I'm interested to see the results, but unfortunately I don't really know if any of that will/won't work. Good luck man.
Thanks
Troy

i think the valve train is more of an issue than the stroke.
i also think that the pn height and piston design should be uite so tall.. ie more like every other decent motor.. as opposed to the drink botle style pistons they have now..
it is a lot of work when you will still be restricted by the head and valve train, and the fact that it is 1350cc..
fwiw, my 4K went to 7000+ nearly every gearchange for a few years. never broke.
but i like your idea .. aren't 7K rods skinny?

Sure sounds like a lot of fiddling... and the 'put a 4AG in it' mob will be willing to impart their advice on you, but I'd love to see the result if you did manage to pull it off.

I dunno I never seen a 7K rod. Look at this way, the rods in a 7K are used as long stroke, I just want them to fill up some space in the motor to bring the pistons to the deck of the block and head. They may not be partically strong, is there an alternative?
Is there anything wrong with a 4K head? like restrictions.
Could I use a 5K head and shave the crap out of it to get the CR up, as there will be 5mm extra in height in the combustion chamber or leave it, could this be useful for forced induction?
