**StingRay** · 03-18-2021, 10:27 PM

No is the correct answer. 402 badged as a 400 but 402 cu in.

xs-cash · 03-18-2021, 10:34 PM

I believe so , yes

mr.mud1 · 03-18-2021, 10:48 PM

Kinda split on the answers here so far...

Killer Bee · 03-18-2021, 10:51 PM

no on the 400 sbc, it was offered only in passenger cars until somewhere around 76-77

engine option literature I believe will support that - Keith, little help here please?

This is correct. The 8-400 was a big block.

You are correct. GM spend $ on the marketing and didn't want everyone to think it was and different. The emissions requirements changed that year. The amount of pollutants was split into two categories. Under 400 CI and over 400 CI. By increasing the displacement the BBC fell into the over category and didn't require major reworking to meet the requirement. That's the reason for the displacement change.

**DeadheadNM** · 03-18-2021, 10:55 PM

Unequivocally NO small block 400.

**3757chevy** · 03-18-2021, 11:15 PM

My '71 had 400 badges, 402 emission label and the suffix code on the block said it was a 396.

TurboThrift · 03-18-2021, 11:40 PM

No, a 400 sbc wasn't an option in a 67-72 truck.

**leddzepp** · 03-18-2021, 11:48 PM

No

68 P.O.S. · 03-18-2021, 11:53 PM

No

**kwmech** · 03-19-2021, 01:29 AM

x10 in the no section, not 'till the mid 70s in the trucks

**MJN** · 03-19-2021, 08:03 AM

No, 400 SBC was not available for '72 C-10's. The 402 BBC was marketed as a 400.
https://www.gmheritagecenter.com/doc...olet-Truck.pdf

The 400 small block showed up in trucks in '76 but not in 2wd trucks, only 4wd's. Then in 1980 it was dropped from the 1/2tons and offered on K20/K30's with GVW greater than 8500 lbs. 1980 was also the last year of the 400 in trucks.

**Ol Blue K20** · 03-19-2021, 08:08 AM

I'll add my .02 worth. No 400 small blocks in 72 trucks!!!

briscuba · 03-20-2021, 01:08 PM

Some very good info in this thread. I owned a 1970 shorty with the stock 402 BB, never heard of a 400 SB for those early years. As a matter of fact, I believe the floor "hump" was raised to accommodate the larger block and Turbo 400.

My 2 cents...
