Thanks Rick. DMHINE's has a geat looking Maverick. Terry, you have a great idea, but when you mention going with a F.A.S.T. EFI System, a Sequential Individual Cylinder Control unit will cost around $3500.00. Bennett Racing has them. Then after you install all the goodies, you'll need to get it tuned and dynoed. That will probably cost around $600.00 to 800.00. If you need 19# Ford injectors, I have a set. What type of feul system are you going to use? I like your project. This is the same thing I'm looking at for my truck. Thanks, Ken
Ken, I was probably only going to use the FAST controller. Injectors, fuel rails, throttle body will be from others like Accel, etc. I intend to use a speed density system instead of mass air flow (cheaper and I can control the setup). Nothing is set in concrete. The 2 bbl conversion may be as far as I go on fuel delivery. With a header, cam and 2 1/4 single exhaust, I'm not getting the maximum efficiency out of the engine setup. I'm not sucking in enough air and fuel to get any real power out of the header. I bought the car with this engine and exhaust setup and now I need to tweak it. A 280 cfm 2 bbl, 3.73 gears, and AOD will make that entirely different car. I should have acceleration equal to or better than a stock 302 and I should get way better gas mileage than the car ever did as a stock six-banger. My car is being painted. You ought to drive down from Kennesaw and take a look at it. I'm an hour away and the car is another 45 minutes away. Good trip for you on a Saturday. C'mon down.
terry, have you compared that setup to say a TBI style injection system or maybe the EFI setup of the 300 straight six? just curious on the mods it would require to the intake manifold, since it is single piece. the TBI setup would still have the manifold volume as a weak point, and the 300 EFI would have to be modded into it as well, just wondering as ive been curious on this. still trying to find a way to mod a 390 to EFI as well for going up and down the hill (9k foot varience). course im not anywhere near knowledgeable on EFI setups.
If I had an Aussie or Argie head, TBI would be the ideal way to go. If an adapter can be made for a Holley/Weber or an Autolite 2 bbl for these log style intakes, I guess an adapter could be made for a TBI setup. Modifying the intake for injectors will be the pain in the butt. IF, and this is a great big, wishful thinking if, the head and intake combo was billet, aluminum, steel, or just about anything other than cast iron, you cut the log off and fabricate something else to go into its place. For your 390, a very good solution is Edelbrock. I think they will take any manifold they make and modify if for their EFI setup. It ain't cheap, but it will work just fine. Holley's ProJection system will work on 390 manifold. I have a friend that just completed a restoration of 1968 Galaxie convertible. He had a 390 built (391 HP @ 5000 rpm and 492 ft lb torque @ 2500 rpm - he needs a set of aftermarket heads) and going to put EFI on it. I will ask him what setup he is using. I know he bought it aftermarket. I also ask what he paid.
On the original subject of a header: I think headers are always a great idea. Even if you can't or don't beef the head/intake, a header is going to add HP, TQ, and MPG. It will also lower operating temps. I agree with previous posts on the dual exhaust: If you get a dual header, any more than 2" exhaust pipes are wasting torque. If you get a single, then maybe 2.5" would be cool. On the muffler, I know you don't want loud, but you can find something mild with good flow... Maybe some turbo type. Good luck Dave
Hey Terry, thanks for the invite. I need to get some more work done on my Maverick to get it street safe. Front end tomorrow, then I am going to have an exhaust put on it like dmhine's Maverick. On the Speed density subject, that is what my Lightning is stock. Your cam selection should have a 114 LSA. If you use a smaller angle, the computer will have a hard time with the idle. The trucks won't idle with a 112 LSA. Afte I get my new engine, I'll keep the Speed Density setup and use a Tweecer module to adjust the engines parameters. Post pictures of your Newly painted Maverick. Ken
i'd do a 2 inch pre muffler 2.5inch on the way out only if you had some nice mods to it.. cam header intake etc. as far at the K&N giving 10 hp someones been reading to advertisments... j/k don't we all wish it gave that! i'd add a X-pipe too to shut the thing up if you want quite. btw you ever get the PM from me to link for the contact for that head? never heard from you if you did.
Some may consider this blasphemy, but since were on the subject of inline sixes. Has anyone ever considered swapping another kind of i6 into a Maverick, maybe one that already has a ton of aftermarket support? Im no I'M NOT talking Chevy. Im talking import! You can get a Toyota Supra 2JZGTE engine, ecu, and 5spd trans for around $3500 if you look. Even stock its a tuff, stout, powerful engine. Its already EFI, DOHC, and you can get anything for one. And it doesnt take alot to get some really respectible HP. If your worried about it being a Toyota, shave the top cover and slap a FORD emblem on it lol! Just an idea...dont kill me.
I have seen that Toyota in some classic Mustangs. I don't exactly care for it, but it is a good swap for a driver. Ready for more blasphemy? I've been thinking about a small, 4-cylinder diesel, with a turbo in a daily driver Maverick. 50 mpg sounds purty good these days.
Terry, you come up with some interesting ideas. Turbo diesel Maverick. After spending $33.00 on 13 gallons of gas, that is not a bad idea. Ken
Someone's already done the Toyota Swap? I havent seen it but I would like to check it out. Anyone know anything about it? According to Derrick I'm beating a dead horse so I need to see the dead horse Im beating lol.
Yes. But, If I remember correctly there wasn't anything available at the time. Of course, I could be remembering something else, but I highly doubt it since I am so young and spry.:bananaman
