Figuring out my bore

[fyrmn14]

So I bought a banshee that the guy said had some bore work done. He said it is a 383 CC shee.

 

I am now trying to purchase a coolhead and wanting to figure out the exact boring.

 

Is there a calculation or something that I could figure out the new bore size off a cc measurment?

Best way to find out is to take the head off and measure the bore with an inside micrometer. Do a few checks in different places and heights in the bore. Only takes about a 1/2-hour from head on to off, measure bore then on again.

 

Good luck. :thumbsup:

67.25" bore, is the only way to come up with a 383cc motor.

 

Here's the calculation:

Bore x Bore x Stroke x 2 x 0.0007854 = cc's

67.25 x 67.25 x 54 x 2 x 0.0007854 = 383.61822345

Here's the calculation:

Bore x Bore x Stroke x 2 x 0.0007854 = cc's

67.25 x 67.25 x 54 x 2 x 0.0007854 = 383.61822345

 

Thank you stroker, that was exactly what I was looking for.

What he is getting at is the Banshee piston over sizes only go to 66.00mm meaning you do not have a 383 unless you have big bore sleeves or a stroked motor.

If I was a mechanic and didn't suck at math I would prolly understand that shit. lol
