non CB 2.2 block with non CB 2.2 belt. I think the CB and the 2.2 non CB have nearly the same height, could be wrong. The difference between cam gears is neglidgable compared to the slack in the belt. Compared the square tooth 8v to the round tooth 8v and they are simmilar in size too. Also, you can not use the neon cam gear it has a different tooth count, I spent all morning counting, then I read 89acclaims post Does anyone make cut to length spark plug wires that'll fit the stock distributor? The distributor fits in the stock location OK, (it'd fit even better if my dad would let me grind in the garage : ( ) but the wires are way to short to reach down into the holes. I would not put the dist on the end of the cam unless I absolutely had to, looks like a lot of machining and a lot of oil sealing issues. If you can competently describe to someone how to machine a cam to accept a distributor (or machine it yourself) you can make an intake that will accept the dist in the stock location. Seems like its going to be a hundred years before I ever get enough money and free time to do this.

*edit* reread 89acclaims post, With the significantly shorter deck height, mayby I'll hit up the junkyard and find a 2.0/2.4 timing belt. If that belt fits I'd just need to find a common block with round toothed gears to stick this head onto and everything would be peachy.

You can get a set of custom wires for $70 or make a set yourself by picking and choosing wire sets that are of compatible size and trimming accordingly.

The 2.4 belt is too long, it has the same deck height as the 2.2/2.5 with two cam gears.;) I would check the 2.0 dohc and sohc belts.

If I understand correctly, the sohc uses a shorter belt than the 8v engines? I think someone will just need to bolt one of these heads on and nab a few different belts from the junkyard and mix and match belts and tensioners until something works. Does anyone know how much higher above deck that the 8v cam sits than the 16v sohc cam??

Take a belt with the proper size and shape of teeth. Set it up and cut it to the proper tensioned length. Take the belt to the parts store and compare all similiarly sized belts with identical shaped teeth. Take the winner home and test it out on the motor.;)

Just to give you an idea of why the belt needs to be shorter. On the 8v head, the cam rides at the top of the head pretty much. On the SOHC 16v head, the cam slides into the head from teh side and sits lower in the head. If it sits an inch lower in the head, the belt needs to be 2 inches shorter.

Ported, an sohc head can really flow some impressive numbers.

I would like to see some numbers on the SOHC and what should be done to the head by a backyard hack porter to bump up the flow to a proper rate. Pictures of a port job sufficient to flow as well as the DOHC is all I would want + a little extra while I am there ;) for the price of the $50 SOHC 16v head

I think we can all imagine the dumbass look on the guy's face at the parts store when you try to pull that one off, lol.

lol, duck tape, fixes everything. Back to the cam gear, do you think a sleeve could be made for the 8V gear so that it would fit on the cam? The mounting surfaces are nearly the same, the dowell pin looks like a pita to work around. the lowest of the low buck 16v builds

I don't see how it would be much different then making an adjustable cam gear.

I'm sending an 8v cam gear and the center of the sohc cam gear to Steve Mercier. He is making the adjustable cam gear for me and when we get it right, they you hopefully will be able to buy them from him. The sohc has a bigger gear than the 8v. I'm using a CB now for the main webbing beef. I'll solve the adjuster issue and if it requires a new one, then I'll build one. We are still setting up the new shop. You'll have some pictures and flows soon.

88-16v, you can make the ports wider and taller and that will help alot. The main issue with the regular sohc head is under the valve in the bowl area. There are some huge ramps that are there and need to be cut out. You'll see when I get the pictures up. I'll also show a race ported exhaust port I did that flows over 200cfm at .330 lift. (stock 95 sohc cam.) On cam selection, use either the 95 cam, or the magnum cam or you can also use the crane # 12 cam. Were also working on some turbo grinds for neon heads, but there a little ways out.

Did that with my lebaron upper and lower radiator hoses using an S intercooler. Worked great. Got an exact fit after comparing it to 5-6 other dodges. This is the same thing

Now if the 2.5l sohc 16v was a non-interference motor I would give it a try
