These 402s are a god-send for sure. Everyone can afford a stroker motor now. But things are about to get even better. GM will be releasing their 6.2L L92 engine soon for production truck/SUV line. This block will basically be identical to the LS2 except it will have 4.065 bores rather than 4.00. Therefore, building a 427 will cost the same as the current prices on the 402s. Nice.


posted in another forum. sounds tempting

 

4.065" bore X 3.622" stroke = 376 cubic inches
4.065" bore X 4" stroke = 415 cubic inches
4.065" bore X 4.1" stroke = 426 cubic inches
4.065" bore X 4.125" stroke = 428 cubic inches

...nice...

Although the L92 heads have similar ports as compared to the LS7 the heads the L92's will not line up with the LS7 intake manifold at least from the comparison pics I've seen posted here... prolly be a sore subject until Wilson or somebody steps up with an aftermarket composite piece. Or maybe GM will shoehorn the L92, or a derivative of it, into a GTO, SSR, or Trailblazer at some point with a low profile intake...

Bill

 

No dice...

Trailblazer/SSR has the tall truck intake.

 

Well, here's hoping GM does something with the L92 heads other than stick them in trucks... other wise it will be up to the aftermarket to come up with something.

 

Agreed.

All to often these days, the trucks get all the cool stuff.

 

But a Fast 90 will bolt up to the L92 heads ...correct??

 

Not even close... like I said hopefully Wilson (who I believe manufactures the intakes for FAST) will come up with something. Heck with today's modeling technology they may already have something in the works... just speculation on my part. Corrct me if I'm wrong but I think Wilson/FAST had their 90mm intake out with the 90mm GM TB bolt pattern... long before GM C6/LS2 parts were available to the public. So, hopefully they are on top of it...
