Thanks Don, its not a big rush mate.

Happy new year to you and the boys.

I haven't forgotten about the valve cover gaskets, Steve. Monday everything should be reopened after the holiday break, and I'll get them ordered for you.

Well i was hoping to have the short engine put together over xmas but as usual with any well laid plan something went wrong,

Every thing was going well until the conrods were set free from their box, It wasn't obvious at first until i did the usual checks on dimensions, the rods were 15 thou shorter than the 6.750" they should of been. 15 thou don't sound a lot but would of affected the quench so they had to go.

After a bit of searching i found out that these rods were the hot ticket way back when aftermarket rods wern't available, They are actually Oldsmobile 455 forged rods and to use them would mean having 15 thou taken off the block decks, seeing as the block was finished this wasn't possible so a set of the correct length forged h beam rods have been ordered and will be here next week, I hope


I'm glad i found out before polishing them.








After this little episode i thought i would check that my Cad Parts stage III shaft mounted rocker kit would fit, It did, went straight on and seems a well made bit of kit.

Yep those were the S_ _t back in the day.
We used them in Ford 460 I think they came out to over 500 with those if I remember right. It's been along time ago. we also used them in Dodge 440's and I think the 400's as well. The 400's have more material in the blocks then the 440's did.
I don't remember all the details weather it was shaving the rods or crank and that stuff
I just remember using the rods in alot of other big blocks with a few mods done to them.

not to get picky but i think a would look for better rocker shims then VSI spring shims i would look at stainless steel shims. like T&D JESEL .Crane and others use .McMaster Carr should have some thing better if not use the blue steel spring shims.thats a 030 on there.you can get hard blue steel in some sizes on the rods 015 short is a lot but i know a guy that has a pin boring machine that a EZ fix if you can float the pin

the bbc rods are the hot deal now 6.700 and 6.800 . dodge have a big pin end1.094 and the fork end takes a bigger bearing 2.325? 6.760.long. most all the 460 pistons use the bbc pin end 990 and cranks use the bbc rod bearing 2.200
