LS1 swap - need block thread sizes
Ok,
I just bought an ls1, which hasnt been delivered yet. as i want to get in on my engine stand when it arrives, i need to get the correct bolts to mount the engine on my stand. I will be using the bellhousing bolts i guess (where the t56 it comes with mates to)...
What size (mm?) and thread (pitch?) bolts do i need to mount the ls1 on an engine stand?
Cheers!

M10 - 1.5 is the thread size. You want the bolts to thread into the holes AT LEAST 10mm. Preferably 1.5x the bolt diameter... In other words, dont just catch the threads into the holes and call it good.

Re: LS1 swap - need block thread sizes
That works too. I had a hard time finding M10-1.5 threaded rod locally though. So I went with long bolts and washers to make up any slack.
