I think they are a very good head for the price. Better than Edelbrocks in my opinion. They were on my 394 in my 3500 lb Dakota. Went 10.80 at 121mph. 394 cu 3.79 stroke 4.070 bore 11.4 comp Eagle H beam rods JE flat top pistons Lunati .581 flat tappet cam unported 171cc Promaxx heads Comp cam roller rockers M1 intake 1000 cfm Holley carb These Promaxx heads dont have a lot of runs or street time on them which are for sale now. Have not posted them anywhere yet. I'm swapping them out for the new Trick Flow 190's. Let me know if you're interested in them.
did you put some trick flow heads on and pickup any power over the promaxx??
Pretty sure a guy over on A body’s only bought his ProMax heads. Still waiting to hear results
That was me. I'm everywhere. I bought his old heads but I won't have them mounted until next spring. They are used but look really good. I'll take them apart this winter for inspection and to familiarize myself with them. I don't know where @1965fish is with his TF project.
