Hi,
I'm working on a 1992 22RE. The truck is a 1990 4x4, reg. cab. I've got the engine torn apart to replace the head gasket and timing chain. I've been thinking about putting in an RV2 camshaft from yotashop.com. I have never changed a cam before.

With the engine already apart, is installing a new cam as simple as basically unbolting the old and replacing it with the new, then adjusting the valve clearances when I put it back together, or is there more to it? I also have new head bolts to use when I reassemble.

Thanks

No it really is that simple when its torn down like that. Now I use Delta Cams regrinds so far so good, much better than stock profile.

I have a 272 cam going in the new engine, and I think a 260 in the other truck. The one really does idle nice. The 272 is for play. You really don't want to stray far from a good idle. Radical profiles are for competition, leave them at the track.

That's good news -- thanks. I was just wanting to make the truck a little more fun for everyday driving. I agree regarding idle; a good idle is important. Which of those two cams would you suggest (260 or 272)? Thanks

The 260 is a hoot, fun to drive and practical. The 272 engine is sitting on an engine stand, I should know by winter. I expect the 272 to be more of a hassle due to higher lift and duration and behave more like a muscle car.

Great - thanks for your help!

I ordered a cam last night, a Delta 272. When I install it, do I need to use any special lube, or just engine oil? I know I've heard of cam lube, but am not sure if that's necessary.

Thanks

Yes; there are special cam lubes for solid tappet cams like the 22re series I got mine from Grumpy's place on ebay. But you can use engine assembly lube, red sticky stuff.

Ok -- Thanks again

A shameless plug for Delta cams, got a bent cam from them a while ago. Well they just replaced it with no hassles or fuss. Just got the replacement Fed Ex today.

Kudo's for them!

Good to know, just in case.

I have this week off work and am hoping to get a lot done on the truck. So if I swap the camshaft, put the new sprocket on it, and install the new timing chain, how do I know I have the new cam in the correct position? The crankshaft is still at TDC on the compression stroke. Thanks again

Colored links go over the dots on the cam gears. Check my photo library for pic's. Just finished mine, tore out a camshaft bearing cover bolt. Got lucky and got it fixed.

Thank you, didn't realize the crank sprocket also had a marking. Speaking of the crank sprocket, I found that the old one was missing a few teeth! Nice
