1st track testing of the alum 350 head on this forum

if you want more initial timing without adding extra timing then add a mr gasket bushing to restrict the mechanical advance.

 

Anyone know if a larger than the black, 18 degree bushing, will fit in an MSD billet dist?

 

I do not know if there is a larger bushing for the MSD than the black. thinking about bumping up the initial? then holding back the total. It would make the engine respond quicker out of the hole.

 

^^ I've used brass hobby tubing over delco pins to do exactly that.

 

TA dist. has 20 deg. of advance, initial of 16 deg, total 36 all in at 2600 rpm. I have been playing with the timing for a long time and this engine likes 16 deg. initial the best.

Have not watched to see what the drop is.

 

Larry, does your start retard retard timing when shutting off to prevent run-on?
My cam likes beacoup initial but I have to leave it in gear to kill it cleanly.

 

Does that let your eng conk out cleanly idling in Park ?
My cam likes full timing at idle.
But my idle in park is 1,100.
In gear it's 850.

 

They do make these, 10 & 14 degree bushings. If you want to run more initial timing

That one with the flats probably lets it fit the MSD bushing slot.
Good find....

 

that is a good find might need this myself in the not too distant future.
