TRI-Y, CYL PAIRS ETC.

COLD

Well-known member
My header flanges are ready, ports are done for 2" pipe and with the $4.00 a foot I was quoted for 2" (found some for $3.00/foot) I thought I might do TRI-Y. I did a drawing of the engine layout with cylinder numbers and firing order and running mates labeled. Do I want to just pair them with regard to cylinder firings furthest apart or what?

1 (1) 2 (8
3 (4) 4 (3)

5 (6) 6 (5)

7 (7) 8 (2)

Cylinder numbers left of brackets, firing order (like #8 is the second one firing) in brackets

Running mates

So like 2 and 4 and 6 and 8 on one side and 1 and 5 and 3 and 7 on the other? :?
