hmm okay ..like i said ..i was told it was a mystery motor ..supposedlly only a few were made...i was also told it was a hi-perf version
with some goodies added by factory ..balanced ,blueprinted..,tolerances,clearances.valve lash...parts..??)i really dont know ..most people say it is a 215 which i have come to believe ..but what about this mystery or prototype..?? motor...

my block has been stamped JN 455 .. i think i came across somewhere that this was a hi perf stamp..??

i just would like to know if it is ..i dont want to buy parts that are not applicable or maybe screw up something.. ??

:confused:

JN designates it as a 63 4bbl high performance 215. It had higher compression (11:1) vs. the 2bbl 215 (9:1). Check the years info under the Buicks.net logo above for more information on the 63 215.

I think you may have a T-10 trans, but there should be flange near the front stamped with some identification. It should start with a letter and is about 1/4" tall. If you can find those We can decode it for sure.

hmnmm..nice so i have the hi perf motor as chuck said ....ok now i know what it is ..anyone know any thing else bout this mystery motor .. ??

steve..the only numbers i didnt list was a stamping of P 0121 .. ???

thanks for the insight and help...i wonder if there was any lit about this motor ..??
did this motor come with a muncie t-10 ..??
can u figure out what year (tranny) is ..??

hey bob i guess u now can correct that error or sumbit it anyhow to the higher ups ...if what is told is true i guess i do have a 1963 buick 215 hi perf block stamping 11993724 those xxx can be finally corrected smile.gif

thanks all for your help and info
