Hey guys,
I recently purchased a `69. I'm trying to identify the engine that came with it, and I have to say, I'm confused.

Casting number is: 3914638 which I found saying it was 68-69 327
ID Number: T0429DH which from what I can find has 3 options
DH 1958283 Powerglide 250 FI VetteDH 1965283 Powerglide 220 4 ChevelleDH 1968307 Powerglide - - full size

What in the world do I have?! Any suggestions?

 

You more than likely have a 307 there. Although casting # 3914638 comes up as a 327, so does it for a 307. I've heard that GM used those castings (underbored) to build some 307's. Is that so? The DH suffix code on your block seems to support it, as that stands for a 1968 307 with a powerglide. The other DH codes are for a 1958 and 1965 283, but those don't mesh with the casting #.

 

Probably not what he wanted to hear

 

Could try this link.

I have used this successfully in the past, although I just tried it and it said it was temporally off line and to try again later. Good Luck

 

Mortec has been "temporarily" off line for months now.

 

This is the new link for Mortec.

Thanks for the website update, and the info on the engine. True, not what I wanted, but it's good to know. Now I can look at putting something else in it's place!
