like it simply would not work well with TBI. Am I incorrect?

A friend is puting a new 350 in his 1994 1500 and he is using that camshaft. I just discovered this last night and after looking it over I think it is too much cam for TBI. I'm basing that on duration at .050, seems like it is just too much duration. I realize lobe seperation plays a large part but I'm being too dumb to figure that out by the cam card right now.

216* duration is too much IMO. The stock chip does not like durations over 214*. I am sure you can get a new chip burned for that cam tho.

Crane Powermax 2030 would be a better cam if you dont want to get a new chip

thought so, thanks

I would say depends on what else he plans on doing, like mentioned if he doesnt want to deal with burning new chips then dont do it. But I have a cam very similar to that in my TBI 383 but I also have world product heads, holley intake and TBI, and of course some chip modding. Mods like mine did not require much work to get it to run decent, I still need to really dial it in but with so many other things going on I havent had the time to really play with the chip the way I want to.

Not to highjack, but with TBI whats your thoughts on this cam:

Intake Duration at 050 inch Lift:194
Exhaust Duration at 050 inch Lift:204
Duration at 050 inch Lift:194 int./204 exh.
Advertised Intake Duration:252
Advertised Exhaust Duration:262
Advertised Duration:252 int./262 exh.
Intake Valve Lift with Factory Rocker Arm Ratio:0.398
Exhaust Valve Lift with Factory Rocker Arm Ratio:0.420
Valve Lift with Factory Rocker Arm Ratio:0.398 int./0.420 exh. lift
Lobe Separation (degrees):112

larger displacement will get a better vaccum signal with a larger cam. That is a consideration with the duration as well.

Re: Mouse
Looking at the numbers. That cam should work fine with TBI. It looks like a fairly mild cam that will give very good lowend torque. Should work with the stock chip.
What cam is that one?

 

[mouse]

Its a mild Summit grind - I think part number 1101. Its what I've got currently, and I should have the new TBI roaring to life any day now.

Call Crane or Comp Cams, their tech dept is excellent, and can dial you in right the first time.

That cam will be fine with the TBI system. You will need a chip to get the most out of it.

 

[Thunder]

Yup. A chip will make the most of it. And I bet you can fix him up with a good one.
You guys ought to talk to Mark he knows his stuff. Plus he gives CK5 members a discount
