The sbc rods are .943, the Y .871, so I had to take off .042.  The chev big ends are offset, so I took all the material off the "wide" side of the rod.  I made a fixture so I could cut a chamfer on the bearings to clear the radius on the crank.  The crank guy said they make a chev bearing that is narrower, just for that purpose.  I used the standard bearings and chamfered them.  I would go with the Wiseco if I were you.  Cost isn't that much more, and you will have a thicker piston top, I'm sure you are going to use more boost than I do.

On using SBC type rods, when you narrow the big ends, what is the difference in sizes, and is it enough to foul up rod bearings?  Or can standard, non-modified bearings be used?  I am still calculating and working long rod combos in my research.  I saw those 331 Ford (mod motor) rods that are something like 6.6 or so, but that's just a little much, unless you do custom pistons.  I got a form from Wiseco today, and for $800 or so, I can have a set custom built to my specs (ring lands lowered, thick crown for gobs o` boost, etc).  Before I can do any of that though, I have to find a good rod though.....

I used 6.300 long Eagle rods for large journal sbc.  Had the pistons honed out for the chev pins.  Narrowed the big ends of the rods to Y size.  Had the crank ground to chev size at stock Y stroke.  Decked the block just enough to get it square and equal on both banks.  Pre-assembled the short block without rings, and used a dial indicator on the flat portion of the pistons to find that they came out of the block .034.  So I machined off the dome plus another .034 to get 0 deck.  There are two very small eyebrows left of the original valve clearance notches.  Glad I didn't have the crank stroked, the pistons may have been too thin on top with 6.300 rods.

I love the smell of burning rubber in the morning!

Yes I did. Thanks for the information. It will be a while before I can seriously consider it though. Glad to hear the Hurricane is ready to go again. Can't wait to see it run! Always a pleasure. Chuck in NH

Y's guys rule!
Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

Thanks for the kind words.  Ted, I don't expect much change in the power, since all the breathing parts are the same, only have lighter pistons and rods.

Chuck, did you get an email from me a week or so ago?  Concerning the build of this engine.
