Anyone ever see a 3-on-the-tree 400 4-bbl or 428/428 HO B-body? (Rhetorical question, I don't expect to get any responses...)

Dennis

The 3 on the tree wasn't available with the 400 4bbl but I have a 428-360 manual engine, which btw was in effect an HO engine less the long branch manifolds with 62 screw-in big valve heads, 067 cam, 4 bolt mains, windage tray, HO distributor and carb, none of which were on the 428-360 automatics which were basically a 428 with a 4bbl but otherwise built to 400-290 2bbl specs.

Sure about that?

'69 428 HO B body cars had a PC coded TH 400. The std unit for all others was coded PA or PB.

I do not know the exact differences but I think the HO PC units had a stronger sprag, might have had an extra clutch pack, probably had a different governor setting and different valve body shift points.

Std rear end for a 428 HO a/t B body was the 3.42:1. For some reason they listed a 3.23 for m/t cars but since they didn't make any I am not sure how accurate that is although it is probably applicable to GP's.

Dennis/SD455: PM me or better yet call me at 571 265 5950. I am leaving work in about 30 minutes and will be on my phone after that.

'69 428 HO's used several parts from the GTO bin.

7268 carb
1119 distributor
#62 heads: screw in studs, large valves, springs?
.067 cam
plus long branch manifolds

Did not know there was difference in the windage tray

To the best of my knowledge only 726 B body 428 HO's were built plus another 12xx for GP's for a total of just under 2000. That represents less than 1/2 of 1% of the total B body and G body production that year.

Diego, Now I am (lol). You really can't can't put a lot of faith in the factory printed materials.

Blubomber, I'll pm you later, busy with running around right now. Dennis

Hey Diego you said 135 68 gp 428 how cars were built . Is that stick and auto cars. If so is there any break down of 4 speed cars. Also I have a 68 428ho 4 speed ventura with a 4.11 posi manual steering and brakes what do you think maybe 1 of 20 built like that. Thanks for the info.

The 135 is for all transmissions.

If you give me the body code and option codes you've listed, I may be able to find out something. There's some interesting combinations that are listed that one wouldn't normally expect but generally I probably will only be able to find Catalina HO/stick for you....if the page is not missing from the Archives.

SD455SJ Nothing heard..

Bump....

Sorry I forgot to get you the information what do you need the Vin code I'll try and take a picture of the Phs too

Oh the PHS would be perfect!

I'd love to see it too.....Dennis

Just got the invoice from 4214speed so when I get the chance, I'll post it and any info I can gather.

Diego, Looking forward to seeing that. Dennis

Went to Carlisle, so I've been MIA. However, I took the time on the plane to restart compiling information that I started a few years ago.

I'll reply in full when I'm done in a few days, but here's some info (if it hasn't been stated yet):

173 Catalinas had the 428 HO
363 Cats had the M20, out of 2,546 with manual tranny in total (hence, the difference is the 3-speed).

I have some codes I need to translate (body and option) but it's progressing. One of the problems I have is that all the stats are from photos, and some of them are not clear. I want to make sure I don't post incorrect info or misunderstand how things are laid out.

Diego, Waiting with utmost anticipation to see what you find out.

Dennis

Cat
 

Sounds like the car I purchased from Pa. 68 Cat 2 door sedan 428 HO, close ratio 4 speed, 4:11 special order rear axle ratio, heavy duty battery, heavy duty cooling and fan, shoulder belts, bench seat, poverty caps with 15 inch wheels. Vedoro green with black cloth interior. Numbers matching. KC
