Let's see a picture!

All Pontiac blocks from 287 thru 455 are the same physical size, so there are no big or small blocks.

There were two 400's offered in the '69 Bonnie. The engine codes (stamped with the VIN, located on the passenger side of the block) are: YA and YB. Both offer 265HP, 8.6:1 compression and 2 bl carb.

The 428 engines had the HP in that year - from 340-390.

They would be: WG - 340HP (manual shift)
WJ - 390HP (manual shift)
YH - 360HP (auto)
YK - 390HP (auto)
YL - 360HP (manual shift)

ok ill try to get you a picture tommorow. the carb is a 4 barrel and the prev owner said it would push 360 hp. but what he says and it does are two diffrent things.

Ahh Sorry I Just Noticed I Said 69 But The Engine Is An 1968 Sorry

congratualtions on your purchase!

To be sure I was clear, I meant a picture of the car, not the engine :)

The '68 is quite a bit different:

WE - 340HP (MANUAL) CR 10.5:1 4 bl.
YE - 340HP (AUTO) CR 10.5:1 4 bl.
YA - 265HP (AUTO) CR 8.6:1 2 bl.
