Bob recieved a Z-400 top end the other day for a port and polish. I was wondering if it belonged to a forum member on this site? Jerry said he was able to do a lot with the Z-400 head. Just curios, i know the owner lives in lousiana. I also head 2 more were on the way. Looks like there are going to be a few bad *** Z's out there. It will be interesting to see how they do when built.

 

Hey Mark, keep us updated on the results if you could. I'd really like to know what #'s Bob can get out of 'em. Fill us in on the particulars if you know what's being done and any prices if you could. They should haul A$$ when Bobs done with them. PM the results if you like.........

ltz- The first head that came in was from a dealership. I do not know what all they (dealership) is doing to the rest of the motor. (cams, pistons) but i will follow it up as best i can. Jerry (craycraft) said it looked like a lot could be done and the intake were large enough to.....

 

In the process of purchasing a new 400 what kinda mods can you do to it?
any recommendations for my sons blaster. just rejetted it and installed a new exhaust.

 

Thanks Mark. If you get any #'s let us know............


ferrett35, open up the airbox, get a good airfilter, put a new pipe on, re-jet and enjoy!!! If you want more- cams, port/polish, bigger bore, gearing. It all depends on how much you want and how much $$$$$$ you have............

 

LTZ- Jerry at craycraft spent most of the day porting and polish the Z head today. He said that based on what he has done and what he does with raptor heads this (Z400) should realy run well. He said it had good numbers based on the valve size, runner lenght etc compared to the raptor. This head is shipping out this week back to the dealership. Hopefully will have some reports in about 2 weeks from the customer. Hopefullly we can find a local with a Z so we can do a build and see what the Z will do. It has a good base to it.

 

when I pick up mine from the dealer, I'll run it over to you, and let have at it.
