I had the cai, lt's, 1.6 rr, and cc503 and put down 330rwhp on a mail order tune with my old lt1. It was pretty choppy too.

Oh NO! you definatly need the stuff both guys listed. Im not sure about the timing chain though. I dont think you NEED to upgrade it, but if your engine has higher miles it would be something to go ahead and upgrade since you are already there.

Is there a resonably priced LT1 timing set part number? The ones I've come across are like $350.

Yes you can, and if you go the cheap route with no guide plates then you wont need the longer 7/16" ARP studs, instead you will need to get the Self Align rockers 3/8" stud.

Do not run Self Align rockers 3/8" stud or any Self Align rocker for that matter with guide plates, if you do you will have metal shavings all over (a big mess!)

I just replaced the chain itself when I did my cam swap only like 20 something bucks

as for a ghetto parts list, here's where I come in

-USED CC503 $130 shipped
-NEW Crane 10308-1 Spring Kit $180
-NEW Comp Magnum SA Rockers $170
-NEW replacement timing chain $20
-NEW Comp Hi-Energy 7.200" Pushrods $30 (optional)

then of course you got gaskets, tune, fluids, etc.

LT4 timing chains only work with LT4 sprockets. Also want to get the Trick Flow guideplates because many times the GMPP's have a couple that are not hardened in the set.


I use to run the cc503, here is the parts that I recommend:

-Crane 10308-1 Springs
-Comp NSA Pro-Mag 1.6RR's 7/16" or any other RR that is NSA and 7/16".
-Trickflow Guideplates
-ARP Rocker Studs
-Trickflow Hardened Pushrods 7.200" (Assuming your heads were never milled etc.)
-Go to your local Chevy dealer and order stock valve stem seals
-New stock LT1 timing chain
-GM LS7 Lifters

I never did a before and after dyno but I picked up about 6mph or so from the cam, rockers, tune. The car trapped 110mph through my automatic at a 3700# raceweight at the time.

well he said he has an A4 so you would want to get a stall to go along with it and if your tranny has high mileage you will need to rebuild it..then you will need a good tune so it runs right..you would think putting a cam in would be pretty cheap but its really not if you do it right

I know this thread is old but I have a question. What will happen if I run the cc503 without the roller rockers? I understand it's better to but money is tight and fixin it up slowly

buddy of mine put down 359/354 with stock rockers on a stock heads and cc306, I was surprised as hell to see that number. madz28 mail order tune no less, A/F was dead on though. Am i saying run the stock rockers? No, but I doubt it will kill more than about 10 hp.
