I'm converting it mostly because there is hardly anything for performance parts(that I can afford), fuel consumption is no concern, fuel injection is so much harder to work on. Right now it will cost me $60 (or $40 for a code scanner) just to find out why it runs like crap and more to fix it. The cost to convert it will outweigh the tons of money I have to pay every time the EFI goes to hell. And there is no emissions testing here, so I can do whatever. I just want something to mess with and have fun, and fuel injection is not my idea of fun.

The archives have listed people touting the Comp Cams 260H teamed with a 390 Holley, Offy intake, and a set of headers. But I'm looking at building more of a torque/mileage motor. Comp Cams also makes a 252H. Would one of the Crane Cams split pattern cams be more appropriate? Is there a Wolverine/Blue Racer cam I should look into? Any 300 build advice would be appreciated.

The question is whether it's too much fuel or not enough.. grab some carb cleaner and when you stop pumping the gas give it a squirt down the throat and note if it helps or hinders the running. (start with a light spray you dont want to drown it.. if it seems to help work up to a heavier shot.) What you're doing is adding extra fuel (the cleaner), if it will run with the added then double check for vacuum leaks by spraying the cleaner at the intake ports, base of the carb etc. (Fire extinguisher handy of course!) If the extra makes it worse then I'd start looking at leaning things out more. I assume you didn't do anything with the distributor since it's on the opposite side of the engine from the manifolds.

Probably so, possibly mounted on the wrong side of something, or the hold down mounted in the wrong place? Of course the easy solution is to eyeball a similar truck but being uncommon that might not be so easy! You might also want to look at the cable as someone depresses the pedal to look for movement somewhere of the outside cable (should be stationary). Not trying to insult or anything, but could the cable have gotten stretched during the engine removal? I've trashed a few varying cables/wires/etc. over the years with the hoist. (See http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.thebigshow.com/BITPAGES/nascartools.html and examine the entry for engine hoist.. too true!) Might also want to see how much slack there is at the pedal end; for a short term solution you *might* be able to shim things there to achieve WOT. (be sure not to have idle become redline though!) I can move it open all the way by hand but not with the pedal. > Thanx in advance for all the help you guys can offer. > I can remember having to order a cable for my old Road Runner (due to engine swap with aforementioned hoist), and being my only car I made do with a small rope to the linkage and the rear window crank.. worked OK until I hot footed around a left hand turn and the lean of my body was giving it ever MORE gas... Funny now, but scared me pretty good 18 years ago. ;-) Some 3 years later I was waiting for a cable on my Dodge van and just left the dog house off and worked that Carter AVS by hand; bad part there was that it was the dead of summer and my trip to work was 20+ miles each way... my own portable sauna.

Working at a shop we probably average having to push at LEAST one vehicle around every day. You should hear the grumbling when it's a full size or a conversion van! Of course whenever possible I'll use my jump start box or tow strap rather than push (especially during this time of year)!

Just a thought.. go to the local super car stereo store; you know, the one that sells all the ear splitting' units in your area. I know at first this sounds strange, but there's a method to my madness.. these guys need awesome amounts of Amperage to make the Kilowatt(s) of power they want; two alternators isn't uncommon on full competition units.

Just want to point out to *NOT* use copper for lines; it will over time 'work harden' and crack. The ideal is still all steel, with rubber only between the frame and the engine though. (Steel doesn't like the engine jumping around on it's rubber mounts very much!)

I think the bell housing was a smart move too. If you're STILL worried get a bell housing blanket and wrap it around the housing as well.

I was going to use copper tubing for my oil pressure guage because I was worried about the nylon tubing being near the exhaust.

Actually all you need is a good ol' voltmeter and a jumper wire to extract codes; after that you post 'em here and ask for info. ;-) Seriously though I understand the situation. > The cost > to convert it will outweigh the tons of money I have to pay every time the > EFI goes to hell. Too true.. not so much on your vehicle, but it's easy to crack $500 even 1K on repairs on the later model vehicles. :-( (Can you guess why my vehicles are '79 '85 and '86?) > And there is no emissions testing here, so I can do > whatever. I just want something to mess with and have fun, That's what it's all about! If I could get away with it in my state there'd soon be a FI 302 in my B-II instead of the upcoming slightly modified carb'd 2.8. > and fuel > injection is not my idea of fun. It's part of mine (except for the really tough ones, but it's a good feeling some hours later when it's finally solved). Of course drivability is one of my specialties so I'm sorta biased. ;-) Anyway thanks for the info!! Feel free to post/e-mail if you need help!

If it carries a National Hot Rod Association approval, it's literally bulletproof. According to Summit Racing Equipment, the NHRA testing procedure for bellhousings is to spin a flywheel at high (drag race motor) RPMs in a bellhousing, mounted on a lathe. The lathe cuts into the flywheel until it grenades, and if any fragments get past the bellhousing, it fails. I doubt whether a stock bellhousing would pass this test (though it might be adequate for a moderate RPM motor). The Lakewood housing in the Summit catalog is NHRA approved to 7000 RPM. lordjanusz '94 F150 300ci....
