Thanks Bobby the bog has been sorted. Too much vacuum advance. Your post make a lot of sense to me.the older style fast before this new stuff requires a bit of work and tuning.
the self tuner....work pretty good. if your happy with a carb you will be happy with those. i have installed both, though not recently in rangers.
you may consider putting it on the dyno to help diagnose the bog with the 4bbl. may need a bit of a timing adjustment or maybe move the cam around a little with a rollmaster if you dont have one installed already. the 347 make quite a bit of torque compared to a reg 302 down low, but seriously a stroker 351 is ideal for your use. i run heavily loaded as well in the general and a reg mild build 302 with efi was always working pretty hard. the 351 is a different beast all around for work.
of course your trans and split shifting are harder to match with a carb as well. those old creeper transmissions were made for low rpm nutless no power pussy engines. if you like a 435 or t18/19 trans in stock form on the street...your engine is a bitch. at least with overdrive splitting you can actually use your engine.
so the efi might not impress you as much. i know i would prefer the efi regardless. you dont get as crazy as some of us so the 4 bbl is quite usable and hard to justify the cost of the efi upgrade. but it will be a upgrade. i can not see any performance lost at all....simply maintained or gained in every area.
While on the subject of the 347, I will finish off its build. My goal was to reach 400hp and around 400 ft/lbs. Power and torque needed to turn those 35`s I planned to install.
Here is the tech list of the 347`s vitals.
1. AFR 142 72cc heads.
2. Comp roller cam
3. Crane roller rockers
4. Weiand Street Warrior intake
5. Holley 670 Truck Avenger
6. Mallory dissy
7. Edelbrock high flow water pump.
8. Professional Products stainless bolt kid.
Thanks again my current cam start to pull hard from 4000rpm.i would consider the truck cam after reviewing this.
nice!!!
