I started on the aluminum block today. It is new, but I'm afraid it's been violated a little. It's been decked (this is bad news since rarely does anyone do this right) You can see the sleeve perfectly flush with the aluminum.


Here's the problem. We put cooper rings on top of the sleeve flanges, and then installed a torque plate and torqued it to 130 ft/lbs. This is done to make sure the sleeves are seated tight in the block. As you can see in this picture, they were not. they are now .012" below the deck. Now we have to deck the block at least .013" and start over. The torque plate seating of the sleeves has to be done BEFORE the block is decked.
Almost every aluminum block comes with the sleeves sticking out of the deck a little. They will almost always move down .005-.015 when torqued into place. When the sleeves are installed, the block is heated to about 200 degrees. then the sleeves are hand placed into the block. when they are placed into the block, they are seated in pretty tight. when the aluminum cools, it shrinks at twice the rate of the sleeve, leaving the sleeve sticking out of the deck.
At this point, if a person decks the block, the sleeves will have clearance under the flange at the top. The first time it is touqued, it sinks.

Additional Weight

Based on your your previous assessment, what would you estimate the same engine to be with a Weiand 1993 cast aluminum tunnel ram, two 4bbl carbs, and stock iron heads? I know the combination is DEFINITELY adding a substantial amount of weight but does anybody actually know how much it is?

Looking for technical drawings

Hi,
I am fairly new in the topic :( and would like to ask if someone would know where i could get technical drawings from a 460 Block? Especially I would be interested in the Big End and the sides with the engine mounts.

Could anyone help?

Thank you!

Jens

Does any old 460 block work or is there a great one....

I just changed my mind for a street/strip drag mustang project and was wondering if anybody knows if there is a particular year of 460 that was superior in performance .... for example the early windsor's like 66-72 or something like that have really good rigidity strength and are the superior block when you are going to build a windsor for performance as opposed to the newer windsor blocks which tend to twist around 6 or 7 hundred hp just wondering. I know I could get bone stock 460 motor out of a old 89 F-350 for 500 and that is pretty reasonable since I could keep the crank block and heads.....

Stock for stock 460? I'd say 49 state pre 74 IMO. Everything after that had seriously retarded cam timing and low CR. Just swapping an early timing set into a 74 post 460 will wake it up big time but forget about passing emmisions with it, not that your probably worried about that anyway. I'd look for a 69/70 T-bird with a 429 Thunderjet. You'd surprised how many are still out there. I know where there's one right now for 1K for the entire car. http://bn.craigslist.org/cto/1618195505.html Before I built the stroker for my truck I had a fairly stock 429 TJ (intake, carb, headers, ign) that could shred my 29x15.5x15 MTs at will. I used a 429 TJ block for my stroker build as well. 1/2 price day at the U-Pull-It $75 bucks, can't beat that. If I'm not mistaken the TJ was rated at a conservative 370 hp but made a boat load of torque
