Help Me Choose My New Engine
 
Guys, I have sold my LS 6.0 408 and now I'm ready to upgrade my engine. But, I'm having a little difficulty deciding on which engine to buy. Therefore, I have turned to the brotherhood to help me decide and wiegh my options. My two choices are the LSx 376 long block that GM sells and top it off with a Magnuson TVS 2300 or the MAST LS7 427 or LS7 440.

Mods, sorry I put this in the wrong place. I meant to put it under open discussions. Move it if need be. Thanks!

polls are in! the 376 it is!

I just wanted to say that because I'm the only one that has voted so far. :D

Marcus you know how I voted. Question for you: if you're considering a 376/maggie, why sell the 6.0? No bad choice here, Brother ...:lateral:

Well, I sold the motor earlier this week and didn't consider the Maggie/376 combo until last night. Besides, the 6.0 wasn't set up for forced induction, so I would have had to go back thru it with lower compression pistons, etc. It would have been easier and cheaper to sell the 6.0 and buy the LSx 376.

If you plan to use a TVS 2300, then you have to use L92/LS3 heads. The 6.0 block uses LS2 style head, so it won't work in your application. You could use a different magnacharger that is based on the Gen V blower for a 6.0 Block.

What I don't like about the LSX 376 is the connecting rods is powdered metal, which doesn't tell what is the hp rating for the rod.

Another option to use for a block is an L92 engine, but it uses the same cylinder heads as the LS3 engine. You can buy a complete L92 engine (Engine pullout) with computer and rebuild it to be a supercharged engine. Katech has the oil squirters, and have your machinist install the squirters. You have to buy new custom pistons, forged connecting rods that have hp rating.
Cost of L92 is lower than LSX376. Take the L92/LS3 heads and have them cnc ported. Oh, yeah, I used an L92 block on my engine with the Harrop TVS 2300, but I wanted more cubes. So I used a Crower stroker crank.

Now you have your choice of superchargers, LS9, Harrop TVS2300 or Magnacharger. Depends on how much horsepower and torque you want to make though. Wegner builds the pulley accessory setup for Harrop and Magnacharger. Although, it will take a custom Rick's Tank, custom radiator setup for liquid to air intercooler,etc.
