when trying to time my carborated SB 327, i am not able to turn the distributor becasue part of the distributor (ive been told the vacuum advance) hits the Manifold runners? are there distributors with smaller vacuum advance?

 

generally the vacuum advance hitting manifold means that distributor is off 1 or 2 teeth, or possibly the wires are off one terminal. typically, in proper installs, the vacuum advance points somewhere in the direction of #6, maybe #8 cylinder. if you've had to turn the distributor more and more over time, could be time to replace it. also curious, is this a coil in cap distributor, or points style, or external mount coil?

 

how do I tell the type of distributor I have, will try to post picture in next day or two.

 

this is the HEI coil in cap style, otherwise your distributor will have only the plug wires coming out of it and be smaller

 

that is it and the chrome part is what is hitting the manifold and thank you for the help

 

I think maxxman is right, it must be off by 1 or 2 teeth causing you to rotate it too much to set the timing.

 

maxxman is right, u have to restab ur distributor

 

Thank you everyone, ive come to find out i need a Non-EGR manifold like a Edelbrock #350-2101. but again thank you everyone for your help, im going to post a new question but does anyone know... i need to replace the front and rear shocks, what stroke length would i be looking for, eventually want a lower then stock ride? stroke length 6 inchs 7in 8in 9in 10in ??? was formally a lowride so has like 12 inch shocks in front

 

t.d.c needs to be obtained first
