Maybe you will have to reinstall your old headers to fix this problem.

I went to that link and saw that the first post was gone. What was it about even?

I had a GT380 also! Quick little bikes. I got mine for 5 bucks. It did not run when I got it. It needed a seat, side covers and air filters but the rest was intact. Someone had stolen the parts that were missing and the cut some wires. An "expert" determined that it would never run again because of the cut wires. I put some power to the ignition and it was running with a couple of kicks. It did not run properly but it ran. I found the lower points to be rusted off so it was only running on 2 cylinders. As soon as I setup the new points the bike ran like new. It smoked for quite a few miles burning all the 2 stroke oil that had accumulated in the pipes from people trying to get it running before I got it. After I had it tuned properly It would do almost 120 mph!

Good luck with your GT!

What engine are you replacing this one with? Does he have one ready for it or is he planning on repairing the one it has? Does it have go go gears?

That must be for those mid 70s Mopars. Talk about lots of hoses on them back then! I remember some tiny little white vacuum line gizmo about the size of quarter that connected to the AC system failing on our 74 Fury III. The tech in Prince George knew exactly what it was at least and we were out of there with AC again for only a few bucks!

10 or so years ago my buddy helped me retune an OBD I GM fuel injection system. I downloaded the software off the net and he helped me change the fuel curves and ignition curves using an old laptop with a serial port and a custom DIY cable. We were able to make about 75 more hp over stock (a few other mods helped contribute to this number) after playing around with the setup. I am not sure if there is software or a hand held programmer for your setup or not. Maybe you will be lucky and figure out how to change some parameters to help fine tune your combination.
It must be running better now that you have put a few miles on it. Good luck Steve!

MEMBERS Project Cars in Progress / Gremlin / Newport Question Update

Excellent to hear you figured out how to fix your issue! Cool project! If all goes well it sounds like you will be able to drive it this spring and summer.
One of my friends that I grew up with had a hopped up Gremlin. His step father helped him build it after his dad passed away. It was a built up 360 with a 3 speed manual, 8 3/4" dodge posi with traction bars. That little car was scary quick! I am sure yours will be even quicker with your modifyed 401 4 speed combination. What rear gears are you running in your machine? I checked out your videos a few days ago. I love the sound of a fresh hot rod engine!
Now I need an adrenaline fix...I think I am going to go for a rip in one of my rods now that it is spring!
Are you planing on taking it to a 1/4 mile track for testing? Good luck with your project!

Only use higher octane fuels if your engine is a high compression engine and you are having preignition problems. The higher octane fuels burn slower to prevent detonation. So if you run high octane fuel in a low compression engine you can get worse fuel economy than running the correct fuel for your particular build. Your engine may need high test depending on how you setup it up. Some of my combinations changed when I ran a shorter duration cam with high top pistons...cylinder pressures went up so I had to run better fuel to make it work properly. Sounds like it still needs some miles put on it and some more tuning.
Good to hear that you are having some fun with it now!

Sweet car! My dad had one of those when I was little. Same colour. That would make a pretty cool hot rod!
Good luck with your new project!

Good to hear that you are on the road and testing her out. Depending on what clearances you used for building your engine it could be a bit on the tight side. A long as you do not over heat an engine that is built very tight you should be alright.
When I was building my third small block I set it up to almost the tightest specs that the factory would send out. I will not do that again as it took a few months before that engine would spin up in rpm properly. It never burned a drop of oil and still runs very strong after 18 years of use and some abuse but I would bet that if I tore it down I would find some evidence of too tight a ring gap...either some cylinder wall damage and/or broken compression rings. I put a high output oil pump on that engine (she made 120+psi on startup) and it blew up the oil filter on startup. That was the last time I used assembly lube...only fresh clean motor oil after that.
I pulled apart a 273 that had forged TRWs installed but they ran to small an end gap on the rings...all of them were broken but the engine did not burn oil even at around 80,000 miles on it.
Anyway, my point is that if you believe it is tight then take some more time before you expect it to wind up quick. It could of course be many other things...just giving you things to think about.
Good luck with your new toy Steve!

Good to hear you got her sealed up and are ready to roll again! Now you need to get out and seat those rings while the cylinders are relatively rough. When you get a chance are you going to take some videos of your new toy? I am interested in hearing how your cam choice runs.
Good luck Steve!

Timing chain cover leaking? Dang! I have had similar things go wrong...just takes more time. For some reason any work I did on other people's engine I never had oil leaks but mine seemed to always develope a small leak or must be Murphys oil leak law!

Most of the time learning costs a lot more! You will get it running soon!
When you do not expect to have to degree your cam this kind of thing can happen. I trusted the cam maker many times with success before I learned how to degree and index a cam. Once I understood what was going on I was able to play around with certain grinds. I was able to advance the cam timing on a couple of my builds to help build bottom end torque.

Sounds correct...but you have to know for sure that your cam is in phase. Do you have special plug or a way to determine the exact top dead center of number 1 piston?

Looks like a nice old truck! To bad they did not make more of the 4 door ones. Hopefully it will only take a bit of tlc to make it a safe and reliable truck for you. There are many after market parts available depending on your needs/wants. I love the fuel economy of the mechanical injected engines of that generation. I averaged over 30 mpg with one piloting some wide loads to Alaska and back with the last year of the mechanical engine.

Good luck with your project!
