I bought a short-block, and I don't have any bolts that fit the bell-housing side of the engine to base sizing off of. Everything I have is standard...figures.

Does anyone happen to know the size/thread pitch of the threads? There are 2 big bolt holes at the top, and the rest appear to be the same, smaller size.

I did some research, but all I found were smart ass answers about people not having any business around an engine. I have my running engine/trans in the car, and no metric hardware laying around...

Any help is appreciated. maybe zzp/ottp/powell/etc. can chime in?

 

m12x1.75


the 2 larger ones are m16x1.5

 

Thank you, sir

 

Did these bolts work for you?
