I'm not sure but I'm guessing it would be a total dog down low with stock lq9 heads.

I thought the original T-REX was one of those barely fit without fly cutting type donkey cams. With flat tops, stock thickness head gaskets, and 2.0" intake valves, IIRC the PTV clearances were in the .036"-.048" range and could pose issues if a shift was missed in an M6 application.
Any sort of 4400 stall or the like would usually allow this cam to pull very hard and due to the low low low cranking compression in a 10 to one motor, they LOVE the bottle.......

There's a local guy running one in an LQ4 and it clears...but it's a dog in the low end.
