Just stripped my blown 354 for a check over (just brought the car) and the engine is in fair shape needs a bit but not too bad anyway while its apart thought I would put a set of rings in it amongst other things the pistons are flat top with valve reliefs the make is Bohnalite the part number up the inside is 1639222 and I cant find a reference to this anywhere! so if anyone has any info please message me or comment on this thread
Editing your title to something like "Need help with part number for 354 engine" will probably help you get some answers. Just the title "Help" is pretty generic and a lot of people may just scroll right past it.
The piston casting number indicates a factory part. You didn't mention but I'd guess that they are oversize. Bohnalite was one of many Mopar vendors. .
The main problem I've got is the guy that would have all the info I need is no longer with us the engine is in fair condition, mechanical cam but no numbers two bad lifters so renewing all from shnieder the bottom end is good just can't find what size the pistons are the same number is even stamped on the top I guess its going to be a trip.to the machine shop and get it measured
