Forged short block

[Gelf VXR]

For those going forged bottom end or short block, what is your route and source for parts?

Ive spoke to Roger about engine out and a 416 stroker rebuild, cost is very prohibitive, much more than below, ill consider to do the grunt work myself. Build rest of the engine first, pull swap out the LS2 and sell that to help finance the project.

My goals are NA daily driver with a lot of grunt, Ive got Mast 240cc heads with 2.165 valves (not 2.08), max rpm 6400, I don't want a dry sump, Ill get custom cam from FTI.

I'm thinking about importing a short block, either a LS7 or a dry sleeved 427ci LS3 (overkill?) The ERL is solid and leaves room on the table

Mast mahle/compstar LS7 427 = 7500 USD

Texas speed mahle/compstar LS7 427 = 7350 USD

cnc motorsports mahle/eagle LS7 427 = 6100 USD

ERL dry sleeve weisco/compstar LS3 416/427 = 7900 USD

Any thoughts?

Thank you for your input, I'm steering away from a stroked LS2/3 without sleeves, choice is sleeved LS3 or LS7 block, with 4" crank. ERL can be bored from 4 to 4.185.

I've no plans for power adders, but who knows, I tending towards ERL, choosing an ls3 core, the ls3 came after the LS7 and is said to be 20~30% srtronger and has improved breathing bay to bay.

The lsa / ls9 again stronger than the ls3, also has oil squirters for additional 825USD, how beneficial are those oil squirters on a street NA application?

That's my conclusion for the way to go forward also
