True, but I'm in college right now and 10hp is not worth $250 for the rockers and $50 for the pushrods + studs and all that other good stuff...

What do you think about this cam:

63-07-467-8 Comp Cams XFI LT1 Camshaft, 230 / 236, .576 / .570 113 LSA, Strong mid-range and top end power. Headers, exhaust, gears, converter, computer tuning recommended.

VS. the cc503 (i think these are the specs)

Comp Cams "Extreme" LT1 Camshaft, 224 / 230, .502 / .510 112 LSA, Strong mid-range with good top-end power. Heads, Headers, High Stall or M6, Gears, Computer Tuning Required.

The CC503 should be a little milder on the street compared to the first one you have posted. I'm sure the power gains will be pretty close to each other.

You do have an electric waterpump? You mentioned a Cloyes Timing chain and for that you need the electric pump.
The 224/230 would be better over the 230/236. I use to have the 230/236 cam and it never has put down that great of numbers. A few guys have made about about 345-350rwhp with stock heads with the 230/236. My buddy put down 340rwhp with his 224/230.

The Lunati chain is known for being junk.
I don't understand the expensive push rods and new lifters because you're on a budget but then you're going to run stock rockers arms.

2000GTP

From what I've heard, the Lunati chain uses GM gears and may very well use the same chain as well. Considering how much a stock GM set costs, versus that, I would say it is not a very good buy.

You don't need new lifters, and if you're on a serious budget just throw a new OEM chain in there and call it a day.

Your list is missing the 1.6 RR's.

BradcTA

Isn't it very risky to run the old lifters with a new cam? I guess I can do without the pushrods, but I afraid to take a chance with the lifters. If one of them collapses, I'll have to tear the whole thing down again! Are the lifters on the LT1 better than the lifters on older SBCs because you always had to replace them.

Can you run a new chain on the old gears? Where is a good place to buy the GM chain set?

The rockers comp recommends for the cc503 are 1.5 rr. What 1.6r would work?

Dave1980

Well your talking all this stuff about how your on a budget, so dont do the lifters, as it is not as necessary as your thinking for these 2 cams. How many miles are on the car???????????

You can sit here with what if type scenarios all day long. What if you got in your car tomorrow and the motor spun a bearing after the cam install? I know you dont want to do unnecessary work, but your going to have to create a what i can afford list and stick with it. From what im gathering, I would hold off on a cam install for you and do more reading what everybody has done in the past and the problems they have encountered.

Why are you asking if you can run a chain on the old gears if I just told you I had been doing it for a year at least? Get a cloyes chain or cloyes chain set. Local auto parts store has this chain.

Sorry if im being pushy, but just trying to help you make a more knowledgeable decision.

Again you need to go after this cam install strategically putting in what you can afford while you have the car apart. (Timing chain set, lifters)

Add what you can put in later underneath each valve cover. (Rockers, Guidplates, Pushrods)

Comp recommends 1.5 rockers because that is what their specs are listed at. You are making the cam Bigger by using 1.6 (usually a good thing) (lift #'s go up)

I hope all of this is helping

OBTW the bigger the cam gets the more likley your going to need more parts to make it work safely

Can I run the cloyes chain set with the OEM water pump or does it have to be electric? The car has 107K on it.

Dave1980

It can be ran but it must be the single chain type and not the double. I would see if you can get the chain and 2 cog gears that go with it. It all depends on how bad your set is on the car. The chain can stretch over time, and the gears teeth can wear.

My chain has suprisingly little stretch to it, at 80k.(when the cam install took place) I still replaced the chain.

If you can afford it man get lifters, however I think you will be fine. I have at least 108k on my car now, and no problems on stock lifters with the 503.

Javier97Z28

Yes, you can run a new chain with old gears.

No, it's not risky to run the lifters. You've got the old flat tappet mindset going on. Wear pattern is not an issue with roller lifters. Just reuse them. I was fine for a very long time on my 70k mile lifters.

Comp doesn't "recommend" 1.5 RR's, that's simply the way the cam is advertised. Everyone and their mother here runs 1.6 RR's.

There's alot of experience on this forum, listen to it.

If you are that paranoid about lifers you can get some new LS7 lifters from gm for around $100.

Just wait till you can do it all at once...no sense in half-assing it.
