I’m looking to put high flow exhaust manifolds in my 1971 Roadrunner with a 383. Does anyone have suggestions?
Thanks

You could probably track down a set of the HP '68-'69 manifolds on here and restore them or order a set of the reproductions from Year One (around $400+sh).
 
Ebay usually has some reasonable and some over priced. Bluestar performance usually carries a pretty good selection, some are pricey..not hard to spend 500 for a good set. Occasionally a odd pair can be had for 250-300...takes some looking. Pass. side seems to be harder to find and not unusual for that side to be cracked. Year ones aren't a bad deal..just depends on what you want on your car.

I thought a 71 Road Runner with 383 would already have the HP manifolds from the factory This one had them removed?
 
I thought the '70 & '71 HP motors also had the good manifolds. Correct???
