Setting crank to cam timing on 351

Hi All, I need some help. I broke the timing chain on my 351 clevo, when I replaced it i thort that the simple thing to get the timing right was to put the crank keyway at the top and to put the little marker on the cam cog strait down. It seems to have reasonable compresion but will not start it just constantly back fires have i stuffed up the timeing if so how am I ment to set it.

Thanks Heaps

Thats right, crank key up and cam dot down, pointing strait at keyway.
Are you sure you didnt bend any valves when the timing chain broke?
Recheck your distributor timing too. Remember the rotor buttom turns anti-clockwise, and set the timing on the COMPRESSION stroke on cylinder number 1.
Good luck.

pull #1 plug bump the engine over till compression pushes your finger out recheck distributor if it does start i am afraid you hurt some valves. you can do a leak down which would intail pullin rocker arms, if your lucky you only bent pushrod like i did, good luck.

my need is speed
