Was a running block and crank up till this year, two sleeves were installed in 2010, running ever since. The bore is at 0.35 over. Block and crank are very clean, also have the end caps. $500, will need to be picked up not shipping this, sorry.

Also have the srp pistons and forged rods to go with this, also a sfi flywheel and a center force pressure plate...........pistons have a couple faint scratches on the side but nothing hits your finger nail, stop by im easy to deal with.

Located in Oshkosh, WI

My assumption is this was a later parts run as the part number is partially hand stamped.
Needs a polish but was stored in a dry basement. This will
Fit in any 421/428/455 block. Crank about is 1/2" shorter but the balancer registers on the crank gear. Match your timing cover to your balancer and everything works. Pics

These were the first open chamber design Pontiac heads with combustion chambers resembling later ram air heads. They are large valve heads with 2.11 intake valves and 1.77 exhaust. I measured a combustion chamber on each head at 77-78CC. Would be perfect for a performance 400 build.
These heads are in VGC and came off a running engine. I don’t believe the heads were ever off. Both heads are dated C227. No stuck valves, all threads look good and are not ported. Complete with valves, springs and rockers.
Asking $500 Local pickup in Brecksville Ohio or will deliver to Pontiac Nationals with a deposit.
