It's quite a difference in power, definately worth the money and it's not that expensive at all if you do it yourself.

JE or Ross is a good piston to go with, you can run up to 11:1 on premium gas (some like to argue about that) but you will see more power from a higher compression piston running high-octane gas.

Definately upgrade to an FCR39 carb, that makes a huge difference also.

Where in MN are you?

thanks man, i live near brainerd. in central mn.
the 400 is just not enough to keep up with the 450s in racing

brainerd aye? I'm from St.Peter, I own a 416, love it. I did it all myself, 416je piston, 10.8 to 1 comp so i can run pump gas, 39mmfcr, port and polish, powerbomb header,HMF slip on, open airbox, and UNI. Let me know if you have any questions-darren

I absolutly love mine. its a huge difference over stock. really wakes the 400 up. with 18"s stock gearing I can pull 4th gear starts on dirt.
