I got my W8 flanges from SPD, www.spdexhaust.com
Available for most all SB Mopar heads in mild steel or stainless, 3/8" or 1/2" thick. Very nice pieces!

Mike Gray




They might be nice but at those prices

Racer $81 for one side ($22 a piece for a left and right port $37 for the center ports)

Dealer $69.66 ($18.92 a side $31.82 center)

Jobber $56.70 ($15.40 a side $25.90 center)

These will be just as nice at almost half the price.

Do you guys want three piece? We can change the CNC program to trim them out.

There are 2 W8 flanges. Kaliher showed them to me when he made my dragster headers.

Better make sure what you have before you order....

Any other numbers on the heads? I'm pretty sure they are W9's. Maybe Ryan will see the post and know.

If it is a W9 it uses a standard W8 circle track bolt pattern. Only the Drag W8 has a larger bolt pattern... & then W9RP is it's own seperate entity.

On a W8, on one of the outer cylinders the bolt spacing will be 3.06" CL to CL if it is a circle track casting, which shares same bolt pattern with all "normal" W9's. If it is wider than that, it is a Drag head.....

Bob,

The truck series heads use the small pattern 4.750" as measured between the bolt centers on the center ports, the NHRA Pro Stock or Drag Race as SPD refers to it uses the larger pattern 4.875".

I'll take them one piece as long as they have thin strips in between.

No one for 3/8"

Besides how many people tell me they want them. I will only make a 2-3 sets more a piece. So if you are not on the list and want some please PM me your shipping address and what type you want. I will then send you a PM with my address to Ship the MO or cashiers check to. If you guys insist on paying by paypal 3% will be added to the total.
