10.5LT1

I lookin to build a mild 12.0-2 street car. What do you guys that run these heads think? Do you like them? And should i look for a larger cam i just got a CC503 is that to small?

What's your current set up??? With a full bolt on LT1 w/ this A.I. package you should def be in the 12. I'm leaning more towards the 190cc myself with Advanced Induction.

I want to stall it but im not sure what size... With properly ported heads can i get these same results?

I like the 190cc but they seem like they are alittle more than what i want to do with the car. I was thinking that if i got too BORED! i'd spray it!

I don't know of too many guys running the 185s. I run the 190s and they get my pig of a car to 11.9s in good weather, I do take some weight out of it but nothing too spectacular as the bumpers, ABS, AC etc. all stay intact and this with with a mailorder tune, mechanical WP, street tires in front and even lightened it is a good bit heavier than a full weight f-body.

The heads package comes with a cam, it wont be a lot "bigger" then the 503 but will quite well. Off the shelf stuff is compromised to account for most guys not picking cams very well. The 503 is decent but leaves room for improvement.

I agree with Caprice on the cc503 thing, the most optimal cam for Ai heads would be an Ai cam.

I don't see a stall converter on your list? Definetly without doubt need to have one of those in the A4. A good setup cam-only A4 car at full weight can reach or get very close to your goal so with one of Ai's heads/cam packages I would say you would easily reach your goal assuming everything is set up right and the rest of your setup (stall size, gearing, etc.) works with that.

The 185's are definetly on the milder side of things but I would just spring for the 200's but thats just me. The cam and gearing/stall size will effect the comfortness of driving more than the heads. But like I said, even the milder 185's should have you at or beating your goal assuming the car is setup right.

I would call Ron at Ai and talk to him b/c he will be able to steer you in the right direction for you.

Good luck getting someone on the phone at A.I. I've called 3 times and left 2 messages... going on 2 weeks now with no call back.

Thats pretty much why I went with Lloyd Elliot over Ai because their communication sucked and it really pissed me off plus Lloyd was always a call away when I was installing everything and needed help. Anyways Ai does good work from many results I have seen so dont get me wrong I am not bashing them one bit.

Yeah maybe I should call it good with a 150 shot

I'd just spend the extra $200 and get the 200cc package, personally. You're going to definately want to stall it, no doubt about that. You might think about throwing some money at your suspension shortly after the install. Also, make sure you have someone good tune it. With all that you should have NO problems meeting your goal.

I called them as I posted this with a question about my motor build. Ron answered within 2 rings...

I would call them and see what they have to say about your setup. My personal reccomendation would be a set of 200cc heads with a mild cam spec'd to your goals. A set of 185s would get you there, but I build cars with the mind set of, "while I'm there."

Ron and Phil get busy. However, they always get back to me and believe it or not I've talked to them on weekends too.

I now have the AI 200s with an AI custom cam much bigger than CC305/ 503 and I'll use them again. (AI 200s were my second AI build, I used to have AI 190s , stock shortblock and a sensible cam. (it was good performer too but the car didn't scare me, hence the hairier rebuild once I finally roached the stock short block.)

As others have mentioned don't forget about a quality stall converter.

Good luck on your build.

i have been planning on stallin it. but im unsure of what size to go with because i have not decided on cam size. I want to keep it truly streetable the 200cc is way too much for my plans!!! but the 190cc may fit a little better. i have a high mileage stock short block i dont want to run too many RPMs through it with a huge cam. What size stall should i go with if i run the 190cc kit?

The 190cc kit is no longer available. It is still listed on the website for comparison sake.

Only the 185 and 200 kits are available. You might find some 190s forsale used though. My car and the times in my sig. are with 190cc heads/cam package.

A well set up car can run 12.0s with the CC503 on stock heads, plenty of people have done it over and over again with cams very similar to or smaller then the CC503. So I imagine throwing heads in the mix, your goal is definitely attainable. Really comes down to what the car weighs and what it can sixty foot, those are big factors on getting an et. A good converter, correct gear for tire size and tire really are what you need to look at. You really dont need ported heads to run a 12.0-12.2

Same here we talked a couple of days ago E-mail or Phone I never had any prob getting ahold of Ron.

I think im goin to go with the 185cc. I have a high mileage stock short block i would have to run a larger cam MORE RPMS! I looked at the dyno sheets for the 200cc and the shift at 7200 RPM way too much! Does anyone know the spec on the cam that comes with the 185s

BizZzatch350

iTrader: (33)

They don't advertise specs, I wouldn't worry about the short block, if its gonna go, its gonna go. I have seen these cars get spun bearings with hot cams just I have seen 847 cams. When you have the motor just inspect the front cam bearing for wear.

RPMs depends on the cam selected. With a stock shortblock you will want to keep rpms lower so they will spec a shorter duration cam. They had guys turning motors over 7000rpms with the 190cc heads too, even on strokers.

10.5LT1

I was goin to change and go with the 190cc but they dont make it anymore. It would be overkill to run a huge head with a small cam to keep the shift points low. How much more power do you think the 200cc would make over the 185cc with a CC503.
