Mustang engine I.D. Help

[hunting4bear]

quick easy point pkrwud those are only difference in firing order switching those 4 wires. but i am seeing some funky casting number pointing to maybe hotrod may have a 351 not a 302 as he was originally told

I did find out some more info also if those numbers off cast are correct

HOTROD you said first 4 numbers off block were D8V8 could this be D8VE maybe well anyways
D = 1970's
8 = 78 - 79 production year
V= lincoln car motor was original being built for
E would be engine group (i show no 8 for 4th digit used in cast numbers in my info i have here in a book)

6015 is engine block

and the last 4 digit are design change data info


atleast we can help him in firing orders both ways weather its 302 or 351 :-)

i'm placing my beating money on the 351 for possible motor tho
