Houser Frame Question

[miles Machine]

What would be involved if i bought a 02 Houser yz426 frame to make a crf 450 engine fit, maybe just mount change but im not real sure. any help would be awsome

Headstay would need to be cut off, and replaced by the CRF style headstay plate, bottom mount would need to be rotated, and front engine mounts would need to be remade.

dont hack up a true yz houser frame.
the 426 is a great engine at the least, and if you really want a 450 then either bore out the 426 to a 444 or get an yz450.
the diffrence between a 426 and yz450 is not much in mounts.

BTW I had a stock 426 engine and was competitive In the A class VS tons of built 450's
