Nice jinx when you told me this before you put it up on here it sounds like how my day is going! So what are you going yo replace it with?

 

Are you talking about out-of-round? If that's the case there is really no fix but to bore it out. Did he tell you how much he's boring out the cylinders .010, .020, .030? if you're going aftermarket pistons, some of the selections are only in .030. Not sure if anybody customizes sizes or not.

 

Boring is 200. He said he usually goes .030 but it would probably fix it at .020. I have a question. Would .030 over make it a 408 then? The boring stuff confuses me.

He gave me some possible part prices but they are off the top of his head.

 

You need to start working some OVERTIME!!! I love overtime!! I work all of the holidays I can and have event talked a few ppl out of them so they gave me the shift! 8 hrs of overtime at 17 look great.

 

No, a 408 a 4" stroke with stock sized pistons. The current stroke length is like 3.58 inches. the bottom od hte block typically has to be clearanced to allow the rods their full range of travel with the extra stroke length.

The common term "stroking it .030 over" implies that if you are increasing the crank stroke to 4 inches to "stroke the the engine" to increase the cubic inches to 408, you are going to need new forged pistons to handle the power and the block will be usually be reconditioned and bored out .030 inches. Most good stroker kits are matched and balanced cranks and rods, with pistons that are .030 oversized. .030" is a generally accepted bore to get out all but the worst disasters a cylinder typically sees.

As a little bonus, boring .030 over usually nets 5 cubic inches, so you could technically claim you're driving a 365.

 

Well I'm keeping the stock crank. He said its fine. I guess my cam should be fine then. I'm probably gonna call and see what comp says anyway. I wish I could have found a deal like you did.

 

Are you speaking of my heads?

My understanding on the heads is that Bob at Clearwater Cylinder Heads actually does that deal from time to time. Just keep your eyes glued to Ebay, lol.

 

just want to add that the stock stroke on a 318 is only like 3.31" IIRC. That's why the 318 goes all the way to 390 cubic inches when stroked, while the 360 only gains 48 cubes.

the 318 pistons and cylinders aren't as wide as the 360's so they don't both stroke out to 408.

 

I already bought a set of the 1.92 heads.

 

And I have a 360 so the 318 stuff means nothing to me lol
