Thread: Need timing help, cam swap

Tweet

Ok , ive got a 34 chevy coupe with a 81 chevy 350 motor in it. Im did a cam swap today and timing chain. when i pulled the dist i set the timing mark at 0 and was TDC on number one, i checked and the piston was at the top of the cylinder. did the cam swap, changed out the new timing chain and gears and put the cam at 6 and the crank at 12, aligned the timing marks and, will not start, it will turn over but will not catch, it also seems to spit gas out of th carb. I put a rag in the 1 cylinder and turned it over till the rag blew out and then checked and the piston is at the bottom of the cylinder..why? also when it blows it out its not on the timing mark but on a mark that is scratched into the balancer..is this 180 degrees out? I tried to re stab distributor and start wiring where the rotor is pointing and continue around with same results... can anyone help?

distributor is 180 degrees out

Can i get a step by step to correct? Dont wanna
Wash new cam,

Bring #1 Cylinder to TDC on the compression stroke (just after intake valve closes), Put the distributor in with the rotor pointing to #1 spark plug wire.

thanks guys, got it, 180 out.

Good to hear you have it running now, I would imagine most everyone on here has dropped one in backwards a time or two (or ten) in their life!!!!!!

Not everyone knows that cam at 6 oclock and crank at 12 oclock is the #6 at TDC.
I have fallen in that trap more than I care to tell.

I put one in out of phase every so often just to stay in practice. Those flames shooting out of the carb is a dead giveaway though.
