want any ideas on what type of intake to put on a 92 302 and bigger throttle body.

There is not really anything out there for that EFI set up it is speed density, 93 they went to mass air flow in trucks and there are all kinds of mustang parts out there but not for 85-92 302 truck.

Look into the Lightning intake. Not to sure, but I think it will work. Also look at your local junk yards for a newer computer and then you will have more options for the whole top end. May cost a little more but makes for more veriaty for parts.

A bigger TBI unit will reduce lower RPM torque even more which 302's do not have a lot of anyway. I suggest that you may be looking in wrong places here and if more power is your goal you should be looking at a axle gear swap and not a bigger intake.

Snoman stick to the question. The man asked about intakes not gears or how to make more torque. I've personally have owned a number of 302s and they have always had enough torque to get the job done plus more. Maybe you should stick with Chevys

Excuse me but why does he think he needs more power duh.... Because he probably has stock gears and big tires and it is a slug at time. No carb is going to fix that and a bigger one will reduce low and mid range torque. You are the one trying to do some smoke and mirrors here not me. BTW, a 302 is not torque champ and if you think they are it is because you have low standards. It has a very short 3 inch stroke with a 4 inch bore and the geometry here DOES NOT support good low RPM torque.

I'll bet you licked those windows clean on that short bus, didn't you. The man never said ANYTHING about big tires or low torque. He simple asked about intakes, that's it. Maybe it's just a two wheel drive that he is trying to race, ever think about that. In 92 they only came with EFI, not a carb, and if it were a carb then I'm pretty sure that he wouldn't have asked the question sense there are about 30 or so carb intakes to choose from. I never said anything about the 302 being a torque champ anyway. All I said is that I have never had any torque problems with my 302s in the past. Try to stick to the questions or just stay off this site.

Why is it you have to act like a child when presented with facts that you disagree with? In a large bore short stroke engine the rod angularity and the velocity of piston vs size and speed a flame front in cylinder produces less favorable leverage and torque are lower RPM's than a longer stroke engine of same displacement. A 300 six will easily out pull/torque a 302 at lower RPM's because of different geometry to achieve same displacement. I have seen your type before, install big tires and stock gears and think they can fix/restore lost power due to geometric mechanical factors and fix it with a carb, aircleaner or dual exhaust. It does not work that way because with your combo it is now like using a smaller pry bar to displace same load which means less peak effort can be applied. Deeper gears restore the mechanical advantage, not a carb or aircleaner or exhaust. You have the illusion of a HD 4x4 with big tires but it is just that a illusion because it is now lighter duty and has less peak pulling/wheel power than it did before if you did not regear it.

A lightning is a 351W in the early version and though similar to the 302 the intake will not work. You may find updates in Ford motorsports to convert yours to mass airflow. The problem with 85-92 302 trucks being speed density the computers have preset values(does not measure incoming air)and is not sequential EFI(controlling fuel injectors individualy)your 302 fires 4 injectors at a time.The reason Ford did this in early EFI trucks was because it was cheaper to mass produce and provides a flatter power band in small ci. engines. Mustangs went strait from carbs to sequential mass air EFI.If you can update the system to mass airflow then your modification availability's are greatly increased. You may be able to get the things from the wrecking yard from a 93-96 F series or bronco 302.

On the early 302 with that system you have. My first question is what camshaft do you have? One of the problems with those trucks is in the cam timing and cam profiles. I wouldn't change your intake until you explored your camshaft potential. I did a 302 for my dad in a f-150 4x4. the truck made 19 to 22 miles to the gallon on 32" tires. It was a good truck. I just basically fine tuned everything gasket match all ports from the exhaust up through the intake. Leave no stone unturned type of situation. Had a camshaft cut specifically for him with modern cam profiles at that time. A lot of btm and midrange on cam He only turned 3500rpm at max. My only regret was we should of put more compression in engine but had to run 87 octane. Ran E5TE heads and did a nice job on heads on porting. I know this isn't the answer you want but its something that needs to be explored and most people do not and wonder why certain truck just run really well, its the little things all adding up to the finished product. One other problem with the 302 is intake runner length is short and that is a natural design problem. Runner length is key to making torque and vaporizing the fuel before it hits the combuation chamber. The further you get those injectors away from the combustion chamber the better with a 302. I'm going to install 302 in my jeep and this is a concern for me when building up the 302.

It is totally amazing the length people go to thinking they can transform a small motor into a torque champ to make up for tall gears and big tires when all they need to do is simply regear vehicle. Even a 302 can do well IF it is properly geared. BTW, for lower RPM torque, velocity of mixture is important. Big long runners that "tune" in at upper RPM's reduce lower RPM torque.

I've been told those AFR 165 work really well in 4wd application. Awesome throttle response for 4wd's. Been looking into those heads for my little 302. Want a 302 with good smooth torque and fuel mileage.

i would have to say just think it out. look at your intake system and sensors and custom make something you would be surprised at how cheap you can make a decent performing intake like a cold air intake. and snoman shut up you are obviosly an idoit when it comes to for. i have owned a few 302's in pretty much stock shape i know they aren't the biggest baddest ford motors out there but they do have low end torque and longetivity i had one that lasted a shade over 500K and it was abused. and my current '94 f-150 w/a 302 has dragged a chevy 350 bumpers chained and both trucks at that time were completely stock.
