engine numbers

I have a 67 camaro. I'm trying to see engine block numbers without removing tranny bracket. It's supposed to be a 327 with a power glide.

Re: engine numbers

there is a great book
"chevy by the numbers"
that help you id almost everything gm
built from 1965 to 1969
but those numbers on the back of the block is
best way, you also can id heads by pulling valve cover
and of course crank also
you can have a block that says 350 but
is running 327 crank

good luck jay

Re: engine numbers

Get the numbers off the engine and transmssion here :http://www.camaros.org/drivetrain.shtml and post them. Then we can tell you exactly what you have.

You have the exact same problem I have, the casting numbers on the back of the block (drivers side) at the back bottom of the head are hidden by -what I think it is- the powerglide's kickdown cable bracket, the space in there is so tight that you can not see more than the GM mark (frustrating) the only thing you have left is the engine assembly date and suffix code stamped on the front pad infront of the drivers side head. Mine is TI0I3MM: T=Tonawanda plant I0=October I3= 13th day of the month and MM stands for 327/275 hp (L30) with Powerglide transmission. On the cowl tag I have 10=October and D=4th week, so far so good. Other than that I took the head casting numbers which are 3890462, and all I could find about them is that they are double hump heads used in 327 and 350 engines between '64 and '67 and they could be either 2.02/1.60 or 1.94/1.50 64cc, I guess I won't know that either untill I take engine appart.
Luckily I am pulling the engine and transmission for a complete overhaul in the next couple of weeks, but after loosing a pound or two between swet and skin of my hands and knuckles that is as far as I got with the numbers.
Here is where I found out about my heads: http://www.thedirtforum.com/castings.htm
and here is the info on the assembly plant/date/suffix:
http://www.chevy-camaro.com/chevy-ca...oding-help.asp
http://www.camaros.org/drivetrain.shtml#PadStamps
According to the last one in 1967 there were 2 types of L30's MM=automatic and MK=3 or 4 speed manual
To all of you knowledgeable people reading these posts please correct me if I am wrong, because so far this is the only thing (aside from my hope) that my engine is matching to my car taht is until I pull it out anyway.
