The numbers on that engine (with one exception) make perfect sense. With a casting date of 10/29/68 to engine would be for/from a 69 model year car. This would result in the letter code "E" preceding the displacement on the stampings ahead of the intake manifold. The seller says "F440" but the bottom of the "E was probably lightly stamped and therefore misinterpreted. The "11 11" stated by the seller make sense as well, being an engine assembly date about 2 weeks after the block casting date. Very normal, but I have seen some much, much further apart. The "HP2" simply indicates a HP engine built on shift 2, not some super special version of an HP engine. I've seen the shift 2 mark follow the assembly date as well, as shown with this 1970 Road Runner 383: http://bos-engel.com/MML/s383pad.JPG And here's the 426W out of a 65 Dodge Monaco: http://bos-engel.com/MML/engstamps_s.jpg I have yet to see any big block engine marked with the engine sequential number. Small blocks, yes, but not big blocks. The seller should include the VIN info stamped into the side of the block way down at the oil pan mating surface. For a 69 engine that would be the entire VIN of the vehicle it was installed in. He could have the engine out of a hot Super Bee, Road Runner, or GTX and make a muscle car owner very, very happy. http://bos-engel.com/MML/383vin.jpg Not much market for the engine the way he built it as reflected by the number of bids.

( was IML: 440 for cast iron trans) Reply-To: mailing-list@xxxxxxxxxxxxxxxx --0-1479696544-1178075103=:10572 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit That's not where the HP2 stamp is supposed to be. It should be up next to the numbers "440". Down there would be the sequential number of the engines built that day, easily modified to read "HP2", and any Maltese cross and/or "X" indicating undersize crankshaft. The "11 11" is the month and date of engine assembly, and the spacing in the bottom row can vary widely. In '69 there was no engine serial number per so the claim can't be verified. The HP motors had identically cast blocks, just different innards and bolt-ons. Since this is a full race rebuild, the innards are not original and therefor not stock "HP". caveat emptor ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
