Cambridge Motorsport carries 60-over cast Hepolite pistons. That's as big as
I've seen without going to forged. I have a set of +2mm forged pistons on
backorder with them, should ship in 3 weeks. ISTR the price was quite similar.
That's 76.7mm, should be good for 2632cc by my calculation.
Some forged pistons require looser piston/bore clearance due to greater
expansion when hot, but CMS recommends just 3 thou, measured 1" up from the
skirt, for the pistons I ordered.
Good Luck, Tom
