Cool all those will work on the renix right? Only reason I ask is because its listed for 4.0's up to 1997 but has a footnote that says "NOT FOR FUEL INJECTION"

ALL 4.0s are fuel injected. The older AMC straight 6s were not, but they were the same block. If their listing is specifically a 4.0, and listing it isn't for fuel injection, then you should consider not buying from a company that doesn't do any research.

Comp only listed one Cam for fuel injected 4.0s when I did my research. However, all of the cams will work in a fuel injected 4.0 if built properly.

What do you mean built properly? :hmm:

As in, you can't expect a stock motor to run with the most aggressive cam on the market installed. Mods may need to be done to sensors, such as the MAP, for improved driveability as well.

One problem with a cam thats too radical, is that the engine doesn't have much vacuum at idle, so the map sensor reads this as the throttle being open, and gives the engine too much fuel and will run real poor at low speeds.

I'm thinking of going with the smallest one of the bunch "improved gas mileage great replacement for stock,smooth idle" I'm not in any way trying to go with anything that us hot rodders would even consider "mild"

I got a hold of tech support at comp and they said the cams not for fuel injection have an LSA not ideal for fuel injection since they will not make enough vacuum, they wound up recommending the 68-232-4 instead,anyone familiar with how that cam performs? I told the tech I wanted something that would improve my mileage and torque and he said that's what that cam was designed to do.

Don't recall who made it, but the Baja BEast was an awesome cam in my Mexican 282 motor I put in my '83 Cherokee full size
