Team 42 AMS Racing – Kittler
Raymond Kittler and the AMS Racing team were competing in the Xtreme division with an LS engine displacing 428 CID, and featuring All Pro cylinder heads. This combination was definitely making serious power while going through the required warm-up pull. The team decided that power could be increased by fine-tuning the carb calibration and went to work changing jets at both ends. In making the scored qualifying pulls, the engine produced a best of 839 peak horsepower, ending the session with a score of 2933.2, which was short of that needed to qualify for final eliminations.

*LS 7 hydraulic roller spring pressure
I have factory ls7 heads with del west titanium intake valves 73grams, ferrea super alloy ex valves 99 grams. Cam is 264-271 .684*.684, the springs are 200lbs on seat with 525 open. Stock rockers with trunion upgrade. Its going in my weekend jet boat. Im concerned about breaking rockers and bolt. Engine is a 444, 14:1 on e-85. What do you think? Drill head for 3/8?? Really didnt want heavy shaft rockers but will buy if im going to break ****. Thanks

*Solid roller ls7 with factory rockers
I've got a .650 lift hydraulic roller in a class n.a. ls7. This engine was not built for this class. I took it out of my jet boat this winter and put it in my buddy's car. 3,000lbs 9" tire 4150 carb. We went 9:15 with many issues. I think it'll go 0's to maybe a high 8 but need more. I had lsm make me a can for the springs I have now. Like 180-440 IIRC. We are hitting limiter 200' before the stripe at 8,400. It needs a gear change. But do you guys think I'll have issues with the stock rockers and a small solid roller? Its ,670after lash. It'll all be done with push rod length. These are stock heads not aftermarket. Thanks.

Well I dynoed 2 weeks ago after running 9:15 @146mph @3,050lbs. It was hitting the limiter about 200' before the stripe. I turned it up from 8,400-8,600 then we had a dead battery and couldn't make first round. It sucks cause we were #2 qualifier.

So out came the hydraulic roller and in the solid. Still with stock rockers. It made 824 at 7,500-7,700. The solid I made 870@8,000. I made the dyno pulls the same from 5500-8,000. The average was up 30hp but 8,000 was up 65hp. Running car today hoping for 8:90's.
The hydraulic was 264/271 .650 lift 113 LSA installed on a 111. Now it was perfect for what designed for my jet boat. It made over 600 ft lbs for 3,000 rpm with a peak of 680.
The solid is 270/284 113 LSA on a 111 W/.670 after lash. Which is more in line with what we need for the car.
I have all pro heads coming from WCCH in a few weeks. It'll get shaft mounts, a cast tunnel ram a different camshaft. So that's not just for the august race but also going to be the way it will be run for drag week. I will dyno again next month. I will also run something besides my 4150 that we're required to run for the local class. Drag week can run whatever....
The heads are factory g.m. cnc'ed. I had my friend do a valve job on the newen and some short side work that's it. I'm pretty happy with the heads. They work great for the boat but now that we got it in a car for this local class and drag week they're not enough.
I will buy another cam with more lift for that package just really not sure what I should do cause its going on drag week. I'm thinking right around .800lift possibly a bit less. We have to run 1,200 miles plus a bit of street/testing before we go. I'm going to order jesels Monday. I really like T@D though too.
