I just had to rebuild my 450. I bought a brand new jug, piston, valve head and the whole 9. got it all back together and I dont have any compression. I got my timing marks lined up according to my manual but still nothing. Any ideas?

Make sure you put your cams in correctly on TDC.

That was my next suggestion.......just check everything with a fine tooth comb, it will become apparent. Let us know what you find.
