engine decode check me on this!
Guys I bought an engine today that I was told was a 327 and I think it is a 327 by the codes, but some are confusing, check me on this. I am using the 1965-1969 Alan Colvin book for reference.
Engine pad 18S231267 (st louis- pass car)
T0719HH (Tonawanda, July 19,) (HH, no 1968 HH code in my book)
There is a 1969 pass 350/300 hp HH code for HP, turbo 400 application?
engine casting # 3914660 (68 pass 327/275 hp application)
Engine casting date- G8 8 (July 8, 68)
Crankshaft casting 3941174 (book says 327 68-72) but the flange shape at rear end looks like 350 crank flange?
2 bolt mains, not forged.
Heads casting # 3947041 (69 350/300 hp application same as 461 except accessory holes added)
casting date- G13 8 (July 13 1968)
I think it is a 327 except for the crankshaft flange shape, and I can find no HH suffix codes for 68 Pass car. All the casting codes seem to match up as as if all parts were born together. Also since this is a late 68 engine could they have applied the 69 HH suffix to this engine?
What do you guys think? Since this seems to be a very late Pass car engine for the model year. Could the factory have added the 350 application heads as the 327 heads ran out, and the factory might of been starting the 69 350 stuff?
Thanks for any info. JW
