Big Block 4X4 Headers
« on: May 19, 2022, 05:22:50 PM »
So, I'm dropping a 572 AFR head BBC in my 86 4X4 shorty and having a real hard time finding headers, has anyone gotten into this project and have any suggestions?

I had Doug Thorley Tri-Y headers in my 1991 V3500 with the 454. They fit just fine. I believe they were THY-304Y-C.

Thanks Eric but Doug's aren't an option at the moment first off not available, second they are backlogged and not taking custom orders and third they are only 1-3/4" much to restrictive for a 572 I have to get in the 2" range this sucks !
