Anybody know anybody who has an MRL perf 318

Over at E body mopar forum, I guy put up some impressive 340 hp to the tune of about 474 hp and about 450 ftlbs, all built from MRL with no stroking.

Not bad.
Anybody ever see/hear similar from a 318 from MRL?
How about their roller lifters? Any experiences there? Price seems right.

Thanks
