i did one for my buddy and we used a 450 cylinder and head along with a cam and high compression piston. he bought the head and cylinder on ebay and dropped them off at the machine shop. save yourself a lot of money and increase your displacment too. he turns 27 9.5 front and 27 12 rear outlaws.

You can see in my sig that I got the BBK on my 450.  It does add power, but, if you sink it, its makes it a lot more susceptible to 'egging' the jug than before.  A thinner wall, more heat...  I think I would have been better off with just jetting the carb right, a good exhaust, and a cam.  Mine got sunk about 8 times before the BBK was put in, and several times afterwards.  Seems like it held up better before.

We have one we have sold for years. It is our J&E dome top 475 CC  kit. The piston size is 93.479mm.
The kit has everything you need, the high compression piston, rings, wrist pin, circlips, head/base gaskets and sleeve. It sells for $302.50. We also have the 20 over 90.5mm & 40 over 91.1mm  high compression pistons available.

Dan isn't the .20 an .40 overbore for a foreman 450?  Awhile back there was acouple guys with foreman 400's that kept having problems witht he 475 kit.  They then used a 450 cylinder and had no more problems.  I don't know what the deal was with this nor if there was a problem with this.

slowredcoupe -> RE: foreman 400 (9/7/2008 9:43:26 AM)

can i just get a 450 sleeve and piston for the 400 lmk thanks



Jake450s -> RE: foreman 400 (9/7/2008 10:22:29 AM)

to do that, you'd need a 450 sleeve, a 450 cylinder (or machine yours, just like a BBK, a 450 piston, and a 450 gasket set.  That'd get you a 433cc engine with stock compression.



slowredcoupe -> RE: foreman 400 (9/7/2008 11:53:03 AM)

WOULD YOU DO THIS OR A BBK IM WOULD LIKE JUST USE MY HEAD FOR THE 450 STUFF WHICH IS BETTER
