Ron-
I was thinking of installing these on the 72 T/A I have all stock. I will bring this car to the strip with stock exhaust and see what it runs. I will then run the new tri-y to see if any difference. Will keep in touch and post the results.

I am in for a set of O ports with 2 1/2"!

Thanks soupman,
That will go good with the Dyno info that Byron (screen name bmpmdf) who is going to be in the Eng Masters contest & will have diff motor on the dyno in about a week or so. Its projected to have around 400-450Hp. So I'll test a 4-tube, a O-port Try-y & R/A manifold & post the results.

OK Ron:

I've been watching this thread since it started, and I'm convinced!

I'll be sending you an e-mail. Please count me in for a set of thermal coated round ports with the 2.5" collector.

Thanks!

[briann]

I am wondering if the 2.5" collector is the way to go since its a tri y design and having a 3" collector might not help out with flow all that much since its not a 4 tube design. Its only the 2 larger tubes entering into that area for the collector and not 4. One might be able to just run a 3" pipe off of the 2.5" collector to help with the ground clearance issuse only with the 3" collector.

[TUNNEL PORT]

Brian,
I confirmed with the header co that the 2 1/2" would more likely have more scavenging effect to it than the 3" would. Because its a smaller step up in size. So you may not have as much response at lower RPMs with the 3". I am going with the 2 1/2" myself not only for the added ground clearance but for the better response. & since I wont have both a 3" & 2 1/2" at the same time for the Dyno test, I wont be able to test that idea for a while.

Ron

[briann]

I have 3" pipe on now in anticipation for the supercharger setup, but I know its hurting me low end right now before I get to that point in project. I think the 2.5" collector size will be just fine as long as everything behind it is free flowing.

Thanks

I run a set of the original round-port HO Tri-Y headers on a '64 GTO bracket car. The car has a full 3" exhaust hooked up to the 2-1/2" collector, makes for great mid-range and pretty decent top-end power.

The engine is a fairly mild 455 with 8.6:1 compression, the '71 HO heads have some bowl work and very minor port clean-up. Runs the HC-03 cam (244/252,.550/.554" w/1.65s) and a stock Torker II/650 DP Holley.

Best ET (3550# race weight):12.055@110.29MPH

Even with the small carb and 2-1/2" collector it wants to rev to 6K, but I shift it at 5200. You can make very good power with Tri-Y headers.

These headers cost $350 OVER 10 YEARS AGO.

The new version being offered by TUNNEL PORT is a must-have for 2nd-gen bird owners and they are priced right. Don't blow what very well might be your only chance to get your hands on a great set of headers.

[briann]

Well my problem is I have ported D ports on now id like the tri-y's for, but will most likely be throwing the SD heads back on this winter so I have to decide on which version to buy as I cant quite afford D and O ports together unless he has a buy 1 get 1 free offer. LOL

[TUNNEL PORT]

Lloyd-tx,
You got mail.

Thanks b-man, I tried to get them out as affordable as possible.

Briann,
I am running a 2 for one offer. If you pay twice as much for the first set, then I'll trough in the 2nd one of same or less value for no extra charge

[Larry Navarro]

B-man is Right!!!
I paid over $350 for my set of Tri-Y's 10 yrs ago too!
Get'em now.....no whiners afterwards!

[robscar]

i wish you well on this endeavor. i do not have a vehicle that this application fits, so i will wait until (hopefully) you do a set for the early a bodies. much success to you.

[TUNNEL PORT]

robscar,
Thanks, "IF" everything goes well it will be the end of next month before I can get setup for A-bodys. I plan to do my R/A V headers around that same time.

Ron

[TUNNEL PORT]

OK its Thur. I have someone that is going to front me the amount that will be in the Pay Pal account so I can accept pay pal until Fri afternoon without having a 3-4 day wait to transfer funds to the header co. Also this allows me to accept deposit for this order of 1/2 down at time of order & 1/2 at ship date for those who cant get the full amount in on time. That will give 2 weeks for the balance incase they need another pay check.

[TUNNEL PORT]

I had to purchase a few sets my self to make up the remainder of the minimum order that was placed on Mon. So for a few of you guys, its not to late.

Come on, guys - lets support this venture and buy the extra sets from Ron. Just can't go wrong on the engineering, quality and the price!

[78 GHOST]

Sounds like a very cool project. Now to decide which ones to get for my next big project? O or D??

Ron, my email is: airdoc68@aol.com or airdoc68@earthlink.net

Honorable Matt - but remember these are F body headers!

[78 GHOST]

Lloyd, I thought you knew I had twins..

Gotta plan that next project.. 650HP all motor, with A/C and Power Brakes.. yum!

Spoke with Ron this A.M. and the money is already on the way for some 2.5" coated D-Ports.
