Cadillac Flathead 322 & 346

[@vincentconsolo5782]

Cadillac not only built the motors , but , they also built tanks as well !

[@myrenkohlhorst4422]

That distributor is at least a 1940 and up. No vacuum advance 39 and back. 322 used the carter carb and Cadillac used the Stromberg. The heat riser on LaSalle was on left manifold and Cadillac was on the right. I'd say that's a LaSalle 322 but you'll know when you measure the bore. Both. the 322 and 346 used the same fuel pump/vacuum pump arrangement. The rear view of the block shows the lifter gally vaper tube which is routed down thru the block to the draft tube which pulls air in thru the bottom of the dip stick tube breather which was there attempt of vapers in block. You can tell the years of engine by block numbers and the head years by the raised gussets across heads. Very bad design on the fuel pump and exhaust manifolds. Causes fuel vaporization on shutdown where they have a drip tube to route the gas vapers from the carb bowl as they condense and drip by the left of the bell housing.

@myrenkoklhorst4422 Maybe you could answer a question that I've had for nearly 50 years. I "backyard" restored a '40 Cadillac way back in 1975. The engine had a 2 cracked pistons, could not find replacements. However, found a badly wrecked '37 Cadillac Hearse and I pulled the pistons out of. While the pistons mic'd out the same, they had an additional compression ring (4 ring piston). I used them anyway (along with their rings), ran just fine. Could never figure out what or why?

[@sandasturner9529]

​@@ransomholbrook7428 maybe that fourth rimg is for additional engine life and additional compression and possibly more induction as well. Usually race cars are the only vehicles are fitted eith three or more compression rings. The case you have made here leads me to believe yhose extra compression rings were added to that engine as per Cadillac's obsession with not cutting corners, Cadillac loved to over build things back then.

Thanks for posting this video. I've been wondering if GM made any flathead v8s at all. Never too old to learn something new about something older than you are hahaha

[@briankinnear7461]

Great video. Lots of info and tips. Be safe and stay well.

[@WiredCustomsSpeedShop]

Thank you, you too!

[@sickcoy13]

I had a 346 in a 1936 Chevy pick up. Loved the porcelain exhaust manifolds.

[@WiredCustomsSpeedShop]

That’s awesome, I’ve seen some old dingy motors with beautiful exhaust manifolds, hard to beat porcelain

[@m.a.p.4hp737]

Thank you for all the info. Very informative!

[@WiredCustomsSpeedShop]

No problem thank you for watching

[@captainamerica9353]

Nice to see your interest in this. Cadillac made the first mass-produced V8's, years before Ford. The Fords were better known, being in more common and less expensive cars.

[@coupster5464]

Hi @captainamerica9353.. and the Flat Caddys go real well in 1935 Fords.. this was originally a 2.5 ton truck, rather changed now.. Caddy has an overbore and the B&M blower kzbin.info/www/bejne/poGUhJuDfqacnNksi=zDQL0LWZEGQuoznu

[@sandrapoyner1353]

When used in tanks they had water cooled Hydroglide trans

[@sandrapoyner1353]

Sorry Hydromatic 👍👍👍👍🇦🇺🤗

[@danielbuckner2167]

I love these old cad engines. I always wonder why people didn't run turbo on these as it seems almost like it was designed to have one added!

[@chuckb9867]

Great finds zach super cool

[@WiredCustomsSpeedShop]

Thanks Chuck I appreciate it

[@davidpowell3347]

Does it have 5 main bearings instead of the 3 of the early Ford V8 ? I believe in its day was considered to be one of the best engines in cars (Cadillac/LaSalle) would have been compared against Packard's 9 main bearing Straight Eights these engines seem to have been forgotten after the OHV engines appeared

[@markpatterson7070]

The bottom of the fuel pump is a vacuum pump for the wipers

[@DaveMcLain]

Neat. Cadillac went to overhead valve in 1949. Did any of the parts remain the same?

[@WiredCustomsSpeedShop]

No idea Dave that’s a really good question

[@coupster5464]

@@WiredCustomsSpeedShop Nope

Where's Zack? We need a Christmas video.

[@WiredCustomsSpeedShop]

Hi Chuck! I’ve been working overtime to pay for my garage expansion! Just been keeping my head down and burning the candle at both ends lol

[@ManiacRacing]

Say what you will, it's damned hard to beat a Caddy flathead for cool factor, regardless of displacement. Triple that when it's blown!

[@WiredCustomsSpeedShop]

Yes they definitely have the cool factor!

[@coupster5464]

Hi there @ManiacRacing.. Flat Caddy's.. you might be interested in this one.. overbored to 362 cuin, 8.5 to 1 static comp plus B&M blower.. the '35 pickup was a 2.5 ton truck.. been in the framily since 1939 kzbin.info/www/bejne/poGUhJuDfqacnNksi=zDQL0LWZEGQuoznu

[@orbitup]

The fuel pump is also a vacuum pump (on the bottom) that's why it's so big.

[@WiredCustomsSpeedShop]

Killer! What did the car use it for?

[@orbitup]

@@WiredCustomsSpeedShop Wipers and maybe the grille shutters. The power windows were hydraulic! I only have the engine, it's not in a Cadillac.

[@tbiker99]

What is the weight difference between the caddy and Ford flatheads?

[@billbosco2349]

i think close to 200 lbs ! i think that's one of the main reasons they didn't hot rod too many of them

[@chuckb9867]

I'm first now I'll go watch the video

Henry Ford started caddillac

[@richceglinski7543]

No Henry Leland did. Then he sold it to General Motors and later founded Lincoln with his son. When it was going bankrupt also Henry Ford bought it for a bargain.
