engine on the stand
Looking back at your stand closely, I see it is the absolute weakest type made. The tubes that the bolts run through are welded to the tips of the fingers from the head. Look at how that's made. Think of how much pull force is being exerted on those welds. I have had one break one weld on one tube, then another.......all the while I was rushing over to get my engine hoist. I barely made it and got the load off before the third weld broke. Get that engine on the floor. Now.
Then go get a better engine stand. Here is what my Hemi has been on for well over a year.
