So I'm waiting for Zcode to release his twin screw kit and don't want to spend any money on a TB or intake since it will be replaced with the TS.

My water pump and timing chain look original at 175k, figure that's a good enough excuse for a cam swap. Currently have a tuner, headers, air hat, and exhaust.

Going to keep the stock unported heads and kegger, so need a cam that will work best with that setup. For a 98 Grand Cherokee, weighs around 4400lbs with 30" tires and 3.73 axles.

New to domestics but if I understand correctly all I need is a cam and valve springs correct? I think I'd also need pushrods with a regrind cam but what if I used a new cam? Stock unported heads, don't want to take them off the truck. Not losing oil or coolant, maybe previous owner took care of it. Bought it from a charity so no idea.

Suggestions on where to buy the parts or what cam to use? I think the kegger falls on it's face after 5k rpm so no point in revving higher but I'd like the cam to also work well with a twin screw. Would like to spin it up to 6500 rpm with the TS. Since my jeep is a 2.2 ton pig with a 1st gear that will hit 61mph at 6500rpm and over 100 in 2nd, I think I need a cam that will move peak torque higher up, but idk.

Thanks for any help!

 

Guess I really cant answer the your question. But if I might make a few suggestion.... Did Zcode have a recommendation for a cam?

I agree your going to need to step up to a turboed cam to get the most out if what ever the conversion is going to be like.

But some heavy penciling needs be done, to get these combos straight...

As for choosing a cam.... I would use whom ever Zcode is working with a see if they might be able to get you in the ball park for that combination...

Keep us posted... I like these kinds of builds.... awesome..

 

Good idea, didn't cross my mind to ask him, thanks. Feel like I've been bugging him with too many questions lately. Hope he uses a tvs2300 instead, hard to find any sr4 superchargers anymore.

So he said his initial kit will be for those with the mx422 but he'll release kits for current whipple/mag soon after.

Suggested I talk to a cam specialist as he wasn't too sure either.
