Re: 6.0 LQ4 Swap Starting Point?
Ok, for posterity sake I went home and measured my freshly installed lm7's installed dimensions so people cold have some answers of fitment of Dirty Dingo adapters on 73+ engine mounts.
Photo one, DD-2500c dirty dingo conversion mounts used.
I have adapted the 73+ mounts to fit the 69 gmc crossmember as it would fit in a 73+ truck (posted above). I also have the polly mounts placed on the lower setting on the engine stands unlike the placement in the photo above
Photo two, clearance from top of crossmember to the bottom of the truck oil pan I am using, which is 1 5/8" of daylight.
Photo three, view of how far below the crossmember the pan sits, 1 1/4" below the crossmember! (sorry for crappy photo, I really did try)
Looking at these mounts installed it appears to me that the conversion mounts could have been safely engineered or can be modified to moved the engine lower by about 3/4" before any interference would take place between the polly engine stand housing and the plates that mount to the engine. But if this was done the pan would then hang 2" below the crossmember.
