so i want to run a 228/230 cam. i was going to get a intake, like a fast 90/90i was going to port and polish some 243 ls6 heads and have a good valve job done, then longtubes, 2800 stall torq converter, slp intake box, and running a stock ls1 bottom end. what kind of horsepower do you think i can pull? i, is there anything i should know also? thanks for the help i just need some guidence.

 

???? anything

 

might wanna rethink the converter stall. but other than that looks good. should see around 400-430 thru the auto at the wheels.

 

Everything looks good but that converter is waaaaay too small.. Minimum of 3600, otherwise you are wasting your money IMO, even for a car you drive every single day.
You will also need a tune/springs/push rods/timing chain/oil pump....
If you have 2.73s I would upgrade to a set of 3.42s from a six speed.. If you have 3.23s you will be fine.

 

yeah my friend has efi live that i was going to use on it or just have it dyno tuned. The stall i wasnt too sure about so thanks for the help!! other then that i was going to put 3.73 gears and a shift kit. it should be a nice and tight engine then. do you guys think roller rockers would be good also?

 

Skip on roller rockers.. What gears do you have now?

 

i have the 2.73 gears. and are roller rockers just a waste with what im doing?

 

342s will be fine if you are on a budget, if not you can spend a little bit extra and grab some 373s. The track times will be near identical, if not identical. Gears are not important in A4s.

Yes.

 

thanks for the help, i was thinking about going with the 222/224 cam instead, i think i will use a 3500 stall though, thanks for the help on this, ill post more as it gets going. I was also thinking about just getting aftermarket heads, because the money ill put into them i could just get some good after market ones.

 

224 cams are great all around cams... Can be stealthy if you tune the idle high as well.

I wouldn't go any smaller on the converter. And yes, don't waste money on stock heads.. Minimum ge a set of PRC stg 1 Ls6 heads. You can pick them up used for 800$ or so.. That is a solid 35-45Rwhp increase.

 

i like that idle idea and let me ask you this, one some after market heads can i use my rockers from my stock heads? so i dont have to buy new ones? after i do these upgrades i like the idea of a supercharger ))))

 

Yes, you can do that.

Procharger is a nice little Rwhp gain.
If you want to do that though make sure you pay attention to the overlap with the cam you get. You want it to be a boost friendly cam. With whatever heads you get you will want them to knock your compression down a tad bit as well.

 

GM ported heads yes due to the hard ductile iron guides. Most aftermarket heads with bronze guides need rockers if the cam has over .550 lift. Some say .600 lift is the threshold but there was an article in GMHPT a while back that said .550

This is a somewhat controversial topic so I am sure you will hear other opinions.... My stockers were fine on my ported GM castings with .612/.598 lift for 30K miles but I am running YT rockers with my TFS heads on the same cam.....
