Do you have a cover over it? or is the Propane not like the Nitrous?

Yo Kyle: Sell the 400/tranny to someone else. At $75 into it, you should easily get your money back. If you want a quick (and easy) fix to your problem, get a replacement 5.0 that'll plug-n-play. If you really want to change engines, get a 5.8 (351W), since that will bolt up to your existing tranny. If you want to convert from EFI to carb (on the 351W), you'll have to change your truck's fuel system. Another thing to consider in changing engines is the EEC computer By far, the quickest and easiest thing to do is just replace the 5.0 you have now w/ the same engine type. That may also be the cheapest option. I am not an expert on the 5.0/5.8 small blocks, but I'm sure there are people on this list who can help you more w/ those questions. If you're really serious about using the 400 (i.e., willing to give up any hope of a quick and inexpensive conversion), I can give you a little more advice, but I am not an expert on the later model trucks (post-'86) either. Good luck.

I have it advanced as far as I can go and run premium. I did run a mix of 80% of 93 & 20% of 112. this seemed to help a bit, but is there a way to adjust or tune the air/fuel mixture without having to get a complete custom eec tune? Might the o2 sensor cause this problem? Nephew Phred wakes up (Thank you Uncle Les): In your case there are two methods I can think of to reduce the fuel intake. 1) drop your fuel pressure and 2) get lower fuel flow rated injectors. The O2 sensor only reports to the PCM what it sees, its the PCM that actually tell the injectors when to activate and for how long. If you are indeed running rich then you are accelerating the degredation of your catalyst and your O2 sensor. A plugged cat is going to cause you restriction which is the last thing you want. If your Engine Coolant Signal is insufficient (by the PCM's opinion and not anyone else's...) then the PCM will force the mixture rich because it will want to hurry up and light off the cat, O2 sensor, and get the engine to normal operating temp ASAP. Typical ECT voltage for most EFI Fords is around 0.7 Volts to 0.9 Volts. Anything significantly higher than that will certainly lead the PCM to believe your engine is not completely warm. On later 90's trucks this signal is on the Lt. Green/Red wire found on the ECT sensor, for the sensor location see the aluminum thermostat housing. Careful because the Inlet Air Temperature sensor is relatively close to this area and is essentially the same sensor with different color wires. It measures the temp of the air inside the intake plennum. I am curious as to why the blend of gasoline? Have you bumped up the compression to 14:1 more or less? Installed a "performance" chip? Here I go again asking more questions than answering, sorry Chris, but maybe someone else will see something I am missing.

If i can go a little bigger how much? ---------------------------------- I have 31x10.5 on my 89 f-150 4x4. i got different rims to put them on, but they were still the stock size. i think i could still fit 32x 11.5 on my truck and would go back and do it if i could. 33s might be too big. to put those on you should get a lift or have a stiff suspension.

I converted from speed density to mass air using the FMS mass air conversion kit which includes a new pcm calibrated for the 30lb injectors and 80mm mass air sensor. i have the gt40 heads w/fms 1.6 roller rockers as well as gt40 upper & lower intakes. i'm running a comp 4x4 extreme cam with 110 deg lobe separation. I'm using 10:1 aries forged pistons & alum h beam connecting rods. the crank assy was internally balanced. heads were decked aprox .010. i'm also using a 65mm throttle body and a Paxton fuel pressure regulator. i had to install an inline bbk fuel pump to feed enough fuel (maybe too much). i'm using the factory fuel rail. this isn't the entire list, but well enough. i have checked my fuel pressure with vacuum it was at 32 psi, i was told to drop it a pound or two. i'll try this and see what happens. i'm taking a break as i type from changing the #4 valve stem seals. while doing so i noticed the spacer i have between the upper & lower intakes has much gas absorbed in it. about the only thing i can think of is the pressure, but your note about the temp may be valid as well. i installed all new sensors but i'll give it a check. cheers On Wed, 14 Jun 2000 14:17:02 -0600 Fred Moreno writes: > chris h wrote: > > 3 - I also seem to be running fat. are there any recommendations on > how > to lean it out.

Chris ------------------------------ Date: Fri, 16 Jun 2000 14:46:05 -0400 Subject: running fat From: chris hinckley I believe i posted earlier that i'm running fat with the new stroker. so i went and bought a pretty good injector continuity tester and fuel pressure gauge. i checked the pressure with no vacuum and came up with 39psi (within range). I hooked up the vacuum and still 39 psi. I figured the psi should have dropped some due to the vacuum. I have vacuum pulling through the hose going to the regulator so i check to see what's up. it looked as though the vacuum line had a 90 which had it effectively pinched off. with no vacuum to the regulator could this create a rich condition? i do not seem to be getting the black plum today. this leads me to my next question, i'm using a steel braid sleeved rubber vacuum line, does anybody know of a source for factory like custom vacuum lines? thanks much, chris h ------------------------------ End of 80-96-list Digest V2000 #114 *********************************** ---------------------------------------------------------- Ford Truck Enthusiasts 80-96 Truck Mailing List Send posts to 80-96-list ford-trucks.comIf you ever want to remove yourself from this mailing list, send an email to: listar ford-trucks.comwith the words "unsubscribe 80-96-list" in the subject of the message.
