I have been having a bitch of a time getting my timing squared away on my new 383. I have had a vibration that would not go away. I thought I had a miss. I changed plugs, checked gaps, put on new wires changed springs in the distributor. I was going out of my mind. Today I checked to make sure that my timing indicator was on at TDC and it was. Finally I was at my whits end. I called the speed shop (where I bought most of the parts) and I asked " Hey guys would you look up what balancer I bought and tell me if its for a 350 or a 400 SBC. They replied a 350. I do a little math in my head and then slap my forehead really hard and yell DOH!!!!!!!! A stroker has a 400 crank not a 350. The 350 is balanced and the 400 is not. I will be swapping the correct dampener in on friday. Damn I am an idiot. I will bet this will solve the vibration and the timing issue.

 

Well I hope it works.

 

hope its fixes the problem for you...bad vibs are no fun...

 

That's some good **** right there. So many people did that **** 15-20 years ago when the 383's became so popular. Well, at least you had the ***** to admit it
People used to take 400 sb's, rob the crank and junk the block. Now the blocks are like gold. I have 2 on standby.

 

glad ya caught it before you had serious probs. that ought to run like a scalded dog!

 

Dang Dock!! i knew it had a slight vib to it when Acel.. but never thought bout that.. my brothers truck did the same thing.. and his Harmonic Balancer was shot.. you could hear it knocking.. but atleast you got it now..

Is your timing and vaccum problems sovled or gettin better???

 

the dampener is a different size so my timing numbers were off. That was the cause of the timing issues ( i hope) the vac problems were a leak around the carb. I had to stack two gaskets to get that fixed. I also found a nick in one of the plug wires (the hard way hurt like hell). I ordered more wires today.

 

You will have to get a new timing tab as well if you haven't thought of that already.

 

That is the problem I have a 400 timing tab on the block and a 350 dampener

 

So it is waaaaay out of balance and waaaaay out of time. That will do it!
