Won't Fire - Need Help!

Yup pop the valve cover off and start over with a piston stop. Watch your #1 cyl. for your TDC using your piston stop. Make sure both valves are closed on #1 cyl. Once you do that set it at about 10* BTDC and stab your dizzy pointing to the #1 cyl.

Thanks. Actually have a TDC Finder, but never used it... Will have to figure out how since it didn't come w/instructions...

Pull #1 plug and bring the piston up to TDC intake compression and see if the balancer lines up with zero on the mark. This will tell you if it's off or not.

What year of 340 and was the original crank, damper and front dress reused?

Thanks. Not sure of crank year. It was from my previous motor that I replaced with a stroker crank; but it's forged... Not sure on dampener and TC cover since I bought them separately...

I think you were prob right the first time,, you just needed more timing,, and you may have a wire crossed..

Will double check firingi order again, next -TDC/Timing mark, and if all that checks out, will rotate the distributor 180...

Check the firing order. Only takes a minute, doesn't cost anything, and won't wear out the starter. It will do no good to have the rotor pointing at the correct wire if the other end of the wires aren't where they belong. Oh, and make sure you advanced it ten or fourteen degrees and didn't retard it by those degrees.

Agreed! Will definitely check and re-check these items.

Thanks All for the suggestions! Much appreciated!!
