Hey Adger, how are you?

Not currently pursuing it, but collected a few LS blocks & LS iron heads for this combo. The blocks will handle a 60mm cam bearing and .937" lifter bushing no problem. The lowest deck height block offered is 9.230", but of course that can fixed. The LS iron heads have the same intake & exhaust ports as the LS6 head, but the chamber is open and rather large at ~71 cc's, so some welding the chamber up and possibly rolling would be needed.

Thanks for the update.
