You should know at mi casa I have a 56 3/4 ton, a 98 K1500, an 05 3/4 ton, a 95 vette, all GM, and a GM 350 engine in my 53 Willys and they're all holding up fine.
86 Astro, 97 Safari, 97 Suburban, 98 Tahoe, 99 Suburban, 2000 Express 1-ton, and a 327 in my FJ-40.
Right now one Suburban is down over axle bearings, the FJ-40 is in need of some restoration, and there's a 75 G-10 that could use going through. The rest are on the pavement.
Oh, and there is the 87 Dodge D 150 with a slant 6 I use for a utility pickup.
