Different Strokes late 70's / mid 80's

Here I go thinking again. I been thinking about a 360cr. Looking at the specs I found it's a 67mm stroke. I never gave it much thought. I always thought it was a smaller bore 390 with 71mm stroke.

250- 64mm stroke
360- 67mm stroke
390- 71mm stroke
420- 71mm stroke
400- 74mm stroke
430- 74mm stroke
500- 84mm stroke.

If you want to add any thoughts feel free.

The 360 and 390 piston sizes are in the same diameter range to the extent that a 2nd over 360 is std 390.

Interesting, sounds like the little 360 can hold its own.

Reminds me of the 283, 327, 350 and 400 small block chevys. As we go up we go from 10,000rpm to 7,500rpm in built engines. The smaller bores can hold there own.

10 Grand ! A small block chevy 400 red lines at 5500 ... wtf

a small block chev can rev to whatever your wallet allows..mine does 6000...

Big Bill...you must learn to turn that mind off at nite... thinking is bad for you...you might have ideas and we all know how much ideas can cost

A rollerized small block built to the hilt a 283/301/327 will turn 10k rpm wise. My bigblock I built redlined at 6,700rpm on the full body car dyno.(396/400+hp)

I would like to build one more car. Just to show my kids what real hp is like. They think these rice burners are fast. On a hole shot you feel the g's set you back in the seat then the slicks hooked up. Bang second, bang third, band fourth. The 12 second run goes by very fast.

Ima diesel guy myself, but some of those jap rides can turn out some serious h/p. Ever hear of the Nissan RB engines or the Toyota 2jz or the notorious Mazda wenkel rotary? These things with minor work could eat a mild built 350 depending on what car it's in. I'd never drive one personally as it's not my cup of tea but some the "rice" can be really fast. But on the other side of the fence there's no replacement for displacement. Twin turbo mopar big block would be the engine I'd build if a had a car to put one in.

Can't go wrong with a Cummins. Mouse motors can turn that high but a 400 sbc is set up like a diesel , all low end torque and lots of it.

The bigger bore / stroke rev less but the torque increases. I like the 283/301 with the roller setup.

My son had a Suzuki bandit 400cc she redlined at 17,000rpm. It's a 400gsxr engine detuned. Used a lot in Europe as beginner bikes. This little liquid cooled 400 was a rocket.

Dam BB I know its friday but its still a lil early , couple more hours for me and I'll be pop n tops too... lol

Howd you know I have a cummins lol 12 valve all the way!

a 12 second run takes about 12 seconds !

a mate yonks ago had a white hk Bathurst Monaro with a hot 327 in it used to pull 13.2 over the 1/4. ive got a blue one now
