yes, the holden and chev small ends on the conrod are both 0.927".
you can use a 327 chev piston with a 1.678" pin height. that is the closest you will get to the 1.69" pin height of the 308.
are you looking at forged or cast?

Use Holden pistons. Chev pistons will give you the wrong quench and lead to pinging and loss of potential hp.

unless your putting a blower on use cast pistons. they are lighter and will do the same thing.
ACL rebuild kits are around $600, and just ACL duralites are around $300.
I was looking into forged 327 slugs for my turbo project because ACL forgies are $14

where did you find chev pistons $300 cheaper than cast holden pistons? holden pistons must have been bloody expensive.

no a domed piston will not rectify the quench problem, its the flat part of the piston crown that determines the quench.
The head being machined wont make a difference either. do it anyway to gain back some compression. the only way to fix the problem i

if you are getting adjustable roller rockers anyway, go for a solid cam. the crane 304 is one of the biggest hydraulic cams you can get. why not get the extra benefit. clearly you aren't fussed about fuel usage with a cam like the 304.
Or be like every o

why VR block? the VT and VSIII are the only blocks that came from factory with roller cams.
If you want a roller cam you have two options:
1) buy retro fit roller lifters from crane ($750 approx)
2) have you lifter bores sleeved and centred to turn the

VR VS and VT were all factory cast for a stroker crank. this maybe what you are thinking of.
