505 Build

Yep, headers would be cheaper. I had hoped they were an aftermarket option. I think I’m settled on HP manifolds but a better flowing cast iron exhaust option was intriguing.

Only way to be informative waz to tell ah story bajaoaquin. Both the J+K's and Tri-Y's are thingz of beauty Pal. You'll recognize both instantly if and when you ever see either set. The J+K's are 4 separate down sweeps into a 3" 4 bolt flange collector on each side. The Tri-Y's are ah bag of snakez that sweep up and then down after making 3 Tri-Y patternz on each side and I think the same 3" collector with a 4 bolt flange(hard tah see from the top) Jer

Paul at Gray's Performance ran the engine on the dyno on Friday. I don't have the dyno sheet, but it made 531 hp and 623 ftlb. Sweet torque. Small cam, but good for moving my 72 Fury. You can see the dyno run on facebook
