It seems like you're already so far in it it would only be a few more bolts to have the block on the bench and have an easy time of it.
I know, I know. I am fighting that thought.
My first real wrenching experience was changing the main bearings in place on a TR-7. My buddy (who had a Rabbit, BTW) said it could be done, despite what the "book" said. He was right, but it took me about 6 weekends (had a crossmember under #2). I told myself, never again. That car had 110K miles on it. I sold it not too long after, but I am sure it would have needed rings fairly soon etc, etc.
On this one, what's keeping me from pulling it are the other 10 cars I own that aren't getting fixed, and the thought of spending serious money right now for pistons, machine shop boring etc that will bring the price of this hundred dollar wonder up to , well, a fair amount. If I can get at least 50K miles out of it, I should be retired and won't have to put the grueling miles on my "fleet", but can just use them all as "pleasure" craft, more or less.
The other problem is that this "small project" is sitting on sand , not on concrete, so it's really going to be more messy and harder to stabilize all that iron on sand.
So far , it is looking like removing the motor mounts will make it work. I was going to change them anyway. I have a new rear mount and I may as well buy a front one...
