question, has anyone used a 440 ims kit or a high compresion 11.1 standard bore kit and if so any commits are welcome like power reliable overboar sizes which choise is best and any other mods like where to get front shocks new at good price tx!

 

Go with the 88mm (426) 11:1 compression piston. It's only 8% smaller than the 440 (almost unnoticable)- and you won't have to sleeve your engine- So you save CASH- and allow yourself more room to upgrade in the future.

 

tx for the advice i am going towards a 416 eng after talking to white bros teck seems that is ahappy med between the 400 and 440 tx!
