I have a 40 Coupe that has a 53 Merc bored 30 over with a Isky Max1, Joe Hunt distributor, Reds Headers, Navarro Heads and Navarro 3x2 with 97s. Trans is a new Tremec. The engine has 1976 miles and was built by a reputable builder in Austin. Here’s the question.....do you flathead gurus think this engine would be a better driver with a Holley or Edelbrock 4 bbl. and a Mallory Unilite? It runs ok, but I’ve spent a lot of time setting up the carbs(progressive linkage) and timing and I’m just not satisfied with the performance. It idles ok after syncing and setting mixtures on the carbs. I’ve set the timing using a vacuum gauge because there aren’t any degree marks on the Fluidampr crank pulley. Today I drove the car about 12 miles at 70 mph and on the way back I heard some detonation when accelerating.......came home and backed off of the timing a bit(using the vacuum gauge). I then had to reset the mixtures again because it was idling rough. I still haven’t been able to get the idle back as smooth as it was before I lowered the timing. All of this to question the 3x2 setup with the Joe Hunt distributor......while it looks really cool, I’m much more into decent performance and drivability. It seems like every time I turn around I’m adjusting the carbs and timing! What do you think? Would a 4bbl and more conventional distributor be a better setup for a driver? Surely some of you guys have experience with a flathead setup similar to mine.
