What is my Engine?
From the number 3896944 I deduced it is a 283.
Does the other casting tell us the date?

Re: What is my Engine?
Doing more research on this site:
http://chevellestuff.net/qd/block_casting_by_year.htm 3896944 1967 283 195 Tonawanda cast block was used only for the 1967 model year and was the last 283 design. . Maybe my block was cast July 1966 and then used in a 1967 vehicle?

Re: What is my Engine?
The casting date is in the second pic - is it C76? That should translate to March 7th of '66.

Re: What is my Engine?
Yes, I'm pretty sure now that it was cast in 66. The part that was confusing me was most sites were putting the 3896944 as a 1967 engine, but because it's either G76 or C76 it must have been put in a 67 that was built in 66. Kinda like my 2010 CRV I bought in 2009.

Re: What is my Engine?
March of '66 is pretty early to be correct for a '67. July is probably possible but someone sharper on such things than me will have to confirm.

Re: What is my Engine?
The casting date is just that, the day it was cast. That does not mean that it was machined and assembled right away. Whether it is a '66 or a '67 makes no difference IMO.

What I do gather from all this is the motor isn't the one my 65 would have originally came with.

Re: What is my Engine?
No, just was curious if what I have is the original engine that came with my 65.
I see now it's not.

Re: What is my Engine?
Was the original '65 283 in the truck when you sold it years ago?

It had a 283, but I never really paid any attention to block numbers and such back then. I was 17 years old then.

Re: What is my Engine?
I figured out this week that the heads on my 283 are 305 heads.

Re: What is my Engine?
Not just any 305 heads. The 416 heads are off the high output motor. They are the ones you want. I use them myself on the 283 in my '66.
