406 wiseco compression

[outofsight]

I was wondering what is the compression of a 406 wiseco piston? Also if anyone has one can they tell me how they like it?Thanks in advance!

I'd say 11:1 and run 94 octane gas if you can find it. Might be able to run 93.

If you don't mind running race gas get a 12:1. Your chances of blowing head gaskets will be alot higher with that comp.

I had one about 4 years ago and it was a 10:1. I did the piston at the same time as a White brothers All-round cam. I had a TC exhaust,no lid and a K&N, 16T countershaft sprocket. I didn't notice anything on top, but it sure had alot more torque. If I was to do it all over I would have combined this piston with a more top-end cam. It had plenty on the bottom to sacrifice to gain alittle more top.

my buddy had a 10:1 wiseco 406. i thought they made or use to make a 11:1 though too. my buddy did that along with his stage 1 hotcam and he had really nice gains from bottom to top. i would say his top end gain was as good as his down low.
