It this from the valve (subtract the exhaust port length from the 40"), or is that 40" from the header flange? I am looking for mid range torque from the 440 in the Jensen, and looking at a Tri-Y design. Pipe max lists a two step, and a three step Tri-Y? Is the first step of the three step, just a pipe step before the "Y"? I think the paring for the "Y"s are 1&5, 2&4, 3&7, 6&8? Are you talking an Interceptor? You will be running primaries below the floors for sure with 36" long primary tubes!!! I have Delta SS headers, they are like a block hugger header with a tipped out slightly longer collector. There are longer primary headers available on the UK Ebay, take a boo..? Or maybe I'm not reading this right..? lol CrAzYMoPaRGuY
