In a couple of weekends I'm going to take the engine & trans out of my car to start working on them. Does anyone know what bolt sizes I need to mount a 302 to an engine stand?

This is probably a newb question, but I have searched and couldn't find an answer. I just want to be prepared as I can be when I pull it out.

Thanks,
k

 

I'm gonig on memory here but I think the head size on the bellhousing bolts are 5/8 which should mean the bolt size is 7/16 course. The length will depend on your engine stand. You will need to meassure for that.

 

67 Pony is right, 7/16" course thread, which usually is a 5/8 wrench to fit.

You will need these to thread into the block between about a 1/4" to 1/2".

Any grade 7/16" bolt will be just fine to support a SBF, but for my comfort, I like a minimum of grade 5.

 

I agree on grade 5 at least. That said I got grade 8 bolts since the total was only a buck more.

 

JMD :-) welcome back !!!!!

is that a given that 5/8 socket bolts are 7/16 thread? i mean is that always 1/16th apart? i mean normally (not using mini socket ARP bolts). i never knew. new to this imperial stuff

These are the standard hex sizes for US bolts

1/4" thread - 7/16" wrench
5/16" thread - 1/2" wrench
3/8" thread - 9/16" wrench
7/16" thread - 5/8" wrench
1/2" thread - 3/4" wrench
9/16 thread - 7/8" wrench
5/8" thread - 15/16" wrench
3/4" thread - 1-1/8" wrench

I'll save it away and let my buddys know
