Proper engine lifting
Hi guys-
I'm about to remove a 302 from an '88 bronco. I bought some grade 5 bolts from the hardware store. I then put these bolts into the center of the decks where the cylider head bolts would be, two on each side. I have chain connected to these four bolts, then running up to the hook on my engine hosit.
Is this safe to do? I'm worred that I'm going to snap the bolts.
thanks.

There's no way you will snap grade 5 bolts just by pulling the engine. If memory serves me correctly, the 302 bolts are 7/16".
They have way more shear strength than you can break. They'll strip out of the threads before they'll snap.
I just pulled my 351W out using one head bolt on the right side since there was no lifting bracket. There was a bracket on the left side, and it was bolted to two wimpy little 3/8" bolts at the factory. They were rusted bad (exhaust heat) but held up just fine.
The chain for my cherry picker is held in the boom by one 3/8" grade 8 bolt. My girlfriend was even amazed that that one little bolt could hold all that weight.

My preference is to pull an engine with the heads on and using bolts in the back and front of the heads in order to eliminate any chance of scarring the deck surface with the chains. Lots of people use a bolt in the back of the passenger head and one in the front of the driver's head. When positioning is important, I prefer to use a length of chain secured to the both heads at the back and another secured to both heads at the front, then connect the chains to a load leveller. This way, the engine doesn't twist when you tilt it with the load leveller.
Anyway, glad to hear your project went fine.
