Cam Question
Well I'm looking at putting in a LS6 Oil Pump because:
1. I have a 98' LS1
2. Has 130k miles on it
3. After reading about "Shaddy's" problems I'm worried mine will go out soon with all the stuff I've been doing.
So since I'm down there and really hate doing the same work twice. If I was to get a Cam like TS&P MS4 could I still run it on stock LS1 heads?
I know I won't get the full power gains until I get better heads and I can't afford to do H/C swap now (I already have a LS6 Intake). I just want to know if its better to just wait to put the CAM in with the heads or go ahead there's nothing to worry about.
I also know I would need to change push rods. What else would I need to be looking at? Benefits of a beef up Single Timing chain vs a Double Roller Timing chain?

Are you an A4, if so you should get a stall if you don't have one. Also you will need better valve springs. I would get a ls2 timing set. The difference between single vs. Double is basically the double is two chains whereas the single is only one. Double rollers are stronger and last longer but also don't always clear the oil pump depending on the pump. They will clear the ls6 oil pump for sure though.

What are your goals with this car? Be honest with yourself, MS4 is a very large camshaft for the 346 LS1. It will be very good high RPM performer, but will not make the mid range power of a smaller, more suitable street camshaft. If its a track oriented car, go with it. If not, do some research before going with a MS series camshaft. Plenty of people do cam swaps and leave the heads untouched, will it leave power on the table? Yes. Do what you can afford though.
You told me you read the Camshaft Sticky up top, that has a break down of what parts you need. I personally run the LS2 single chain, as does a large number of others. Single will be fine, there is also some timing chain comparisons in the sticky I believe.
Furthermore, the MS4 is a top end performer no doubt. LS6 intake will work, but the FAST starts to shine up top, where the LS6 starts to fall. See where I'm going with this?
There are single chains that I would trust more then a double, I would still stick with a nice single chain.
Not sure who told you that, 98's have some flaws, mainly PCM limitations. OP won't be touching the limitations. Whoever said that, is wrong
Stage III refers to the amount of port work performed. That's not how it works. Stage I heads are not stock runners , whereas Stage III is something crazy like a 225 head. OP, if heads are in your budget, look for a nice used set of AFR's. AFR 205's can be had for a nice price used, and are arguably, the best performing head for the LS1 street/strip car.
The sticky will show what is needed for a cam swap, and LS1howto.com is a great website to get you up to speed for the swap.
The sticky also touches on the little things that will add up in $$$ as you add power. Clutch would be the first that comes to mind. Factor in a chassis dyno tune also.

I thought stage 3 where ment for bigger bore motors? That motor is going to feel like a dawg down low with that cam and some stg 3 heads..... You will need gears to make up for the lack of low and mid range from this combo

Shady what cam would you recommend? (for now)
I would say 60/40 street/track plans. Plans are in the long run mid 400rwhp range. Planning on a LS6 in future to help get to that number.

Why not a ls2 for your future plans? The ls2 would easily get you to where you want to be for power.
I wasn't saying double are better. Was just saying they are suppose to be stronger because of the double chains but I also personally would get a ls2 single timing chain.

Actually we were just having a discussion about this in another thread with Basham. Interstingly we were talking about HP between the LS2 and the LS6 crate motors, when Frost mentioned he sees the LS6's put down 400+ RWHP on his dyno,,,while the LS2's with same mods make 370-380 RWHP.
The LS6 crate is no slouch by any means.
Exactly why the LS6 is a more popular swap as well, since the LS2 requires harness adapters, reluctor wheel adapter box, etc..

FBJ,
Do you know the answer to the LS2 timing chain question from my post 16?
-
01-27-2011, 11:33 AM #19
just the chain.....check around....should be a few bucks cheaper than that unless they've gone way up since I did mine.
At a minimum you'll want pushrods and springs. You can buy a "cam package" that will have everything in it.....$599 for 918 springs or $699 for prc double's.
