**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?

**DeadheadNM** · 03-18-2021, 10:55 PM

Unequivocally NO small block 400.

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

**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...
