Thread: Camshaft Install

So my engine spun a rod bearing and since I'm rebuilding it I figure now would be a great time to install a mild camshaft.

I'm looking at the VS and the S1X.

What chain, lifters, and springs do you guys recommend?

I'm trying to keep this reliable and I have read that with 105# springs the dampener will wear quickly. So I'm guessing the rollmaster double chain set would be the best bet.

It's going to be a different answer everytime I ran 105s / s1x/ new stock chain and dampener/ 42s/3.0/oe-r lifters/ stock rockers etcZero issues


stock lifters are fine too. I just got a good deal on the oe-r

How many miles on the new chain and dampener after the cam install?

You mean the one I have listed for sale? 6 miles

I meant on the setup you have listed above

That sig is old I recently did a whole new stage 3 build. I had the s1x for a couple years. The dampener looked just fine

My setup is close to his ^. S1x, 105s, stock lifters for me, stock chain and dampner. Close to 8k on the install now, no problem. No need for a double chain with only 105s.

I've put about 2k miles on mine in the last 5 weeks. Runs great, sounds even better with the cam, and just keeps pulling.

Xp, 105's w/titanium retainers, stock lifters/pushrods/rockers, had a jp dr but tossed it for a new stock chain/dampener when installing engine into my bonne. I also don't rev past 6k, not much power up there anyways with my setup.

Why rebuild the motor? why not just get a JY one. if you rebuild, make sure you bring the rods and block to a machine shop and have them check for alignment and make sure the rods are perfectly circular...

Which alignment are you talking about? I took the block, rods, and pistons to a machine shop and asked them to check the rods, they told me the cylinder 1 rod is trashed(the one had the spun bearing).

Make sure the block is still square. The 3800 wears odd and the rods will become oval over time, if you press a round bearing into an oval rod it will spin again in less than 1000 miles. The crank can also oval overtime. Generally its smarter to just get a junkyard block and drop it in unless your going all out forged, Blueprint, balance etc.

Wouldn't a junkyard block also have those above mentioned problems? My block only has 138k on it. I will ask the machine shop to make sure it's still square though since you suggest it. Should I buy a new set of L32 rods due that issue too or just have them checked? As far as my crankshaft goes, it was trashed when the rod spun, it took too much off the number 1 journal.

Yes a JY motor would have the same issues; however they happened slowly over time and your not trying to shove a round peg in an oval hole.

So it won't just pop. I out 60k on a JY motor at 600+ whp.... They last lol trust me.

So you guys are pretty much saying my block is probably trashed which caused this issue?

Thanks but I think the XP may be a little more aggressive than in looking for. Wanting to keep some gas mileage as the car was a daily driver and will be once its back up and going. I'm assuming though all the parts you listed would still work for a VS or S1X cam.

Dunno. The rods wore oval and if you just press in bearings they will spin. Get them checked and make sure they are perfect circle...

I had an XP lost 1 MPG. Go XP you don't regret it, great power increase, or s1x same thing
