You'll find with carb testing that once you tune one that's dead nuts on the money for your set-up, there is NOTHING waiting for you on the time slip messing around with anything else, it would defy the laws of physics if it did..........Carburetors are metering devices, wouldn't matter if you carved one out of a block of wood, if it provided adequate cfm, seamless transition and A/F spot on across the load speed range nothing else is going to improve anything.
Same thing with distributors and bug zapping ignition systems, very little if anything waiting for you there either, provided every one tested was dialed in the same and it good working order.
The torque converter is a MAJOR player in what you are doing, LOTS of variables in that equation, flash stall, load stall, torque multiplication, efficiency once past the stall speed, etc. Certainly looking forward to seeing if you can find anything there.
18mpg's is getting it done for an HP950. I suspect someones been into the metering blocks and airbleeds in the main casting or it's a winning lottery ticket!
I've been off the Forum for a while, what is the "new" engine combo?.........
