Hello all I am looking for bolt pattern dimensions for the 5.3.

I only need the Block/Bellhousing dimensions. Based on crank the center line.

i dont know that anyone will be able to help on mesurements, but standard sbc stuff will bolt up, if that what u are looking for. one bolt hole doesnt line up, but it works. fly wheel hasto be spaced out though.hope this helps

yep, GM redesigned the transmissions in a different year than the engines so all the bolts line up exactly the same (except one) on an older V8 or an LS

Yes, I am aware that the LS style Bell bolts up to the early SBC I appreciate the responses. I actually am not bolting the trans up to a SBC or LS. I would like the dimensions so that I can make an adapter plate to another project I am working on.
