Plastic Mockup Blocks
Who has used one of the LSX plastic mockup blocks/heads and how did you like it? Was it light enough to move around by hand? Useful?
I am thinking about getting one to help with my swap. I have firewall mounted A/C and I'm thinking the mockup block & heads would help a lot to figure out where I may need to modify things. I don't want to stab & restab the motor a bunch of times if I can avoid it. Any opinions on their usefulness?
Also when using a mockup block, is it important to bolt up the tranny to determine final engine location or are just the motor mounts adequate? It's been a while since I've pulled or stabbed my engine and I can't remember if it moves around a lot when you mate the tranny or if the motor mounts by themselves determine how the engine is angled.
Thanks for any help/advice.

Pulling the engine in and out a couple dozen times is a rite of passage in building your own monster car. Consider it a character building exercise.
Plus it is usually the accessories (like exhaust, alternator, AC etc) that forces the engine to be shifted in one direction or another. I don’t think a plastic block is going to be that detailed.
At some point you are going to want the full engine and trans in place before you set the final motor & trans mounting points. Being able to adjust all three can be crucial in getting the rear diff pinion angles right.

Cool to have - yes, necessary - hardly. Depending how well you measure and what your level of experience is you won't have to do it many times.
Since we are talking about expensive one-trick-pony dream tools - does anyone have a set of header legos?

I used a P-Ayr foam block for my project mock up with great results. I held tight tolerances around the oil pan and headers and everything was spot on when it came time for final assembly.
