check if you can bore a 400 out to 450cc (ie not so much can the bottom end take it but is there enough meat on the barrel). px your 426 for a 400 & make a profit. put the money toward taking that barrel out to 450cc. remember that the little end was increased in 99 so don't do a deal on a 98,ok?
while your there definately go for the big valve conversion. no if's or but's. so you might as well port it as well of course.
