Haha I need a wheelie bar now! I'll keep you guys updatedThat's one heck of a wheel stand !!! Man you got some serious air !!! Lol. But yes I to have heard of and experienced cinder block fail . Please be very careful . Heck if was closer I'd build ya a set of angled blocks to use keep us updated on how things go '
I made some 2'6 - 4' Stands about 15 Yrs ago for my brothers 69 Mach 1 but they wouldn't fit under the car with the engine crane in the way.That's not cement blocks you've got under the front of the car, is it? Cement blocks breaking have injured many people who have used them as jack stands.
I recommend following the advice of the michigan speed article on removing engine from bottom. Build platforms out of 2 by 4's like he does. Much safer. If you don't have the article, pm me with your e-mail address and I'll send it to you.
It does yes, but it really was simple. I think lowering the body back on the motor might be a pain when its all doneWow seems like a lot of trouble pulling the motor from the bottom. I pulled mine from the top. It will be worth the trouble when you're done. Good luck.
