motor mount adaptor template

[DBRODS]

The mounts that I designed move the motor back 1'' and up 1/2''. Here are a few pics, only downfall on my design is you have to redrill a hole on the SBC pocket, and if you have a few tools no big deal. It places the motor back in the engine compartment way better than the standard mounts. In the upper pic the one on the left is the standard mount.

your's are very similar in configuration to the Hooker mounts.

I haven's seen the hooker mounts, got some pics or linkys....

I think you went a little further back than I did, I drilled a different hole in the mount bracket to pick up the lower forward boss in the 5.3L block, which I think is what you did as well. If I didn't want to reuse my driveshaft without modifying it, I would have gone further rearward, there is about 1.25" room easy to go back, and it makes fitting truck exhaust manifolds and a stock 99-07 y-pipe past the frame easier (frame gets wider as you go rearward).

I didn't raise my engine any specifically because I wanted to reuse the mechanical fan too (my truck is set to tow), and my engine position puts the fan smack dab in the middle of a 88-95 V8 fan shroud. I used the 95 V8 radiator too.

If I was to do it again, and I just might this summer, I'd move the engine mounts on the crossmember rearward at least an inch, maybe further. If you make adapters like noted here, mine or DBRODS, it is very unlikely you'll get the AC to fit in the lower right position. The mount bracket needs to move rearward. IF AC is not a concern for you, disregard these comments.
