OK, I have a question, and I haven't quite found an answer. On a stock headed LT1 the CC503 is known as the biggest cam with the most useable powerband, so I bought one. Well, along the line, I got a good deal on a set of AI 200cc heads with the fully ported and geometrically corrected intake. However, I do not have a "matching" cam for these heads and I don't plan on buying one for this right now. Reason being, I plan on building a 383 in the near future and do not want to buy 2 $450 cams.

My question is, how will the stock displacement engine "act" with the CC503 and the AI 200cc heads? ie. will it be lazy; will it move or lower/raise the power band; will it smooth out the idle; etc...

I may just end up waiting until the 383 is done and just bolt them on there......but I kinda want to play now! Anyhow, please don't let this thread turn into a " you will need a stall, gears, suspension, headers, etc." thread. I already have a good idea on what I need, or already have.

Thanks,

Boltem on they will make good power with the cam.

you only really have to buy the cam once. if you buy the $400 cam now, then once you do the 383, you can just have it reground for about $100-150 (as long as it is a billet core, which Ai uses).

Thanks for the input, I do appreciate it, but that is still kinda my point. I am only wanting (and have the money) to do this once. A reprogram to the ECM is no sweat, (I have the resources to get that done) but having to buy parts over or having them fixed for later is not my intentions.

I am just kinda curious as to how this cam would react to better flowing heads. Has anyone done that before?

I would baseline the car now with just the cam (chassis dyno or runs at the track) then put the heads and intake on and get it retuned and re baseline it and buy a custom cam for the 383.

It's will prob be retarded fun with that topend and "maybe" give up 10 peak HP to a bigger cam. Build it, I guarantee it will perform.

P.S. I would run 1.7 rockers

I have a similar setup. I had the 503 cam on stock heads and it was a pretty good combo. I got a deal on some AI 195 heads and it still behaves the same at low rpm but it revs a lot quicker and the mid range comes on a lot stronger. I haven't done too much high rpm stuff as I'm still breaking in the clutch and it hasn't been tuned for the new heads.

Put those heads on you will have a very fun street/strip car. I don't plan on buying another cam until I rebuild either.

With all due respect snk-huntr, please don't reply to any of my threads unless you have something at least half way intellectual to say. I have read some of the other threads you have contributed to and I must say that I am less than impressed. Not to mention, I really don't want this thread to get locked.

Now, with that being said, I do realize that it may not be an absolute requirement to have the ECM reprogrammed for a head swap, but it would not perform optimally. AND, I also know that even a completely stock engine can benefit from a re-tune, let alone a modified engine. Enough about that...

To the rest of you that have posted, or will post later, thank you for the responses. Also, if you all would, please just ignore the replies that snk-hunter makes, as I don't want this thread to turn into a bitch-fest.

My heads came out a lot better than I ever expected them to, approaching your AI 200s. Meanwhile I had already bought the cc503. Looking back I might have gotten a LE 230/236 cam on a 112 with around .565/.570 lift to fit the heads better. However, on 1.6s, the 503 still helps create AMAZING power and torque up to about 6400 before it starts to drop off. And that's only at .537/.544 lift on 1.94/1.56 valves. Gregrob & the other guys are right, it'll still rip- throw it in there.

It sounds like you got lucky, these heads and cam should work well together-however, this is not always the case when you have wildcard heads/cam combos.

Guy that did them has about 40 years experience and did them by hand himself, along with my intake. He had a ton of nascar & circle track work last fall and it took him longer to get to my heads than he thought it would. He made my heads a pet project to make up for it. Hell of a nice guy in Fuquay-Varina, NC. Steve Ashworth. Spends a lot of time with you to make sure your goals are understood and will educate you where needed. I didn't know anything about him, but a trusted friend recommended him. So I have a set of heads that might make good use of a "bigger" cam.

OP should have a good result...

Is that your final answer?

Gregrob, in case you missed my previous post, I asked for it to be his "final answer" and I also asked everyone else not to start any more **** on this thread. I would like to keep this one on track.

Thank you everyone for you input on this too. I feel better about putting these heads on now!
