timing small block chevy

I just put a chevy 283 in my cj-5.I also put a edelbrok four barrel intake on it.I found t.d.c. adjusted distributor to point at #1 blah,blah blah.Anyway it doesn't run.It backfired couple times scared the sh&t out my dog.People tell me it could be 180 off or an intake leak or a million other things.Does anyone know of a real good website for timing this engine? thanks

Re: timing small block chevy

It's almost certain that you got it 180 out. When you're turning it around to TDC, put a finger over #1 plug hole. If you don't feel a good stout push of air, take it around one more time.

Re: timing small block chevy

Just because I don't know what "blah blah blah" means [img]images/graemlins/confused.gif[/img] I give the "fat" to Jim's "skinny" here.

Remove number one plug. Either get someone else to crank it while you hold you thumb over the plug hole or stuff something like a cork in it. When it gets to the compression stroke ..rotate the engine by hand to TDC.

If distributor is out ..drop it in. If it's in ...where ever the rotor is pointing is # 1 ....follow firing order around the dirstributor.

If you need a certain distributor orientation ...turn it that way before you start placing plug wires.

If you need a certain post to be # 1 ...lift distributor and turn rotor a little and lower back into the engine ...repeat as needed until rotor is pointing to that post.

Start engine ..set timing.

You may be 180 out .......but if you did what I just described above ...it would be unlikely.
