Ok so i ordered these, what else do I need, I've been searching around but I'm getting mixed solutions, can someone help its for an 1989 obs thabks guys
Ok I think I know what I need but I need confirmation, the motor plates and pads plus the stock silverado frame mounts?
dirty dingo mounts
Whichever you use, whether Dirty Dingo or engine plates, they need to be the 1" set back type for the Old Body Style truck(OBS). I ordered standard plates for my '93 and it placed the engine 1" forward of where it should have been. That's why I'm inclined to say that you need the 1" setback plates so you don't have any driveshaft/crossmember issues.
I used plates so I could use the original "clamshell" mounts from original 5.7 engine. Some plates have fitment issues that need to be addressed. Since I ordered the wrong ones, I didn't have any fitment issues. The 1" setback plates may cause fitment issues but are easily remedied with a 4" high speed grinder.
I used the trans dapt 1" setback plates and the only thing that needed to be done was grind them in certain areas for clearance. When you get them and try to fit them to the block you will see what I mean. You used the original truck clamshells but cut out the middle section because it doesnt sit flat with it there and also I had to cut down the bolts that mount the clamshell to the plate or it would bottom out before it tightened and you dont have to used the nuts that it comes with. I put them on and dropped the engine in like it was meant to be there no prybar to make it fit nothin the long bolts slid right in
Cool guys thanksndor the info I think I already have it sorted out
Could I use the 1" set backs on my v6 mounts ? Or do I have to change it either way.

I make mount brackets that are not adapters, but are bolt on pieces. All of the adapters that have you bolt the SBC clamshell to an adapter plate make the cross bolt holes not line up with the mounts on the frame.
The brackets are made from 1/4" steel, and are made to put the back of the engine in the same location as the old SBC that came out. This lets you use your existing trans, and if you are building a 4WD truck, you don't have to mess with the driveline AT ALL. Stock and aftermarket manifolds/headers fit. I have even run a complete 99-07 Exhaust, from the heads to the tailpipe with minimal modification.
Works on 88-98 2WD and 4WD trucks. If you are upgrading from a V6, you need to install the mount cushions in the V8 location, there are holes in the frame already to do that.
I have personally run these on a 93 Sierra 2WD and 94 Z71 Silverado as daily drivers. One set has been in use for 4 years on a daily driver. The 94 Z71 has towed 9000# on these mounts, been off roading, and similar versions of these mounts have run 11's (4100#) in the 1/4 mile.
I sell these for $93/set shipped, including 8 M10 fasteners to attach them to the block.
PM me if interested.
