Got all the pistons and rods in today. Plastigage check on each rod bearing clearance was .015. Rotational torque when all eight were installed was 300 inch pounds (25 ft lbs).

Installed the original camshaft back in the engine and degreed it. Since I didn't have a solid lifter to use for degreeing purposes, I wound up disassembling one of the original hydraulic lifters and replacing the inner spring with a 5/16 nut and and reassembling it. It worked great.
I reused the existing timing chain and gears since they had all of 400 miles on them (and 20 years since the dealer installed them). The factory intake centerline spec is 110 degrees and it turned out to be between 108.75 and 109 degrees. (after three readings). So I guess it is a little over one degree advanced which is perfectly fine with me. Here's the factory specs on the 460/365 horsepower camshaft: engine...............lobe lift.....valve lift.........open (btdc)... IN dur...EX dur....overlap.......hp.....................torque .........comp ratio 1971-460(4v).....253/.278...442/.486.......16 deg..........256.......270........36 deg .....(365hp@4600)[email protected] 256°/270° @ SAE 193°/206° @ .050" .253"/.278" lobe lift (.443/.487 valve lift) 110°/116° lobe centerlines – 113 Lobe Separation Angle Last edited by njsteve; 10-21-2018 at 10:18 AM. |

Still at it today. Measured the deck clearance with the dial indicator. Came out to .037. CC'd one of the chambers and got 74 cc's. Installed the cylinder heads, lifters, push rods and a new set of rocker arms. Then installed the intake. It weighs a ton! I think it was almost as heavy as one of the cylinder heads.
Worked out the calculations for compression ratio and it comes to 10.78 to 1. It should be "peppy" as Gramma used to say. |

Thanks!
BTW, in case anyone wonders, the VIN stamp on these blocks is on the rear of the block, just below where the driver's side cylinder heads bolts up. |
