Unless I read things wrong, TxSpeed has a forged long block LS3 with ported heads for around $8K. All new parts. New block, new ported heads, and your choice of custom cam. Your choice of compression ratio. You don't get a forged crank, but that isn't an issue at Maggie hp levels. If you think a forged crank is necessary, it's available for a few more bucks.

I know I'm a bit of an internet racer, but my TxSpeed long block will show up next week. It's an iron block, but it's also going in a truck. Maggie blown of course
I wouldnt be so quick to discount a crank.I have one of those LSX crate motors and a maggie,3000 miles and the crank broke

Yeah...if your forged crank breaks, it's time to get a FERD PUSTANG, or just buy a horse....the horse will probably run better

That is an option I have been looking at as well. I have been flooding Ted with questions so he is probably about to block my e-mails!!! LOL

That's all I ended up doing. I've pleased with the reliability, drive ability, and performance. I'm sure Ted will take care of you. I think your biggest problem will be the blower. The Maggie Max parts are no longer available which will cap the blowers performance.

If you buy that longblock you can run more boost and still be on pump gas. Look into Padre's car he just went to some heads that lowered his compression.

I have 9:1 compression in my LSX motor, doesn't feel sluggish at all, they have great low end grunt, and they can handle lots of boost because of the compression.

Let me guess, the Internet said they are no good.

Proper built/tuned engines don't break rods or fail
Bearings or pistons.
I was breakin rods and blowing up ls1's when you were still driving rx7's and long before you had a shop so don't come at me like I don't know. Anyone that uses stock rod bolts on this motor with alot of power isn't very smart Anyone that recommends it is even worse. Dyno queens with low rpm's don't break parts properly built or not. Sure the motor will work with a Maggie but so would a motor with just pistons and rods and a stock crank and the stock ls3 heads. I still would want better rods on this motor and there is no way in hell I would test the rod bolts.

Never seen or heard of anyone breaking a stock crank.

So your going to run 1000 Rwhp through a lsxb-15 and not do anything to it? Your going to do this with those rods/ rod bolts?

Why did Ted stop offering the Maggie upgrade kits?

So your just running forged rods and pistons, correct? What RWHP level are you running at. If I remember correctly, its not all that much considering the amazing 1/4 mile times your putting down. Your car has always been my blueprint for what I would like to do with my L99.
