JC's Automotive Trivia Thread

On the Buick oddfire V6...it was odd fire because the firing impulses were not spaced evenly, like a V8 or inline 6. Dunno what it was based on, Buick 350V8?

Close, the first ones were based on the Buick 215 V8

 

Here's one :: what was the Buick V-6 odd fire modeled from and why is it a ODDFIRE?

It was modeled from the Buick 225 V6 which saw service in early Jeeps, Buick manufactured these V6's along the same assembly line as the Buick 350.

The crank throws were offset on these engines to make a more balanced engine, this was done to reduce the secondary shaking forces inherent in the 60 dgree V6.

GM first had disc brakes on the Corvette in 1965. And 4-wheel discs too! And get this...there was a 'disc-brake delete' option in '65

Initially, when I read of the disc-brake delete, I thought of the drag racing application of drum brakes. Except, Corvette's were never that big in the drag circuit, were they?

Huh? The crankpins were not split on the oddfire engines, that's why they're 'oddfire'. The later ('77?) 'even fire' V6s had the split crankpins to even out the firing impulses. And the Buick V6s were 90 degree engines, not 60 degree.

Had your coffee yet today, Roger?

If the Tucker had gone into production, that date would have been 1947

Wow, I had no idea the airbag was that old. I would've guessed late eighties! [/quote]

He's talking about seatbelts. The Tucker would have had seatbelts in 1947.

Yes, I know. The airbag and seatbelt questions were together

Next....what was the last year you could order a big-block in a Corvette?

1969 .....?

GM first had disc brakes on the Corvette in 1965. And 4-wheel discs too! And get this...there was a 'disc-brake delete' option in '65

Other GM models had discs available starting in 1967.

Learn your history boy, the Crosly of the fifties had the first American Disc brakes.

It might be 63... maybe a 396?
67 Vette was the most badass... 427!!!

heh, so it's not '63 427 is a big block.
iirc, they ran the 427 through '69.

lol! I meant a REAL car, not a go-kart


In 1965, 316 people were silly enough to delete the 4W disc brakes in favor (?) of the 4W drum brakes


As far as the big block Corvettes, 1965 was the first year (396/425hp), and 1974 was the last year (454/270hp)

Let's switch gears here. Early (mid- 60s) Hondas, like the S500 and S600, had some interesting design features, like twin cams, needle-bearing crankshafts (and 9500RPM redlines, eat your heart
out, S2000!). What was interesting about the rear-axle setup?
