My father has a complete 396 block that he was told was a 425 horse motor. I got a block number of 3855962 which seems to be a Z16 motor. If this motor is a complete minus an oe intake, does anyone know what this is worth or where to maybe list it for sale? Was running when pulled and supposedly had new valves with a fresh bore and HP pistons.
Thanks for any and all advice!
First, The engine, in a Chevelle, is IDENTICAL to the "375HP" 396 engine. Fullzise cars and the '65 Corvette were rated at 425 HP, and "possibly" some early '66 Chevelles. Chevelles had different and supposedly more restrictive exhaust manifolds, accounting for much of the disparity in the numbers.
The Z16 was a 375 HP engine.
WHY do you think this is a Z16 engine?
The 3855962 was used in 1965 (and 1966?) Fullsize cars (Impala, Biscayne, BelAir, etc with the 425HP/396 option, and (I think) the 1965 Corvette (396/425HP), as well as the '66 Chevelle 375 HP engines and an unknown number of '66 Chevelle 360HP engines...
The thing to do would be to look for the stamped engine sufix codes on the passenger-side front deck pad, and report those numbers back here to decipher it further...
Value? "Complete" except intake, and 'verifiably" in good condition (at least rebuildable), could be $2000-$12000+++ depending on who is looking, and just what the codes determine (date, original application, etc).
Get the cylinder haed casting numbers too...
