How are the street manners on your set up with the A4? I hear it's all in the tune...speaking of which, I wonder why your numbers aren't at least 30 higher than what they are.
well the car is crazy loud and thats with the borla stingers.

street manners are good but its far from stock. and yes it is all about the tune. mustang dyno and with a a4. i dont think i would want it any faster:o

Nice lamp, a little expensive though at $500. So the Cadillac race lifters are top notch and a "must have" item? I really have been considering it. There was a secondary list of parts that I had in mind that I was only going to purchase if members specifically called them out on this post. Lifters was one of them. Can you show me a picture of where they sit in the valvetrain? Seeing their location is usually a selling point.

I think I'm going to give my heads and valvetrain components to my installer a few days in advance so he can build them and set good wipe patterns on the workbench and to ensure I have proper pushrod height (thanks Vettenuts)

So you think my A4 with ss3200 stall and DTE 3.73's will run like a maniac at about 480RWHP? I am trying to build a remarkably fast street car that is also a dyno queen for bragging purpose.

Got any sound clips or videos you would like to share? Just a little teaser before mine gets set up.

From the stock exhaust to my current set up; adding:

Borla Stingers - Car found its *****
LG Pro LTs - NIGHT AND DAY (turned into a monster!)
3.73s - Changed the exhaust note to a higher pitch


I actually got pulled over by a cop that owned a C5 because he wanted to know what kind of exhaust I had. Sweet parts get you out of tickets apparently...does that mean next month I'll be immune?

Here is a pic from when I did my heads. I put in the Caddy racing lifters and I love them. They are a lot quieter than the stock lifter and they can handle higher rpms.



The lifters go in the 8 holes above the 4 pistons. They are held in place by a plastic tray that holds 2 lifters per cylinder (intake and exhaust).

From what you've bought, I suspect you'll need non-stock push rod lengths to keep your valve train geometry correct.

Here is another picture where you can see the lifters in the trays installed in the block.



Depending on your compression ratio, I recommend you ditch the ARP head bolts and go with studs. I didn't do studs the first time I had my heads off and regretted it so I did studs the 2nd time I had the heads off. Sell your new ARP bolts on the forum and get a set of 12 point studs.

I should be at a tick over 11:1 with compression. ARP is what LG Motorsports sold to me for this kit including push rods. Think it's possible that they may have sold incorrect parts for the build?

I have a better idea now of what lifters do. If I'm thinking straight here; they should be the part that is in DIRECT contact with the camshaft. In turn, the camshaft pushes the lifter which then moves the push rods which then move the rockers which will open the valves.

***Learning has ocurred***


Tune? Will my car operate with its current tune or will I have to have it towed to a tuner once it's built?

You will need to towed because it wont run long with the 30# injectors with the stock fuel tables.

Its gonna be a sick setup. Very similar to mine that I am doing excpet I had Tony Mamo port my 205's and FAST 90 and mine is a MN6 with a 150 shot Good luck and Im looking forward to the build

I was really considering a 100-150 shot of nitrous for some added fun. Why not? I've got stronger components now. What are your experiences with the juice?

I may need to put some tubbing in the car for extra meat in the rear...it already spins the 295s like bicycle tires

What difference do you get from porting your 205s? I figured they were already as good as they come out of the box.

Getting a set of Cadillac CTS-VR hydrallic roller lifters from LPE.

Are these complete as is or is there something else crazy I need to buy.

I'm heading out to my shed right now to look for a shovel....there's buried treasure out there somewhere to fund my project!

I went with pretty much the same setup - AFR 205's milled to 59cc, ported Fast 90 and ported LS2 TB, underdruve pulley, G5X3 on 112 lsa, 30lb svo's, 921 springs, comp r lifters, comp pushrods, cometic .040's, etc.

I had to flycut the pistons. I also went with stock rockers based on the suggestions of LG. I was torn on this as Tony Mamo suggests using the YT's. The YT's will use a different length pushrod than what the stock rockers use. I've got a brand new set of the YT's if you're interested. Also, be careful about the cometics sealing. Mine didn't and I had to pull everything apart a second time to coat them with copper gasket sprary in order to get them sealed.

Too bad I didn't talk to you a few days sooner before I bought a set of YT's. I've heard many stories of the Cometics not getting a proper seal. I'll be a bit irritated if my rods don't fit now. That will put me in some more down time. I knew a guy that had the wrong size rods in his Procharged set up and that sucker was loud (valve train noise). I'm trying my best to get it right the first time.

My only wish is that I don't have to machine any surfaces to get this all to fit. I really hope that I can put this together as is.

See my sig - you WILL have my setup, almost EXACTLY! - I put in Caddy racing lifters - I wouldn't worry about different rockers - use the stock rockers

I've got a Melling Oil pump for sale if you are interested. Let me know.

How does the car feel with all the mods? Yours is very similar to what I've got. I already purchased all of my parts. All the parts that I listed are sitting in my garage waiting for a new home (inside my LS1). What is the difference between Yella Terra rockers and stock? Why would AFR suggest one and LG suggest the other?

I'm thinking maybe someone wants to sell rockers?

BE SURE!!!!!!!!!! to put the BLUE spring in your oil pump BEFORE you install it - the Melling Pump comes w/ a RED spring installed - you want to put the BLUE spring in instead!!! otherwise, you'll end up w/ 90+++ PSI oil pressure

I spoke with one of North Carolina's top tuners today about the YT's. He doesn't think they will work with the H/C combo I've got. He will attempt to use them though. He also mentioned that I should use a stock GM head gasket vs. Cometics. He said that Cometics should be used for race applications and not DD's like we all have. He told me the process that he goes through to keep them from leaking but says 100% of customers will be back within a year and a half with a gasket leak. It's believable from all the threads i've seen on them. He believes in the quality of LS1 stock rockers. This guy has tuned 100's of LS1's (his specialty) and he sounds very intelligent when discussing the mechanics of the build. He sounds interested in the customer; not your wallet. Good pricing estimate as well. I think I'm going to send the car in next week for the build.

Thanks for the advice on the oil pump. You're not the first to warn me. My pressure already saw an increase with the higher gear ratio in the rear end. Don't need anymore smoke screens shooting out the tailpipes.

If I put the rockers up for sale; you're interested?

My only recommendation, re-read Tony's posts, YT's will work fine on those heads as long as someone is willing to take the time to set them up. The stock rockers wipe with a wide pattern. They are hard to shim and will also require shimming. The AFR heads have bronze guides, improper wipe and you will be in for valve guides.

The tuner said he set up a set of YTs on AFR before and they hit the heads hard (no clearance). They weren't the ultralights though; he is currently working on a set of those for someone and will let me know the turnout.
