So, you've got the 'for now' motor, the long rod 'for later' motor, and the big block 'for really later' motor that you're building motor mounts for? LOL My god - you have the same illness I have.
Yeah and it's contagious too. I'm almost 100% certain I will be offering the big block for sale after I do the mockup and show step by step how I did it. That was my whole point of doing that, because there's SO little on the net about early A body big block swaps. People think it's impossible but it's far from it.
