Thank you carl , I really appreciate that.

Steve  I shipped the bolt out today by usps,should get to you early next week.  Carl

Sorry about the mistake,the bolts I have are 2 7/8 " long,and yes I do know how bolts are measured just had a senior moment    Carl 

You don't include the head when measuring bolts, you always measure from UNDER the head.

Bolt lengths are typically measured as ‘under the head length’.

Steve. not sure how you measured your bolt but the ones I have are 3 1/4 " long that is total length including the head.  Carl

I got my block back from the machine shop and I measured one of the main cap bolts. It measures 2 and 15/16. My address is, Steve Takacs 25 holly cir. Midway, GA. 31320.

I will measure one when I get them back from the machine shop

Knowing what year block you have could help but a quick measurement on your end would simplify this.  I have an assortment of those main cap bolts in a box but do need to know the length you need so you can be helped.  As stated earlier, the main cap bolt lengths were not a consistent length during the years of manufacture for the Y engines.

I would be a lot easier if you just measure the ones you have so I can just ship you one,no charge   Carl
