Best block for forced induction ?
Best block for forced induction ? Looking to start a turbo build not sure which block to go with lsx ,erl. Or maybe the 6.0 block not sure of the up rating on it compared to other two blocks. Would rather have over kill as to running on the edge. Planning on a 408-427 ci motor with a 88-91mm turbo. Any info or opinions would be greatly appreciated
Thanks
Thanks

a lot of guys running stock 6.0 blocks. they can handle 1000-1100 hp just fine. i was in the same boat looking for the best block to start with and i think i will end up with a 6.0. the lsx is nice but expensive . 8k for a good lsx short block with all the trimmings but it can handle 2000hp. i dont need that

For my project on my Trans Am I will be doing a 427ci stroker (6.0) with a 88mm Precision Turbo with a forged crankshaft, pistons and all other good stuff. I should be anywhere between 900-930HP at the flywheel. At the HP range you are looking for a LQ4will do the job but consider investing in great parts. Forged rotating assembly and bottom end, such as a Callies Dragonslayer forged cranshaft, forged low compression pistons with the right compression ratio for your HP goals 
Just get your self with a great engine builder and he should give you an idea of what to start looking towards investing on. I would recommend an late model standard deck LSX block, but that also of course has to do with your budget.

I dont care for the stock blocks with a stroke longer than stock because of the short skirts in the blocks. I have had very good luck with the ERL engines. I use a long block that they put together and it has ran well.

Any four bolt block will do that. ERL 6 bolt superdeck or LSX block, nothing else. Otherwise you will be spending more money down the road.
