Just wonderin'...

If the Graveyard guys are doing it because that's how the factory did it....that's Poser 101 right there. There are a billion things they are doing that don't echo the factory, so why is that one of importance? I really think they are doing it for the reason I mentioned. Few of us are working on 100% type restorations.

Greg, I don't think GYC, or anyone else is installing as an assembly from underneath to be a "poser"...poser for what? It looks like a much easier way to roll than fighting tooth and nail and scratching up a freshly painted engine bay/firewall/tunnel area with a freshly painted engine. Like I mentioned, this ain't my first rodeo. I'm looking for a better way than I had to work with back when bell bottoms were in style (first time around). As for a tranny jack, yeah...it would be great, but why dump $3-400.00 into something I'll hopefully never use again in my lifetime? If you're planning on doing numerous restos, then it's a great idea! I'm not. I'm looking for the fastest, easiest and cheapest way to install the engine and K-frame with the least collateral damage.
I did my entire underside on my back with a wire wheel and a can of brush-on Rustoleum. Would it have been 1,000 times easier to do it using a Whirly Jig? You bet! But it's a one time deal, and I can better use the $1000.00+ in other areas. Would using a Whirly Jig make a guy a poser as well? Sure hope not, because if I had one I would have used it.
I say whatever works for you and your budget, go for it. But that's just me.
