big66440 Posted December 24, 2011 Author Share Posted December 24, 2011 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" Link to comment Share on other sites More sharing options...
Geonovast Posted December 24, 2011 Share Posted December 24, 2011 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" Â Â 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.

87Warrior Posted December 24, 2011 Share Posted December 24, 2011 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. Link to comment Share on other sites More sharing options...

87Warrior Posted December 25, 2011 Share Posted December 25, 2011 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. Link to comment Share on other sites More sharing options...
alleydog Posted December 26, 2011 Share Posted December 26, 2011 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.

big66440 Posted December 27, 2011 Author Share Posted December 27, 2011 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" Link to comment Share on other sites More sharing options...
big66440 Posted December 27, 2011 Author Share Posted December 27, 2011 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. Link to comment Share on other sites More sharing options...
carnuck Posted December 27, 2011 Share Posted December 27, 2011 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 Link to comment Share on other sites More sharing options...
