Cam or new rockers?

**DannyBoy** · 09-21-2014

I'm getting ready to do a top swap on my 99 grand prix gt, i was planning on getting 1.9 rockers with 105# springs, but then i thought about swapping my cam for the xp hot cam.

How hard would it be to swap a cam with the engine still in the car?

Also if i go with the cam instead, would i just keep the stock rockers and just upgrade the springs and retainers?

if you can get your hands on a cam id do cam over rockers any day. cam you can use stock rockers and 130# springs.

Would i be able to use the stock timing chain with an xp hot cam or am i going to have to upgrade?

You can use a stock chain just get a new replacement and a new dampener too.

Cam > rockers. And like smutty said just buy a new stock chain and dampener.

Thanks guys!

Any other info i need to know about upgrading the cam?

This will be my first time removing/ installing a cam so i just want to be sure i do it right.

There are a few write ups on putting in a cam. They should help you out.

It's pretty easy to swap one

Would i need modified retainers? Also what about the push rods?

Yeah i found this write up http://www.3800pro.com/forum/cams-he...-l67-tech.html

From what i read it doesn't seem that hard.

My only worry would be scratching the new cam when installing.

You'll need modded retainers. Push rods should be fine. Use assembly lube on the cam and you won't have to worry.

Ok thank you!

I was wondering what kind of head gasket you guys use? I can't decide on fel pro or cometic MLS.

Instead of xp hot cam i think i'm gonna go with the intense s1x cam, would 130# springs be fine with stock rocker arms to?

Cam is easy.. did it my garage, motor still in car... XP Cam... If I did it again I would pull the motor because.. well thats just 1000 times easier and I have the tools to do that

Felpros worked great on the 2 topswaps I've done. 130# springs on fine on stock rockers, I like the s1x from the research that I've done.

for a topswap just get the topswap gasket kit from zzp, will save you money in the long run. Ask me how I know lol
