Willy's Blower Motor:

A machine shop on Oahu, Snyders, in Waipahu, bored my '67 Olds 425 block .030 over, align bored the mains, after machining the main caps and fitting a girdle on the bottom end, and decked the block.

It only took a 12 thousands cut to get the deck perfect.

The main caps had to be milled down to get the girdle to fit right.

This is an Olds motor special girdle made by J&S Machine to beef up the bottom end by tying the mains together and tying them to the block rails. I had to cut and modify the oil pan to fit around the girdle at the block rails.

Here's a link to J&S Machine, in Topeka, IL

This motor has a forged steel crank, forged 7" rods, JE 8:1 pistons, full floating pins, Comp Cams roller setup, it should run pretty strong.....

This should be beefy enough to take a 6-71 on top....

The block rails were drilled and tapped to take a larger stud to hold the girdle solidly to the block.

The pan had to be modified to fit around the girdle at the side rails.

I hope I can get it to seal up without leaking !

Next I gotta power hone to the final fit for the pistons, end grind and fit the rings, balance everything, and bolt it together....

Have had some delays and changes on plans for this motor, it's been sitting for awhile now, but I'll get back on it soon......

PS........

Ya gotta understand that this motor has been in the family for, what, 35 years? Yeah, sumtin like that.... 'Ol Blue', "Beach Cruzah Supreme", a '67 Delta 88, I got it for $50 about 1972, she was our ride to the beach, with kids, grandma, cousins, countless times. So when the rust got so bad I had to finally retire the old gal, I kept the 425 and the turbo 400, complete with a switch pitch "hi-lo" stall converter, all nice stuff.....

Here's some links to more pages on this project:

Tearing down a '67 Olds 400ci Motor for parts....

This '67 Olds 4OO ci motor has been around my shop forever. It has the same 3.975" forged crank as my 425 motor, and the same 7" rods, so I tore it down for spare parts. The block is good too, although it will need a 0.060" bore to clean it up....

Trial fit for the 6-71, a Don Hampton special.
