Here's what I'm running:

original 1969 YS code 400 (+.040) = 408 CID
oil holes/casting ridges ground smooth for drainback/aligned honed
Original nodular crank, stock stroke, .010/.010.
Eagle H-beam 4340 steel rods 6.625 (stock length)
Speed Pro Forged pistons (coated skirts)
Arp rod bolts and main stud kit
Speed pro Rings
Factory deck -zeroed
Cloyes true roller timing chain
Clevite bearings (cam/main/rods)
rotate assembly balanced
Comp Cams XE-274 Cam .488/.491 lift/matching lifters
Harland sharp full rolller rockers. 1.5:1 ratio
Comp cams factory length pushrods.
edelbrock Performer Heads 87 cc/planed, slightly stiffer springs installed
10.6:1 compression
perfromer RPM intake/planed to match intake
Dougs 1-7/8" full length headers, 3 1/2 collectors, 2-1/2 mandrel bent exhaust, X-pipe
Holley 750 Vaccum secondary/dual feed carb
Pertronix HEI with Accel wires.
Moroso 8 quart pan
Factory windage tray
Brad penn break in oil (will be changed within next 3 weeks)

TH400 PX code (factory)
Rebuilt, shift kit.
2500 RPM stall converter
Factory open 8.2" 10 bolt with 3:23 gears

The carb is still out of the box tune and the timing will get played with once I change the break-in oil.

Still, with 6-year-old 215-65-15 well-used michelin radials on the back of this thing traction is only a dream.

Otherwise car looks like a well worn car that sat in a shed since 1983 (which it did)
