Boring questionsss

[twincat800]

I got some parts from a guy and he gave me what he said was a 513kit, a piston and cylinder. Would i have to bore the bottom end for that to fit???

you shouldnt have to just the oversized piton to fit the bore and the cylinder, and hook the wrist pin on put the piston on and cylinder and see if it fits from the sound of it it should.

well i got an edelbrock carb from a guy and he gave me this bore with it, its basically a bolt on, the pistons already in the cylinder... anyone else think this would be okay?? becasause i dont want to tear down the engine if this wont work...

What in the bottom end are you going to bore? If the jug and piston came off a 400 then your good to go not sure where the 513 came from?

the guy said it was a 513cc jug and piston... its a je piston and i think the number under the piston was 933mm or 993mm, something like that and i cant see that on je pistons website to see how big it actually is.. but the jug is the same as my stock 400. I would like to know what it is if in case i decide to put it on..

(i know its not actually 933 or 993 millimeters big haha thats just what the number was at the botton of the piston, but i be able to tell you for sure what that number is until later)

its a 96mm JE piston.. does anyone know what cc that would be??

Well, I run a 94.5 mm Wiseco and thats a 440 kit,so I assume it might be a 460 kit. But thats just a guess.
