In the future, id like to build up my camaro further w/ a 224R cam. my question is, w/ full bolt-ons and a 224R cam, can i reach my goal of 400rwhp without porting the heads or getting 243s? Bolt ons being 25% underdrive pulley, lid, ls6 intake + ported tb, 1-3/4" longtubes, catted-y and no muffler. The powers gonna get put down thru an A4 and 10-bolt rear.

Autos wont dyno as high as a manual, so take that into consideration. But some nice LS6 heads from TEA or WCCH and that 224 cam with a 3600 stall will be a nice combo and be fun to drive.

another somewut unrelated question is- I would prefer to keep the stock stall/not much higher than stock so would i be better off sticking wit a small cam and throwing on some stage 2.5 ls6 heads to reach my power goals?

Be hard for a stall converter car to get past 400 cam only. How fast do you want the car to go?

I'm really looking for a very stock-like behavior ride and idle wit a good boost in power that i can use around town and still get solid gas mileage. This really isn't for racing at all, just some spirited driving here and there

My buddy's car made 400rwhp with about 4.5 psi on an old school vortech, non intercooled, supercharger and full exhaust. Old superchargers are getting cheaper and cheaper in the classifieds here. Just something to consider, but many people have made 400rwhp without head work, yes.

A 224r full bolt ons and unported 243 heads will net 400 easy. Now if you dont want to buy new heads, send your stock 241 heads to AI and have them work their magic. Their 241's with nice cams have produced very nice numbers lately

My camaro is a 98, so would the 853s even be worth sending out or would i be better off wit untouched 243s?

No you will not make it, If you made 360 id be shocked

Camaroking1996

If you go with the 228r cam and fully ported 853's I could see well over 400. The 228r will drive the same as the 224r but make slightly higher numbers.

If you want 400 RWHP through an A4 you will need ported heads. Especially since your stated goal is to get there with stock like driveability.

Mike Morris

Exactly. People are forgetting A4s with converters don't dyno high at all. If you want a nice punch in power get a cam,converter,bolt ons and you will be pleased.

Don't get caught up on dyno numbers. If that's your "thing", then throw a ******* donkey dick in there and you'll have your dyno queen. If you want a great street car that can hold it's own at the track and likely beat the **** out of other cars with a cam that is way too big in it, then go with the 224r, 228r or 224* 228* cam with some nice heads like AFR, TFS, PRC.

Ported/milled heads needs to be on you list to see > "400".
Id also highly recommend going with at least a 3000 stall TC, even with a stock or small perf cam.

Don't ever mix horsepower and good gas mileage together again.. It just don't work like that my man.

There are plenty of guys making 450hp and up and still making great horsepower. Its all in the setup and tune.

400rwhp on catted y pipe with a 224ish cam through an automatic isn't going to happen on a realistic dyno.

Honestly the converter is going to give you more fun factor than a cam. Get a nice efficient one like a Yank 2800-3200 and enjoy that and get the small cam later IMO.


EDIT: if you add all the costs you will find it should also be cheaper (ie better bang for buck)

With a cam you will need: cam, springs, oil pump, timing chain, gaskets, pushrods, etc and a tune

For the converter you need converter, trans cooler, some rubber line, and fluid

My old setup:

02 Z28

MTI X1 230/227 591/571 112
All bolt ons
Stock heads
Vig 3200
3.73 gears

395 RWHP stock heads..So 400 rwhp is doable.

A stall doesnt hurt your mileage that bad. It does affect it a little in city driving, but on the freeway, its locked up just as the stocker would be. Ive run 4000rpm stalls, and I currently have a Yank SS3600 and would NEVER EVER go smaller than that. In fact, Id rather go back to a 4000+ stall again.

I dont think anything will put as big of a smile on your face as a bigger stall will.

AI ported 853's will make more power than stock 243's. If you go this route you can have them spec a cam & springs for almost any desired combo.
