Piston choice for 598

G'day guys,
Time for an engine rebuild and want to step up a bit from the 572ci combo I have at the moment to 598ci.

A460 block currently 4.500
Scat forged crank
6.8 Eagle rods
Blue Thunder B heads

I've had a bit of a look in Diamonds catalogue and there doesn't appear to be a spec piston to suit, would appreciate any suggestions on where to look for piston choice or is a custom piston the most appropriate choice?

Thanks.

Isn’t the Blue Thunder B a standard CJ type valve layout piston?
What about Icon, Mahle, JE?

Racetec.

Looks like the Mahle Book Slugs stop at 4.5/6.7".

Might Give Them a Shout and see if The can Cut you a set for the 598.

Buy a custom set of pistons and be done with it...

^ What Randy Said.

I saw These for C-Heads Floating around, for what seems like Over a Year.

I Don't Know if It is a Good Idea to Add Valve Notch's or if They are Workable for Your Deal.

I Bet You Could Get Them for much Less Then Asking or Custom Pistons Though?

Just Passing It on as a Possible Option.

As Always: Not Mine and Buy at Your Own Risk.

In the 1970's, custom pistons cost around $850.00 ... NOW custom pistons can be had for about $950.00; and they are much better quality today.

Nothing in this industry has increased in price so little in over those 50 years.

were do you get custom pistons for that price? i called kasse he quoted me 1830 for custom pistons ? and $350 for rings quote="rmcomprandy"]In the 1970's, custom pistons cost around $850.00 ... NOW custom pistons can be had for about $950.00; and they are much better quality today.

Call CP and get changes made to a shelf, (catalog), piston to make them customized.

Other piston companies will do the same thing.
