like the MSD unit? all i see is the distributor and the previous owner isn't exactly savvy when it comes to modding. i don't think the PO was serious enough to even consider something like an ignition box. he considers NAPA parts to be aftermarket modification lol.

btw, i'm going to start shopping prices for paint tomorrow morning. i'm fuckin stoked. hopefully, i can get paint started by the end of the week.

also, i drove this car ALL day today. it ran smooth as hell other than a couple minor annoyances. for one, the fuel pump is awfully loud. two, it seems like i have to let the fuel system "prime" before i try turning it over. and three, it doesn't want to seem to want to hold an idle until it gets warm and even then, if you leave it idling for more than 5 minutes it'll die on you. the thing that jumps out to me is that all of these three issues are fuel related which makes me think the 5000 rpm "rev limiter" might be fuel related also. any thoughts?

LOL. That rules my theory out then. Does it sound like an actual rev limiter or does it just start missing?

101fng · May 12th, 2011, 03:24 AM

it sounds like a rev limiter but in a slightly slower rhythm and the rpms refuse to go any higher.

hey, also guys, keep in mind, i'm coming from the modular world and to me, if its not controlled by a computer then i don't know how it works lol. that includes rev limiters. obviously, in a carb'd setup, the limiter is mechanical, but i have no idea how the mechanics of that would work. school me.

I'm new to this whole Ford thing in general so my means of help stops here lol. All of the carburated SBC's we run in our trucks just float the valves once they rev so high.

I was told in another thread that modifications can screw with the stock gauges, that'd be something to keep in mind as well. May be revving higher than you think??

my stock gauge is out lol. i'm using some cheap autozone tach for the time being, but it might be screwy too. idk.

It doesn't have to be mechanical, depending on what's done to the car. My car has a limiter because it has an MSD box. Some people hid them under the dash, so you may look around for one. That's why I said it may have a rev limiter. There are many cheap rev limiters that can be wired into the stock distributor.

ok, update.

i went to get a quote on paint today but the dude at the shop was being lazy and didn't want to go outside and look at the car since it was pouring rain. after describing the condition of the body and some other details, he gave me a very rough estimate of $800. sounds like a deal to me. i'm not sure how good these guys are, but the dude said they were booked for at least the next month so they at least have some steady business.

also, i was in dead stop traffic today because of an accident. i was running a lil low on fuel so i shut her off until traffic started moving again. well, after sitting there for a good 10 or 15 minutes, traffic started moving ahead so i go to crank her over. well, i let the fuel system prime for a second, then turned the key, and nothing. it didn't even try to crank. i tried this about three or four times holding the key at the start position for a good 5 or so seconds and still nothing (and i mean nothing, not even that little cough sound that starters make). well, i tried it again and just layed on that key for like 10 seconds and then it coughs, cranks, and roars to life. wtf? starter i guess. i mean, the guages worked and i could hear the fuel pump, so i know it wasn't electrical. and if it were fuel, i'd at least hear it try to crank over. so... what starter do you guys recommend? i see that MSD starter alot but its a lil on the expensive side.

You have now been exposed to the downs of troubleshooting a carb engine lol. Just get you a descent little high torque mini starter and that should resolve things. Has for me in the past anyway.

Lol.....downs of troubleshooting a carb'd engine? You kids these days make me laugh. A carburetor is such a simple, basic design. It's so funny to hear people say stuff like that, just because they don't know what they're talking about. I'm going to go out on a limb and say him turning the key, and the car not cranking, has nothing to do with the carburetor.

I would check the wiring and ignition switch before you replace the starter.

Refer to page one as far as the carb'd engine comment goes, that's what I was referring to. Having trouble with that and now the starter issue. His luck seems to be as bad as mine when it comes to owning older stuff.

The starter issue is irrelevant to that though, I will agree. I'm not exactly one with words. Please find a place in your heart to not hate me.

I wouldn't say I'm having bad luck lol. I love this car! The fact that she has her little quirks makes it even better. I'll check the wiring and ignition switch but I really think it's the starter. It's just a slow start and then that one particular issue kinda sealed the deal.

sometimes working on something is half the fun of owning it. I've owned countless carb'd SBC's and it always seemed like something needed tweaking constantly. But I guess throwing worn out parts on top of more worn out parts could yield that result. Gosh damn hillbillies and their mud trucks. I tell ya.
