440 bore size

[brian6pac]

I always do the cyls first take out only what is needed and of the bore is not normal, say .0225 over then I order pistons from Ross for that size bore and they are usually spot on. Why would you go to .030, if the walls get scuffed or something happens not to bad than go .030 or .040, were as if you went .030 to start with going to .040 might not fix it than you are going .050 or .060.

I looked up that P/N on Summit, and it shows that cam with 494/513 lift as being a hydraulic flat tappet cam. Is that the cam you are using? I'm trying out a solid roller cam. Let us know how well yours works!

It's deffinatly the roller cam probably gave wrong part# as I had a list here of what I was debating to use,I'll check # n post correct one.that a deffinate yes when I get it all done n said.

For what it's worth...a machine shop won't make any cuts on your cylinders, until they have your pistons in their hands. If you already have pistons, machine shop should ask for them.

If your machine shop wont do what you ask it's time to find a new one.
If you are getting custom pistons you need the bores done first.
