Hi everyone, i'm looking into buying some of these for a turbo build i'm planning.
Found these on ebay from the US at a great price, but then realised they're for a blacktop, i've emailed the company and the guy says he's 99% sure they'll work in a silvertop as the rod length differences are made up by the piston pin location, but asked me to do some more research to double check this. Any help would be greatly appreciated, as i'd love to bag these at this price
Cheers

yes they'll work.
the difference between the silvertop and blacktop is in rod and piston height.
the silvertop had shorter pistons but longer pistons.
the blacktop had longer rods but shorter pistons.
overall they work out the same length and both use the same cranks and bore etc.
it has been known to use silvertop rods and blacktop pistons to lower compression for tight ass builds![Wink](https://passionford.com/forum/images/smilies/icon_wink.gif)
as for price, that's not bad i used a company called race engineering who sorted out custom sized pistons and eagle rods, arp rod bolts as standard in rods, and main and big end shells for Ł650 delivered (Ł140 customs on top may i add).
remember customs, lucky if they don't sting you, plus the handling charge from courier.
