Sorry this is my first American truck.  Built a number of old Alfa Romeos and British iron.  Appreciate the input.  Would Chevy have called the 379 a 400?

did you google 379 sbc? apparently it is a replacement 350 but the dipstick can be located on either side for that "OEM" look.

I'm not sure I know what you mean by a "replacement" engine.  Appreciate some clarification. Try in figure out exactly what I've bought has been very frustrating.  I know the bed is fron a later truck by the tailgate and the fuel door.

VD212800 is not the casting number; it is the engine production code that IDs the year and vehicle application of the motor.

The "379" is the last three digits of the actual casting number, 14016379, which is a 1978 - 1985 small block 350 CID casting used in light-duty truck applications.  Since it is an unmachined casting ID number, the block was used as the base for both 2-bolt and 4-bolt engines.

Irish, casting dates are stamped numbers rather than cast.  Otherwise, casting molds would require modification for each production run.

New Question - with the 379 & Edlebrock (500 cfm) should I still run regular gas.  I hope as I'm getting about 7 mpg at the moment.

6.2 gas expectations
« Reply #22 on: June 09, 2017, 02:59:51 pm »
I have heard some disdainful postings about the 6.2.  I assume they were regarding the gas engine.  I have one in my recently purchased 76 sb.  it doesn't have a lot of grunt and the current mpg is somewhere about eight, 1403 Edlebrock (500 cfm) with dual exhaust.  What should I expect; durability? performance? mpg? I'm just learning, appreciate any insight.

Agreed it's a 350. 379 is the block casting number not the displacement. Since your vin says it came with a 400. Most likely a rebuilt or crate motor.

Again, not to be a jerk, but again, you DO NOT have a "379" engine.  No such gas engine exists as far what was available in this series of trucks.

i don't have time to get into detail, but perhaps this could help:
