need help with eng. I.D.
I bought a 73 Camaro with what I was told had a 454 in it. Now I would like to verify the numbers.
R/side eng pad 7 TF7111700 S
driver side rear 361959
rear of block just right of cam Hi Per Pass
rear of eng L/side of cam F
7
middle of left side of eng. on middle bellhousing mounting boss GM T12
The engine has a 4.2500 bore and a 4.00 stroke.
With the pistons at TDC they are even with the top of deck.
It appears to have cast internals. Not sure.
Double roller chain
Head #s
122 76
GM9T
PASS X
336781
Left side has all similar#s except
GM12T
The heads are of a open chamber config. as I understand it.
Triple valve springs with stamped roller rockers.
I can send any pics nessasary, on request.
Thanks in advance.
