Ok,

Well I made a thread a couple days ago talking bout my truck dieing and it being the timing chain.. Since I'm in there, I was thinking of doing a new camshaft.

What I'm looking for is a low-mid camshaft I can put in without machine work if possible. (If need be I'll consider but I'd prefer not to.) I've heard / searched this and seen people talk bout the comp cams. But there .500 which i thought you couldn't go above .480

So what would you install in your truck to give you a low-mid with no machine work needed. And this will be my first install on a 4.3L what all would I need to install this camshaft. (As in parts please, if possible PN# and place to buy)

I know the specs are

Factory 4.3L Cam Specs
* '96-'00, VIN W, w/ balance shaft
- Lift (I/E) - .415/.429
- Dur @ .050 (I/E) - .191/.195

I went through this same ordeal a couple months back. Did a lot of research, came up with more questions than answers, but I'll tell you what I found that may help you out.
You're correct on the stock specs and max lift of .480. Yes, Comp doesn't make a cam that will fit directly in with no other work. I was told Comp would do custom grinding at no extra cost, but I can't confirm that.
I found Crane Cams makes cams that will fit our trucks: Catalog
You can purchase them through Summit: Summit's website
Lunati also makes some, but they are not listed on their site. Only cams for older 4.3s with flat tappets (ours are hydraulic rollers) are listed. However, I emailed them and they said they could put any of the flat tappet cams listed on a hydraulic roller core with identical specs. You'll have to email them for the price. I believe it was $300 something. Much more than the tappet cams cost. I never did figure out why ones for our trucks cost so much more. Maybe someone else could help me out on that.
That's all I've got. I finally said screw it and have decided I'm just going to get my PCM tuned for a little more low end and mileage. Hope this helps.

Thanks.

Anyone else have any camshaft pn# i can use without machine work?




I'm looking to install a camshaft and get a hold of wait4meprofrormance and do a TM tune. Anyone know the cost of a tune?
