What do you know about 427's?
I finally ID'ed my engine and it turns out to be a 427 Chevy Tall Block. I found a lot of stuff at www.MORTEC.com but not as much as I might like to know. Here's what I have:
Block: 473478 (427 Tall Block - 4 Bolt Main)
Casting Date: K 1 78 (November 1, 1978 (the 8 is fuzzy))
Next to casting date: Marine GM8
Inside the BellHousing: Drivers side - "F" Passengers - "TRUCK"
Drivers Side over oil filter housing: Truck 7 (Upside-Down)
Head Casting Number: 343772 (427 heads)
Inside, Top, Front of head: 26 74
Behind that: GM4T
Behind that: GMC
How good is this engine? What are it's weaknesses? Can anyone tell me what vehicle this came out of? Thanks!Last edited by Littleport22; 11-07-2005 at 08:19 AM.
It's not really work unless you'd rather be doing something else!

It's going into a 41 ford Pickup like the one in my avatar. Tons of vertical space under the hood and because it's a rod, I don't mind chopping up the inner fender wells if I have to. I could have some manufactured, but I don't think I'll need to. These old trucks are pretty roomy.It's not really work unless you'd rather be doing something else!

Does the "Marine GM8" stamp mean it came out of some kind of boat at all? Or is that a standard stamp?It's not really work unless you'd rather be doing something else!
