TURBHOE

i don't normally post cam threads but i have a guy at work that wants me to do some work. he has a 01 tahoe with a 5.3l. he doesn't tow or anything like that, and he wants it to lope hard. he has longtube headers, dual 3" exhaust and stock intake mani. he will be doing a 2800-3000 stall converter. i was trying to search to refresh my memory, but i cant find the info i want. if you run a good exhaust/lt but leave stock intake don't you want more of a cam with no split or very little between intake and exhaust? any way i was thinking of a 224/228 lsa110. i figure this would keep the dcr up and lope hard and keep the low end about stock or maybe better. i told him he may loose some low end he said ok cause he don't tow anyway.

Might check out the one of the Comp Thumper cams if lope is what he's wanting.. Prolly want to look at the smallest of the 3 since it's in a Tahoe.. Specs are 219/233 .553/.536 109lsa.

look at a comp LSr cam for 5.3 or a EPS cam for 5.3.

Thanks guys I'll check those out. Does the exhuast need to have such a split from intake if there is going to be a good exhaust but stock intake mani? I'm trying to refresh my memory is all.

That Tahoe is a heavy beast and the 5.3 will have a hard time getting it moving if you over cam it. I would go with something like a TR220. This cam has a pretty mean lope in a 5.3 and makes good power without pushing the RPM range above where the truck intake falls flat. The 224/228 is a great cam for a 5.3 in a regular cab or something lighter, but I'd keep the duration lower than that for a Tahoe.

I have a cam here that worked wonders in a 5.7 Tahoe locally. Its a 219/224 111. It was designed for a 5.3 but the guy ended up putting it in an LS1. Crazy bottom end and mid-range torque with killer lope. IMO, anything with a 224 intake lobe will be much too large for a 5.3 in a heavy vehicle such as a Tahoe.

it will work with out stalling and it's nice and torquey.

The 219 224 looks good or even the 219 233. But it would have to be on a 109 for sure. He wants the "lope". I'm across I'll wind up tuning he lope out of it. I did a 224 224 110lsa in a 4.3 and it idles like there is nothing in it.

Right on the money there.

My personal favorite is a Comp 218/222 113+4 camshaft I use for all the 5.3 Trucks/Tahoes. It works perfectly fine with the stock converter, makes gobs of low end power for towing, and is easy on springs. It's a fairly low lift cam (.540'ish) so you can use the cheap and reliable 02-04 LS6 valve springs. It requires a 7.425 pushrod on a stock 5.3 engine.

Damn. Now you guys have me wanting to put a cam in my truck.

Well I called eps and went with a 218 222 111lsa on lsg lobes. Should be fun. Going to run a new model 5.3 intake with a cable 90mm tb, long tubes with full 3" exhaust and a 3000 stall. Should run pretty hard I think.
