here is a sneak preview of the try Y headers I am building for the frame off restoration ,, this car had a set of belanger brothers headers ,,so the owner wanted a set made ,, the top sections are mocked up the bottom sections will be done coming up this weekend,started with 3/8 stainless flanges,1 3/4 16 ga stainless for the primarys,, merged into (2) 2-1 collectors to a 2" v band clamps,,from there will be (2) 2" 2-1 collectors with a final 3" v band clamp,, more to come next week

Nice clean setup.
Looks like you used very few individual pieces and I like the connectors.

Nice quality work! Very clean

Interesting, headers with plug clearance!!
Envy your abilities, keep us posted

gmonde

thanks guys,,yes plug clearance was one of the biggies ,, also oil filter and starter access ,stay tuned

gmonde

up dated with the bottom half of the collector ,start up in the next few weeks

Are there performance advantages to the tri-Y setup over normal full length headers?

GCD1962

seems like a lot of time and effort and little gain over what could be bought of the shelf

I had Tri-Y headers on my '65 Mustang K code, great pipes.

Have you considered pairing cylinders 1-5, and 3-7 to avoid the successive firing sequence of 5 & 7?

gmonde

the problem with off the shelf is they never fit the way you want them to,, if your looking at the block huger headers you might as well use stock manifolds the are horrible for flow,, I have proof,, , plus they are a heat sink ,, yes a little extra work but well worth it ,, each engine likes different configurations,, there are some nhra stock eliminator guys that I built a few sets for swear by them for that little extra gain in horse power,, plus using this in the corvette chassis helps for pipe routing to the stock location,, also I will be doing a stainless exhaust as well ,, the stock stuff is restrictive as hell ,,stay tuned

gmonde

yes I have and was my original plan but it would turn into a lot of extra bends and not enough room plus the more bends you add it will build restriction ,if this was a open race header I would have gone the extra but since it will have exhaust ,you might gain some

tri-y headers were the exhaust of choice on the mopar wedge engines.

When you create something like this there's a certain satisfaction that some people will not understand...again, beautiful work!

Very nice work.

I had a set of headers built for my 69 by the guy, Calvin Elston, that brought the tri y design to NASCAR. He says any car revving less than 8000 rpm's would benefit from tri y's. Also says the most important part of the header is first 12 inches and includes port match. Says most exhaust ports are too large. Nice job on those headers. You are doing the right thing there for your cars performance.

Bet they would fit a C2/C3 frame as well. Lots of clearance and close to the block so you don't hit the steering column too.

gmonde

thanks guys ,, I ordered all the stainless tubing and mufflers 2 1/2 ,, stay tuned

I have Doug Thorley headers on my '64 and they are very nice. While mine are not the Thorley "Tri-Y", those aren't the pipes that Doug joins in his designs. And he's been doing "tri-Ys" for a long time.
