304 vs sIII piston std
Does anyone have a standard sizes piston for a 304 roller block when to put the Pistons back in after knocking off glazing and found that some dropped something on one and cracked a skirt
Re: 304 vs sIII piston std
There are different sized “stock” pistons. When I bought my block and pistons from Holden they had A B or C stamped on them to designate size. Where are you located ? Duggan balancing might be able to help you, if you get really stuck I’ve got 8 here I’d have to check condition though
Re: 304 vs sIII piston std
I'm in Perth I don't mind paying for postage. There wasn't anything stamped on the Pistons in regards to size but there is a b and c stamped on the block corresponding to bores I measured them all up though and we're all the same as far as I could tell. Piston measures at 101.59mm I think it was widest point

Don't have an issue with them being used just so long as they're in ok condition

Grab the ones off 202, mine are still on the rods

Pistons are cheap, I wouldn't even bother.
I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.
Re: 304 vs sIII piston std
I would get new ones but I've just stuck the cleaned up old ones back in. bores just needed a scuff up with the hone and they're all good went to put no 8 back in and it wouldn't even start in the bore so had a look at it and looks like some knocked it or dropped it and the conrod has hit the inside of the skirt cracked it and pushed it outward so bottom end is basically reassembled bar one piston and you can't buy new standard Pistons anymore I've called Holden and acl/nason and they don't even have stock or make them at all
Re: 304 vs sIII piston std
Thanks to Holden202t sorted out a couple of Pistons for me now just to scrap all the crap off and measure up hopefully should be ok then on to playing with the heads
Thanks all
