Is anyone running 1 7/8 tti headers on a small block? The unknown brand 1 5/8 headers that I took off when I started this project were awfully tight. Just wondering how they fit. I now have trickflow heads, not sure if that will effect things

I see you and many others run a x pipe. What is the main purpose of it?

Both H and X pipes, are used to equalize the exhaust pulsation between the cylinder banks. This usually tones down the lumpiness at idle to some degree. The equalization of pressure between the banks helps with cylinder scavenging on the port and can help contribute to better cylinder filling. Generally speaking an H pipe provides better low end torque, while X provides better mid range and top end. H pipe gives classic muscle sound while X pipe is a little raspier tuned sound. I run a 3" TTI X pipe on my W2 head 69 Swingers 408.I see you and many others run a x pipe. What is the main purpose of it?
Oh comp ratio is 9.95It is a 426 small block. The Dyno say 602 hp@5800 and 616tq@4500 with 1 7/8 Dyno headers. Cam is 408/258dur intake and 408/264 exh. @.050. 1.6 rockers

110What is the LSA on your cam? Your compression is low enough you could probably use a 2 inch tube.
No power steering. Engine is not in the car as of yetPWdart, are you running power steering, and if so, any pics of the drivers side from the top?
Thanks!
My bad, Just Send it had posted the pictures.No power steering. Engine is not in the car as of yet
As said above…. The H and X pipe help balance the pulses of the exhaust. In tests I have seen, the H & X are super close together as far as power is concerned with nether favoring ether side of the curve more than the other one to make a big or little difference on the street or track. They’re always within a few ft. lbs. or HP of each other.I see you and many others run a x pipe. What is the main purpose of it?

I put a set of 1 7/8 hooker headers on my 69 dart 340 with x heads back in 1971 and still have them on they are tight on the drive side but they fitIs anyone running 1 7/8 tti headers on a small block?

Do you have any pictures from the top? Not sure if you’re running power steering, but wondering about clearance.I have their 1-7/8" full length headers and Trick Flow heads in my 72' Scamp. Fitment was tight but everything went together great. Helps to install them from underneath using a lift

I am out of town but I will be back next week and send a picture but the car is automatic no power brakes or steeringDo you have any pictures from the top? Not sure if you’re running power steering, but wondering about clearance.
I have a similar displacement small block engine that was dynoed with both 1-7/8" and 1-5/8" TTi headers, because I already owned a 1-5/8" set, so I wanted to decide whether to spend the money on a set of 1-7/8". The difference was around 15 HP, with an Indy intake and Holley 1050.It is a 426 small block. The Dyno say 602 hp@5800 and 616tq@4500 with 1 7/8 Dyno headers.
