timing adjustments For 1500 inline 6

[urbanp]

I read the Timing post by Clamscanino about adjusting the timing for inline 6 up to 88.

The only question I have about this is how to determine if my 1976 1500 is a direct charge" crossflow which requires 21 deg max advance or a plain crossflow which requires 34 deg max advance.

anyone familliar with this?

"The "direct charge" motors appeared in 1970 and most have a sticker advertising such. All of them use the same 2.75 bore and piston with a funny "eyebrow" on top of it. The 402 and all the larger (than 50hp) inline 3's,4's,and 6's were direct charge through the 70's and 80's."

The above quote was taken from Clams' thread, page 2.
I would say you have a "direct charge".

Hope this helps.

urbanP, I have a '77 1500 Merc. It is identical to the '76, and is a direct charge model.

Yes all the 1500's, 1350's, 1400's, and 1150's are direct charge.

21 degrees max advance. Is what you want to set it at.
