| Budget 406 Build Up Inside |
Subject: Budget 406 Build Up Inside by PeteK on 2009/10/31 14:36:15 Although it was a winter project, I decided to take advantage of the warmer weather and get a jump start on cleaning up all the parts and pieces to assemble the 406 I've had on the stand for about 5 years now. This build will use a 2 bolt main block, a cast scat crank, reconditioned GM rods (with ARP bolts), and a set of sealed power Hyper pistons. Cylinder heads will be a set of AFR 195 Eliminators, and a comp cams bumpstick (retro fit hydraulic roller). Pic below shows the block ready to receive the crankshaft. Block has alread been fully machined, cleaned and has the freeze plugs, cam bearings and oil galley plugs installed by me. I regret not snapping pics of the cam bearing installation. Most are afraid to install them in the home garage, but they are not a big deal, with the proper driver.

Thrust measures .0065 [IMG]http://i161.photobucket.com/albums/t221/vrodpete/100_5610.jpg[/IMG] Notice the 2 round slugs of mallory installed in the front counterweight. This makes the front of the crank neutral, so I can run an internal balanced, harmonic balancer. Rear of the crank is balanced to be the same as a typical GM 400 with an external flexplate.

I did mod the driver's side plug with a small hole, so it will pee oil on the timing chain and gearset. I will be running a Cloyes Hex-adjust timing set with a torrington bearing, so it is probably overkill. It hurts nothing though.
