I have seen LS7 427's, and 1 LSX 427 build, but I have yet to see an L92 build. If you have done an L92 build how did it go/perform.

My buddy is putting a ls7 crank and rods in a ls3 6.2l block and making a 414ci or something like that and keeping it a wet system with ported l92 heads. He is going to buy a ETP carb intake with a 950 prosystems carb.

When we took all his parts to Billy Briggs from W2W we got to check out his new shop and man was it nice and clean and huge. He bought most or all of the machines from W2W. He also has a engine dyno up and running.
He mentioned that Carry from ETP is moving in with him.

LOL. I hope so. You are starting one for me now

I have lost a lot of hope concerning my previous builders desire to make things right (desintegrated, built 347). He has stopped responding to anything I send him now.

We typically stock the l92/ls3 427s for customers looking for a extra stroke setup. They seem to be pretty nice little short-blocks for the money! We're building one to combine with the new PRC 237cc head!! Should make over 650flywheel horsepower....

Brian actually has some re-worked by Tony Mamo AFR's he's going with but TSP could make things very interesting with a lower priced efficient aftermarket casting.

Hey Chris don't give away all of my secrets.

I am glad to hear there are others out there. There still aren't very many though. The decisions for it have pretty much been made, but that leaves me with the biggest problem right now....tuning. I am stuck in Germany so I am learning as much as I can. Its just me and EFILive.

With the few numbers I have seen in this post, I sure hope I can exceed 480 to the wheels. genmex and 2c5s, How do you feel about the numbers your engine has made?

My previous itty bitty 347 put down 470 n/a. Unfortunately, it lasted only 2000 miles when it busted a rod bolt and disintegrated back in July. The builder isn't communicating very well with me. So, I had to dump even more money into another build. This one has to be the last. So, I want it done right.
