Here's a "link" (https://www.fordbarn.com/forum/showt...le#post1878599) to some reading about a build we did some years ago!

I still have the "pattern" here with me. The final installation was done without the necessity of align-boring OR even align-honing the mains!

It tied the center of the block together and worked really well! The stock car in the picture ran every weekend for some years and ran upwards of 5000 RPM. Never one single issue, it was built for a very good friend of mine!

Thanks, Gary in N.Y.

P.S. One more item I would certainly look into would be to get the block "extrude-honed", never tried it but I believe it MAY be very useful for chasing HP numbers?? Here's a shot (again) of the "pattern" for the girdle.
