hi guys one of you ultra wise people here maybe able to answer a quick question for me

 

i have just piked up a standard 5k bottom end ( flat pistons) with I'm told a unknow race cam with stripped 5k hydo liffters and diff push rods dato ones i think and the head is I'm told a 4k-u item will this work .

 

ruff idea of a comp ratio will it be safe ?

lol just pull the head and do the measurements if you don't think itll be ok bro.

 

use the usual method to work out the swept volume of the pistons and a syringe to work out the CCs of the combustion chamber.... i roughly did it one night before i assembled it and it *should* be ok with a decent tune and good pump fuel...
