I was wondering how rare a 69 Bonneville Brougham is with 428 HO. I’m looking at one for sale. Has every option except disc brakes, atc air and custom sport wood wheel . Midnight green white vinyl top green interior

All I can tell you is that 549 Bonnevilles had the 428 HO. Of the big cars, it was the most popular recipient for that engine. This is from a hand-typed table found at the GM Heritage Center. If there's more specific info, I haven't seen it.

In total, 715 big cars came with that engine.

Can't tell you how many but I bought one back in the mid 80's to build the 428 HO for my race car. It had long branch manifolds and cast 62 heads. Car was loaded with options power locks (vacuum operated) windows, seat, antenna, steering, brakes, climate control, cruise, defrost, am-fm, cornering lights, tilt wheel, posi, and more. It was a Brougham with green cloth interior and green exterior (what was not rusted or painted primer black). Paid $500 for it and drove it home. Pulled motor (4 bolt mains) and built a 428 .030 over with 1970 RA IV heads (614), Warrior intake and Holley 800cfm. If had not been so rusty would have been a cool car to restore. Also bought a 67 2+2 428 car around the same time and parted that one out too. I have not seen another 69 428 HO Brougham since then.

Also there were 3 versions of the 428 in 1969. One with small valve heads. Next step up was large valve heads. Then top dog was the HO with large valve heads and long branch manifolds. Each had their own camshaft matched to horsepower rating.

Thanks for the info. 428 HO Bonneville Brougham would be a good daily cruiser. Loaded unlike my GP

There is a thread here “70 Bonneville, I drug home”, it’s a rust ball hulk, has a posi rear and front disc brakes. I am sure the price would be fair, although it’s a long ways off, sounds like it’s parts would make your (“If”) car a much better/safer driver.

I haven’t pulled trigger on it yet but seriously thinking about it... do I really NEED another project???

[77 TRASHCAN]

Depends upon how you take it all in... maybe. The car you are considering, sounds like a solid great car. May need some TLC, fluid replacements, etc. buy the parts car yank and rebuild the front and rear end pieces, rebuild those components to swap another day...
