Don't you have to bore and stroke to get to 360?

Yes, I think .060" overbore with a 1/4" stroker gets you 365 cid If I remember correctly!

But that's about as far as you can go - cylinder walls getting a tad thin at that point. Think about it - you're overboring a 13/16" cylinder to .8725 which is pretty close to 7/8" (or 14/16" if you prefer).

I really don't think I'd want to use that much of an overbore on a street machine.

This is without a doubt a fine looking car But for 45K, I would not expect to have to fix a flat or bent fender or scratches, or install trim. Maybe I'm too picky, and it is a moot subject anyway, since I don't have the money to buy it.
I'm not badmouthing the car, what work was done looks to be very professionaly done. Just giving MY OPINION, and if you combine it with a $5 dollar bill You MIGHT be able to buy a cup of coffee!

Actually, .060 with 1/2 inch stroke will get you 353.2 cu in. Bored .125 with 1/2 stroke will get you 365.2 cu in. Always stay with a smaller bore. You lose to much in cylinder stability, gasket overhang, blowing compression into the cooling system, etc. going over .080. I'm running .060 in my race car and have the best time of 12.63 @ 101 mph. Have not been out yet this year, maybe this weekend. You make power with your cam, compression, and air flow.

At 45K the only thing you will hear over at that auction is the crickets chirping..... :dry:

My street driven 53 is .100 over and runs real nice, a bit hard to start with 6v, but an 8v tractor battery and an adjustable voltage reg does the trick!

Let's see - 13/16" is .8125"; add .100 - .9125. So .100 over is up around 59/64. Don't add up.

Did you mean .010, by chance. .100 over you wouldn't have any cylinder walls left. Be one hell of a piston to fit that. :woohoo:

Actually Alex it will add up. You can get aftermarket pistons .100 3.9125 (bore) and you can get chev. or chrysler rings and file fit OR order the pistons .0025 bigger to 3.915 (bore) and the rings (.040) will fit pecfectly. I've gone .125 over (not recommended).

randy: this is baby huey65, I was wondering what kind of race car you have? Is it a hudson? back in the sixties me and another guy race a54 jet we bought from Ike Smith in ca. It was 1/2" strocker and 62 over, we ran chevy pistons.
We ran in J gas class. we still have the motor but the body got a way. I'm thinking of getting anotherjet 2dr put in the strocker for cruisin. We thoght that a 1/2" strocker and 62 over was 355ci. I saw some pictures from alburn meet, there was a guy had anold stock car that had 387ci on the hood. How would you get that? this is my first posting, hope I'm not runing on to much.the guy I was partners with back then has the real green hornt.

Yes, I run a 41 Hudson Coupe .060 Ross Pistons, 1/2 inch stroker, and 3 side draft webers. Best to date is 12:63 @ 101 mph. Have not run it this year but may go out this weekend and run 1/8 mile. The 387 cu in is probably a 5 1/8 stroker. Ran one once and did not gain anything over the 5 inch. Send me you email and I will send a picture.

Walt here; If you want to drag race build an engine that will RPM. A stroker is only good for torque but slow to RPM. Bore a 308 out to 60 over, install a 232 crank, use twin-h set up, open main jets to .003 oversize, open accelerator pump jet .002 over size and that engine will turn to 6,000 RPM's and with a low gear in the rear, you will shock a lot of people. This is the way we used to race our 34 Hudson coupe back in the 50's and we were told many times, don't bring that car here. Never lost a race. Build one and you will see. Walt.

Guys, what does a standard stroke 308 with .060 over become in cubic inches?

[Deleted User]

317.5 CID Walt.

I believe there is no substitue for cubic inches. Meet me at the "tree"

Try driving it across the country, ocean to ocean, like I have 12 times. Walt.

I'm sure that was the point when they bought them off the showroom floor, that any hudson could go across the US many times and you proved there point.

We are taking about horsepower at a track.

I'm sorry I didn't catch your 1/4 mile time when you raced the RPM motor? Care to share

Never raced the 1/4 mile, all my racing was oval tracks, 1/5,1/4,1/2, 3/4 and 5/8's. Won many races on them all. Also my V-8 60 midget in 1956 I set the fasted time at Daytona Beach's flying mile, 118.4 MPH. Beat all the Offies and they were mad, how can a V-8. 60 Ford engine beat Offies. Engine work, how do youthink I drive my Hornet across country in the 70 to 90 and a few time over the 100 mark. Can cover over 500 miles a day and now with 135,000 miles in 12 years still run like a charm. Any body in the NOR-CAL Chapter can tell you this. Walt.
