88mm, 32.5mm comp. height flat top pistons?

Hi all,

Well plans are afoot to knock out a bit of a stroker engine. I've pretty much finalised the piston spec as above. The low compression height is to help keep the compression to around 10.5:1 and allow plenty of valve clearance without having to machine the piston tops. I've already got an E88 head that's been shaved by 0.030" so compression isn't a problem.

Only problem is finding a piston to this spec. So far I've got a quote of £125+VAT each from a company for forged pistons. Yes that is nearly $260 :eek: The best bit is that they probably wouldn't be able to deliver for 6 months :sleepy: I'm waiting to hear back from another company but I thought I'd pop over the virtual pond and see if you guys have any recommendation/ideas. I've got no problem with importing pistons from the US (or OZ for any of our southern hemisphere cousins reading) if the price works out right.

Also while we're on the subject of pistons, what are your thoughts on cast v forged? As I said the planned compression is 10.5:1 but the engine won't be revved over 7k. However I am thinking - further down the line - of trying a low boost supercharger on there and simply dropping the compression to around 9.5:1 with a 2mm head gasket.

Cheers folks,

Rob

helloooooo, echo, echo, echo

Any thoughts peeps? I filled out the custom piston form on Top End's site but not heard anything

Cheers,
