I may be interested in the try y headers, But I had talked myself out of fancy coated headers because I know eventually they will rust and look undesirable. Let me ask how much are you asking and why are you selling them ?

Thank you PRH . Seems like so many people on here have reported that they work.

Considering these to swap a 383 into my 69 valiant. Are they better or worse than the originals ? I am open for suggestions on why I should or shouldn’t use these. Motor will probably be 400 horsepower. I’m not buying tti headers. Thanks

Thanks guys . Andy , that is my worry ... not knowing quality of the build. All of you guys have great valid points. Thank you

I’m in cheboygan , zip 49721. Not in a big hurry. Hopefully in the next 3-4 weeks. I have a cast crank I can use if I have to, Was hoping to rebuild with forged so I don’t have to weight flywheel.

wow thanks for the info, 300 grams is quite a bit ? I bet a lot of people end up in my same situation ? or maybe most people keep stock rods and only change pistons, in that case maybe they don't get the vibration. Thanks again for the info.

Replicaracer43 is correct , it was just thrown together with the parts I listed. I obviously don't have much experience building engines like this. I was hoping to hear from somebody who has built something similar and hear about the results they have. Thanks guys ! This forum is a bunch of...

Thanks for the input. Yes the weight is on balancer. When I took the cast crank to a local machine shop the guy told me I was crazy for wanting to balance that crank and it wasn't worth it. I assumed (I shouldn't have) the pistons and Rods would be closer than than stock and wouldn't have to...

so , car has vibration between 2,400 rpm and 3,000 rpm in park, neutral and driving. It seems to rattle the steering wheel and dash the worst. its a 1977 360 bored 40 over with Kb107 pistons and scat I beam rods. cranks has been turned 10 under on mains and 20 under on rods. edelbrock rpm heads...

wow nice car, keep us posted. welcome .

old man ray, I am jealous !!!!

shots can help, but they are not a long term solution. my first one lasted 2 weeks, doc said I needed another one, the second shot didn't do anything. Before surgery, please try physical therapy, it really can help.
