Okay. My update.
I have been driving it. It's running rich. Finally figured out the issue. I have the wrong injectors. Somehow I have 350 injectors and not 4.3 injectors. Lol.
That's what I get for buying used 3rd hand.
So I have yet to get new injectors. Will do that in the coming weeks. Then off to dyno.
Other than that no issues. Paint still looks new even with the wheeling and driving I've done. No leaks to speak of.
Best part is when your in a situation where you need to go all you have to do is put your foot to the floor.
Oh and it runs good at an angle.

Can you program a PROM chip and modify a .bin file? If so, just change the flow rate of the injectors in the prom editor file for now. I had mine flow tested on an old rig, and just a change between .bin file 19lbs to the actual value of 18.5lbs/hr made the BLM fluctuate a whole lot less.
Its calculated in seconds/cc or something like that so you do have to break out the calculator, but its pretty easy to come up with a good number that will be a whole lot closer than what you have.

Just a small update on the motor. Have had a rich issue. Basically blows black smoke out the pipe no matter what it's doing. Pulled some data logs and sent them to AFI. The guys there said they have done 50-60 of these setups with their original stock setup but nothing with the cam I had as well as other mods. So they burned me a new chip and I installed it Monday. Hands down I have even more power than before as well as my rich issue is gone. So now I'm on to bigger and better things.
Did you ever dyno Big Gay? If you did I must have missed it. I'm hoping to have my 2F back from the machine shop in the next few weeks. Should have it running sometime in May I hope. I can't believe how much i've spent on this project, but hopefully i'll only have to do it once.

Just wanted to comment on this because AFI mentioned this. Said my voltage coming from my alt was not putting out enough volts at idle. Only until I got over 800-900 rpms did it start charging. Most likely due to my one wire system. Going to put a smaller pulley on the alt. WHich should fix this issue.

Actually I'm going to go try to have the dyno done tomorrow.

I didn't fit on the dyno stand. lol They had to move a light out of the way.
I'm gonna let Matt guess what it was. Really think he would have the best chance given he knows what a cruiser with 35" tires on a dyno will do at the rear wheels.
Have to say it was a hell of a lot of fun watching those guys eyes light up when I had it in 3rd and mashed the gas.
I'm still a long way from having it tuned perfect. But it's a start.

Come on, inquiring minds want to know! Just how much gay horsepower and torque did it make?

OK OK I'll take a punt.

Would you believe me if I told you 100 hp and 154 ft lbs of torque?

Yes I would, I thought you may get a little closer to the 150hp but over stock 125hp @ the fly, a 100hp @ rw on 35's is dam good.
I may have to build a N/A 2FE for an up coming 45 project
I would but I also thought it would have been higher. If I ever get mine back from the machine shop and get it together (truck's been in pieces since October) I may have to get mine dyno'ed just to compare. Mine's an early open chamber head shaved .050 the block's bored .040 with dome pistons, balanced, 262 duration cam, 38/38 weber on high rise adapter with a mallory distributor and downey header. I'm hoping for around 130-140 at the wheels with 33's and 3.70 gears. I have no doubt it will move my aluminum tub truck just fine regardless.

Couple of things I could have done which would have given me better numbers.
I could have grabbed two of my stock 28" tires of my 55 and put them on. I probably would have gained 20-30hp on the dyno with just smaller tires. 35" is a lot of weight to spin up. I'm still running rich. So I think I have some more hp to find. I had to do the run in third gear instead of 4th. Had I run it in 4th and spun it up to 5200 rpms which was where my target I had set for myself. Those 35's would have been spinning around 140 mph. I would have probably slung them off and killed myself as well as destroyed the A/C Cobra that was sitting behind me.
Gary who was running the dyno told me right before I made my first run that if I slung metal out the bottom that he wouldn't be responsible. lol. After the run he said he was very impressed. He was thinking more around the 70hp numbers. He said said I had a torque monster for it being an inline 6. I asked what he thought the engine might have as far as hp. He said "What does it matter? It isn't real world hp." He said maybe 170-180. He said lot's of thing can change that number. Type of oil in the engine, tranny, t-case, diff. Gears, bearings, Diff ratio and of course the big one. Tires.
Told him I would be back after I did some more tuning. All in all a lot of fun. A 2f running at 5200 with 35's spinning at 95 mph is a hell of a ride. The 2f at 5200 becomes one solid very loud note.

I run 4.56 diffs and 35's.
I think now you have had yours on the dyno, and you well know how quick yours is with 100hp @ the rear you can imagine how 244hp feels
But to take nothing away from your efforts this has been a great build thread and far more use to all than mine ever will.
I think between our 2 builds we have pretty much covered what you can do with a 2F-2FE, there is no need to put a V8 in a 40 in my opinion.
Time for one of these
Best Regards Matt
