Bump.

 

At least .040 over...and likely much more. I dont know the exact limit, but i could ask Darton for you. We can make the Arias Extreme duty in any bore size you desire.

 

Any disadvantages to going to a larger bore?

 

Nope, unless you dislike more power and trq across the board.

At some point, there may be some modification needed to the headgasket, but I havent measured it to detemine what that is.

Boring doesnt result in huge displacement gains (or power gains)....that is where a stroker kit really comes in. You just need to check on the thickness of the sleeve, and the sleeve manufacturer will have a recommending overbore limit for each application. If it was my motor, I would probably go .040 and leave it at that. THat would make your 3.5L about a 3.6L.

 

Ahh, ok.

I was thinking about .040 as well.

 

Brandon, the 650whp goal seems a bit lofty. Are you planning on headwork? I know you said you were getting a longblock, so I assume you are doing heads, springs and retainers and possibly oversized valves. So far, no one outside a race team has put down an uncorrected number over 620 on pump gas. I would say shoot for 450 and maybe 600, still pushing it.

The SGP pistons are CP pistons, it is just modified to their specs. Sounds like you will be building a beast. Best of luck.

 

Yes, not at first though. After the block is built up, later on i'll get some OEM heads for them to build. Tomei 268 cams and Ferrea valve kit.

 

So the 650whp goal is later on down the road, or do you think you can get there w/o headwork?

 

Well, i'm going to try to get as close as possible without headwork (safely).
