2cnd I have checked out you and your dads beautiful cars on numerous occasions,they are breath taking.
You guys are always in the motorhome so I really haven’t talked to y’all much

My 2cents on your original question, have you tried merge collectors?
I’ve always heard keep making the choke point smaller and smaller until it falls off then go back to the merge collector that made the most power.


I’m in that horsepower range but our motors are way different considering I run a 18 degree big chief head.
But for what it’s worth I have a 2 3/8 primary tube and a 5” merge collector that chokes down to 4”.
Feel free to knock on the door any time. I may have you mixed up but did I talk to yall at bowling green a couple years ago? I’ve been looking at collectors but trying to gather more data before buying. I believe I’m going to build another set with smaller tubes & merge collectors . I got a quote from Burns yesterday but they forgot to title the email sit down before viewing.
