I debate weather to bring this up but years ago there was a guy named Joe Pitcavish from Natrona Heights Pa.Joe ran modified dirt coupes and other figure8 and circle cars back in the 50s.60s and 70s.A noted driver named Blackie Watt drove for him.
Around the late 80s early 90s I bought out Joe's shop.Among all the race wedge/hemi parts were 2 X-Rams casting dated 1960 the ports were smaller than maxwedge but slightly larger than stock.Joe said they came on some engines he had bought from some boys down south.One engine was a 350 wedge and the other was 361 or 383 wedge,both hi-deck engines.I sold both these manifolds along with a 1964 cast hemi block in the crate to Dave and/or Chip Gerst who were at the time buying cars and parts for Reggie Jackson's collection.Years ago I talked to Arlyn Vanke about those manifolds and he said that he had one in his attic at the shop.

Does anyone have any furthur info on these manifolds?
