For the L31, which bolt pattern should I be looking for on the flexplate without having to drill holes? Is it Dual Bolt Pattern like this?

I think the way I typed it earlier reads wrong, he was just suggesting that it be mounted closest to the tank as I can. My tank is in the cab so just like you said on the frame should be where its mounted.

I dont think my HEI is stock, Ill get some pics and post tomorrow.

This is the first Ive heard, hopefully its as easy as your write up reads.

I am really hoping to save where I can but after watching this comparison video I wonder if spending the extra $90 would be worth it for USA quality?

The water pump I have is a long pump, would that require a timing cover change?

A plug sounds cheaper than a sensor to me. Ill have to look around for parts to price on that.
