We need a straight 8 thread!:)

[littlemo]

Didn't some early make of automobile have a straight 12 cyl. flathead engine ?? Maybe Buick or Cadillac ???

[Young Ed]

Not straight 12s that I know of. V12s and I think even v16s.

[meadowbrook]

I wonder if someone has a sound file of a straight 8, would love to hear them purr.

THIS JUST IN !THE ENGINE TURNS OVER...WELL AT LEAST IT'S NOT STUCK ANYWAY!

I put my crank handle to good use and the crank turns over..and i hear some compression but need to do a compression check next to make sure it has enough:)

Cool, now get off of the puter and go get her running...start out by charging the battery and checking for spark...seafoam or marvel mystery oil to loosen things up if need be, new plugs and gas{maybe a temporary gas can on the side} and lets here that she's running!

I am running a bit on a side track here, just starter surfing off from benny's utube link...

...found this Packard video...

I love each sound on that clip: The straight eight running, door closing, gear lever ... exhaust is leaking, but never mind...

[Uncle-Pekka]

Keep running side roads...

...another straight 8 classic: 1949 Buick fireball: FABULOUS SOUNDS!

Dad had a '48 New Yorker wit a flat 8. More powerful and smoother than my flat six. Great car to drive. I replaced the manifold gaskets and I swear that Intake / exhaust manifold weighed as much as a complete 4 cylinder engine. LOL

A few posts back there was talk of the need to build the crank up to take std bearings. There is another option. Save your old bearings, they can be rebuilt and line bored to fit your reground crank.

Not straight 12s that I know of. V12s and I think even v16s.

V-12 engines were offered by Packard, Pierce-Arrow, Cadillac, Lincoln, Auburn, Franklin and others. Franklin's engines were air cooled.

Packard was the first (1915) to offer a V-12 while the last V-12 was the 1948 Lincoln. Weidely, an American engine bulder, offered a 389.5-cid V-12 that was used by a number of small firms in the 1916-1922 period.

V-16 engines were offered by two firms - Cadillac and Marmon. Marmon (1931-33, 490.8-cid)) used an aluminum block while Cadillac actually had two V16 engines. The 1930 to 1937 engine was an ohv engine (452.4-cd), just like the V12 of the same era, while the 1938-1940 V-16 (431.4-cid) was a flathead engine.

I believe Packard played with the idea of straight 12, but only one prototype was built and the idea was quickly dropped.

I think the Chrysler 8 was more related to the Plymouth six than the 25 inch motors. I have seen a lot of the Packard eights, few New Yorkers. I don't think the Packard 327 made any more power than the Chrysler 8. Some Packards had nine main bearings, the crankshaft must have been very heavy

[Plymouthy Adams]

the Packard straight eight was a bit more pwerful, some 15 HP Chry. 135 and the Packard 150 (Packard being the 327 variant) Further, a number of Packard straight 8's were fitted with hydraulic lifters..last time I saw a Packard straight 8 running..yesterday..odd thing is the 9 bearing Packard was still rated at the same HP as the other..I think the 400 series saw the 9 bearing engines..not that up on Packard..

Nice....cept maybe that GM alt...hehehe...could've been a mopar unit instead. I like that spark plug cover assembly...neat.

While your waiting for the keys to get cut you could just hot wire it...leads connected via alligator clips or something...and no, we're not impatient or anything.

{did I mention I love straight 8s...?}

yea ..my uncle gave me the same advice. i'll get out there soon..i also got an off topic plymouth that i'm trying to get running because its's out side..and i need a 2nd car...

[Rusty O'Toole]

On the straight 12 question... some very large six cylinder engines had dual ignition. Pierce Arrow used such an engine up to 1928. Rolls Royce, McFarlan, and other luxury cars had them as well. Nash made dual ignition straight six and straight eight engines up to the early 40s.

Someone who saw one of the huge pre 1920 straight sixes, with over 500 cu in and cylinders cast in pairs might mistake it for a straight 12.

Eccentric auto maker Gabriel Voisin drew up a straight 12 model in the mid thirties. It had 2 of his straight six engines end to end and a strange drive system using connecting rods in place of a drive shaft. Somehow I doubt it was ever built.

[moparbenny]

had both lights working but then..the pass side burnt out:( i guess been sitting so long it didn't know what do do with it's self?

Nice to see a staight-8 thread on here! I spend most of my time lurking as I'm more into '60s mopars, but picked up a '49 New Yorker club

coupe with an 8 about a year ago- and have been learning more about them since.

This '49 is a great daily driver with 43k miles on it - all original drivetrain and everything works.

I'd love to hear more about what others know about tuning these motors -anybody been able to get good (better than 11) mileage with the BB 1bbl and fluid drive? Any way to split the exahust manifold (doesn't look easy).

That '33 isn't something you see everyday! Hope to hear you have it running soon.

[michael.warshaw]

looking for a straight 8 manifold if anyone has one pm me .

[Dodgeb4ya]

Frank Mitchell listed a NOS center section on Fleabay for the 1946-50 eights Mike. It's only $2250.00-if it has not sold. He might have sold it though. I'll sell a used complete one for $2700.00. They are really hard to find with no cracks and really hard to remove.

I bought a manifold for my 8 last year from a salvage yard in the Midwest ,it was $400 but shipping it was another $400 to London ,fitting it was a nightmare ,took days and the centre section cracked too! EVentually fitted and silent ,such a difference !
