As my luck would have it I have to take my car back apart. I ran it at the 100' drags a few weeks ago and all was well, it was running awesome with no issues. I needed to do some 3rd/4th gear pulls to datalog some more and it went lean so I backed it off. I noticed some coolant had spit out of the overflow which is a telltale sign of pressure in there (blown headgasket). So I drove it again and found out the reason for the lean condition, my fuel pressure was dropping at around 5000-5200 rpm. So I ordered a 340lph pump, some ARP head studs, bought some new gaskets, and will start tearing it apart again soon. As many of these cars I have mess with I always have the bad luck with mine. I should have gotten a larger pump in the 1st place but I assumed the 255lph would be enough for the power I would make. I was also seeing 12lbs of boost too which is a lot for the 3.33 upper with heads/cam/intake. $$$ is tight since I am still out of work but trying to get this done asap.
255lph high pressure pump made by High Flow Fuel. No FMU it has 60lbers. Thankfully I have a fuel pressure gauge in the car. I am going to check the voltage at the pump today and make sure it is not getting a huge drop. Only other thing it could possibly be is the regulator but usually if they go bad they won't work right period.
Shit happens, and usual to me LOL. It is a little bit of a downer. The car had been in the garage for a year in Nov. almost. I have the time now not working which I never really had so I want to get it fixed while I can.

ok. Seems like 255lph would be enough flow. For reference, I'm running a 190lph in tanks and a trex which flows the same at higher pressure for the fmu and am running over 500 to the wheels.
Good luck with the gasket change, they're no fun for sure.

Your still running an FMU? Yea it is hit or miss with the 255lph pumps some guys have enough for 500-550 some don't. I checked the voltage at the pump and I am getting 12.84 steady. That's with it showing 14.12 at battery. I have no clue what it is making for power, pretty good. It actually felt faster than it did with the built 331 and 13lbs on S-Trim I had before. Why or how I don't know. Yea, I hate doing headgaskets. I am going to get the heads checked and maybe resurfaced too because I don't want to take them off again right away haha.
Yeah, I'm still running 36lb injectors so I have to run the fmu. Still running the stock fuel rails too! If you have a precision straight edge you can check flatness yourself. Good luck.

Yea that is what I plan on doing I just have to see if my father still has one laying around or not. I am going to check my lines for any kinks as well. Not much else there can be, this is the 1st time I have ran out of pump with a car I was working on or owned. When I had the 331 it had the 255 intank plus 255 inline but ended up unhooking the inline after it had some issue where the fuel pressure was irratic. It was fine with the 255 which is odd it isn't now. It does feel stronger now than it did though which makes no sense. Built 331 with ported TFS heads, Holley intake, etc...idk...

Gonna need atleast a set of 60's for the Dart! Where is the progress thread mister??? How you and family have been well.
Man Dave.
Sorry to see your having problems. Always something i tell ya. Just part of the game... Post some pics to show people your progress and to give them a look at a clean Fox head gasket job. Alot of people can learn from a visual. MAybe it will deter people from paying other people to fix there stuff.
Definitely! I assume all else is ok but will have a better look today hopefully. I just use the typical 8548PT2 gaskets since they hold fine but let go if something isn't right. Rather have a $18 gasket crap out.
It is ok to use a head gasket as a fuse as long as the fuse doesn't cause more damage when it goes. For example, crossfirung between cylinders and melting the head. Ouch.
