Help with me a cam?

[Dezertxj88]

I still haven't picked a cam for my 4.2L stroker.

I'm building my stroker to be more efficient & run like I want it to. I'm thinking of keeping the stock cam, but also thinking of adding a cam that will offer a little more down low while loosing nothing up top. I love how my 87-95 single pattern cam can hold the power to 5300rpm, but I'd like more down low. Jeep will weigh around 5000lbs give or take a couple hundred all said and done.
Cruising will be around 1900-2100rpm pending speed. Motor is intended for a daily driver, expo/camping rig & its a 5speed. I'd like more down low to keep it idling over stuff, but also be able to hold the power to 5300rpm. What are my options here? Dino what do you recommend?


I was told about the Crane cam #753901T, grind #H-260-2? I was also thinking of installing my current 87-95 cam a few degrees advance to have it come on sooner? I know it holds power to 6000rpm which is not needed, so what about installing it at -6 or -4 vs the stock -8 degrees? Would that get me some more lower end?

That cam is the same spec as the Crane 753905 that I originally had in my stroker and it was a great choice (for the 34k miles that it lasted anyway) with a nice spread of torque. Anyone looking for more torque lower down the rpm range could go for the Crower 44243 but you could just keep the stock 87-95 cam and get similar results by advancing it 4 degrees.

And with the stock cam advanced dino what would my DCR jump to?

.060 over, 3.500" stroke, .000 deck, .043 head gasket, 14cc dish. 61cc combustion chamber. I'm getting 9.42 Static/7.15 Dynamic

If you advance the stock cam by 4 degrees, the DCR will increase by 0.25.

My new stroker is going to receive one of the wide-lobe MOPAR performace cams... Many of the aftermarket cams only have lobes that are 1/2 inch wide... Stock cams and the MOPAR perf. cams have wide lobes that are 11/16 of an inch... They also allow the use of stock springs, and seem to last a long time. The 228 or 229 Mopar cams are great for low-end grunt !!!

My dyno simulations did reflect that, but unless you're building a mostly or dedicated off road engine the stock '97+ cam was still better for the street, it's to bad they discontinued the "30AB" cam, it was better yet.
