Timing help!!

Is this the mopar performance adjustable distributor?
Then you can do like crackedback says and taylor the curve, and without a welder.

The cam is gonna require a higher initial to get the transfer slots lined up, other wise you're already into the main jets @ idle.

BtW if it isn't adjustable like I think, you can just stretch [carefully] the advance springs, so that it will be how ever much advanced you stretch it, at idle, leaving you with the rest of the mechanical and not have it bounce around and lower on you, like happens sometimes when you just take out the heavy spring and leave the light 1 in, this method nets you around 18* @ idle and around 13-14* advance.
so like if you have 28* advance..stretch'em to use up 18*-22*[thats initial] then you'll have 6* advance from there.
