Motor Rebuild Questions - Sleeve Type, Heads, Cam ??? Well as most of you Texan's know that I cracked a sleeve in my motor.. I have a few options.. Im putting a 6-spd back in the car, first off. Next I'd like to break the 550-600rwhp area N/A.
I have a few options.... ...and questions....
1.) I can get the two sleeves that are problems fixed, they are the last generation of dry sleeves MTI did. I could also get a Wet Sleeve.. For reliability, etc... I know the Wet will be better, but how much better.
2.) What kind of cam should I go with. I am already a solid roller car, 260/266 @ .675" of lift, etc.. Jesel J2k Rockers, and all the goodies. Im looking for something REALLY aggressive if I change.
3.) My heads are MTI Stage 3 LS6s, I may have them cleaned up a little and see what else is left in them, but Im not sure.
4.) What kind of intake should I go with? The LSX90mm looks promising, but not sure how promising.
5.) The people making high HP #s, how many are doing this with just LS1 Edit, not like a FAST or a Big Boys unit?? Also how much is the Big Boys unit and when will it be available?
Sorry for the "list" of questions but Im going to start getting my motor rebuilt and I want to make some KILLER HP.

I'm not convinced yet that the MID sleeve setup is proven. I check this and other boards very frequently yet hear almost nothing about the results of these block. The dry sleeve is proven and many many people have good results with them holding up well under high power and even big power adders.
My new block is once again a dry sleeve design, with a smaller bore. I sold my 3 year old 4.060 bore block and the guy punched it out to a 4.100 bore 422 with Nitrous. The old block is still holding up well.

2. That should be enough cam to achieve your goal, we have 427's making 540 RHWP with hyd roller cams
3. I would love to flow them, our newest design flows 340-350 cfm on a 4.00-4.125 bore
4. We have installed 2 LSX 90mm setups on 408 cu in engines and on our dyno back to back was 20 RWHP over a LS6/ ported stock TB
5. LS1 edit should be fine for you to achieve your goals
What size engine do you have and do you want to run pump gas? I have had other types of small blocks on my dyno make 700 RWHP on motor, so I think your goals are resonable.

Now, I don't want to hi-jack your thread, I just have a couple of questions for you. How driveable is your motor? Would a solid roller set-up in a '98 trans am with a 6-speed and 4.10's be a PITA to drive everyday? Also-what is the advantage of going solid roller? Looking at my options here, and wanted to ask someone who had it on their car.
Thanks,
Jason

Solid-rollers cars that are setup properly produce more torque and horsepower throughout the entire RPM band when compared to a similarly setup hydraulic-roller setup. It also allows for motors to be revved higher, which can be beneficial. As far as your setup goes, the gearing you choose depends on how far you plan to rev the motor, and where you want to make power.

I believe the Wet sleeves are worlds better...you already have problems with the dry sleeves. We have been doing quite a few Darton blocks lately. You goals are reasonable even with the cam you have. We also tested our intake on a 427 solid roller car and it made 43rwhp with a 78mm TB and lost nothing down low it will scream with a 90mm on that motor.
Thanks Nate
