pistons options for 4.6

[Graham]

Hi, all looking to put an engine together for my chim to replace the mia 4 ltr.

I've picked up a block and crank that looks serviceable,

but need to source some pistons. real steel seem to have a good deal on +20 4.6 pistons but thats still only going to give me 9.35:1

and I'd like abit more compression.

irrc you can use the 3.9 4ltr pistons that have a smaller crown volume, is that a reasonable idea and anyone have any idea what it ups the compression to.


the other option I suppose would be to use the old 3.9 tin gasket, which should be ok as im having the block and heads surfaced

I've yet to work out if I can use the gems front cover and get the alternator and pas pump to line up.

I'll either go gems/mark adams if i can get a flywheel sorted or an emerald k6, which will need the front pully modding to take a triger wheel

Might be worth having a word with Dave Davis (RND) and the guys from Devon racing. They have some new US sourced pistons that might do the job.

will do but trying to keep cost to a minimum !
