streetjeep2.5

Found at U Pull It, Kansas City

Me also, first and only comanche. Coming up on 10 years now.

Based on what this links says http://www.4wd.com/jeep-advisors/cooling-system.aspx can too many rows be overkill? It speaks the amount of fins and space between the fins along with flow as the critical balance needed. Can a 3 row cause too little fin surface and air movement over the fins for adequate heat dissipation?

Whatcha doin for coolin????

dunno, but you need a selection of torx bits anyway cuz they come in handy at times, so head to your local tool supply place and buy a set and use the one you need! :brows:

While I like staying basically true to the brand also, I "justify" my swap by saying, "well, my Jeep is an 87 and during that time frame (a year earlier), they did use a chevy engine, the 2.8! ;) So, I am staying kinda true! Its a v- chevy, just 8 instead of 6 cylinders! :brows:

That is my plan for a 327 in my short bed 4x2. Plain stock on the outside, pure business inside. In the 1960's at least in Oregon we called them "sleepers." Engine will be stock everything except for a Pure Energy CompCam (lift and duration barely more than stock), Weiand dual plane intake with a spreadbore quadrajet, and Sanderson Shorty headers (that's what Novak sells for their Cherokee/Comanche sbc conversions, but I found a different Sanderson version that's less expensive). Online dyno says will bump the stock 250hp up to 300hp. That combo should even increase gas mileage over stock. Want to do standard trans, and will first try a NV3500, the gm 4.3V6 version of the NV3550. It will be handling the upper limit of its torque rating, but it will be a daily driver. Being a 4x2, no mudding or climbing and don't intend any drag racing! Pulling a light trailer and hauling stuff at times, but that's it. Still, guys, what about cooling? Fans and a two row version of the stock one row 4.0 radiator? Cooling surface is the issue. It is still less than what SBC's used. I don't want to spend what Novak and AdvanceAdapters want for their conversion radiators if I don't have to. So, you who have 350's or 5.2's or 5.9's in your 'manches and are driving them; whatcha using?

Whatcha use for radiator, and how is cooling?

Had an english springer spaniel that would continuously chase the homing pigeons our neighbor owned. They would fly around over an open farm field behind our houses and for half an hour to hour that dog was on the ground running where ever those birds in the air went, and then come back when they landed in their pens with tongue dragging the ground! Speaking of a Cocker, we had one when I was a kid that charged a racoon. NOT a good idea! While in florida our G shepherd jumped in a small canal after a bird, and an unseen before small gator dropped into the water. My wife wanted me to go in and get our dog! Thankfully the dog responded to our call and got out first!

I have been on the trifive website (55-57 chevies) to get good 327 rebuild info. Recent discussion there really recommended Dynomax over flowmasters. Flow as well but far less resonation that ends up in the cab. I have flowmaster but will go with dynomax

Got mine from here about 10 years ago. Don't know if they still have them, but still in good shape. I garage it as much as possible and keep vinyl protector on it. First pic is about 5 years old. Second more recent. http://www.downeyproductsnortheast.com/sst.html

Yea, I think MJ's are addictive, even to the non-owners. Being a pastor, I conducted a Baccalaurate service at a high school. On the way out I saw a few students taking second and third glances at it. Now, remember, mine is 4x2.

How does the fill tube fit with the stock tank being in front of the axle and the TJ tank going behind the axle? I would hope a REALLY long connecting hose will do it. Have to see tank and go from there. Gee. Get an extra gallon in the connecting hose! cool!

I am probably a couple of years away from getting this done. Won't do it until I have everything except the exhaust work in my garage, the engine rebuilt and ready to go in, radiator needed, etc, etc. Sorry!

Since I don't have a bell housing for my 327, and the cost from Novak for the 3550 to chevrolet bell housing adapter and the cost of a chevy bell housing, probably go with the 3500 that has everything there, and no machining of bellhousing and tranny input shaft will be needed. Only plus to the 3550; I could take it off only if needed, and not bellhousing with it. Can I come up with a 3550 that will make the cost equal? Shall see. Besides, bet its a LOT easier to find a 2wd 3500 than a 2wd 3550 ;)

97-06 TJ. The later model tanks are different on the TJ. I think 04 or something like that. ChryCo added some weird emissions stuff to the top of the tank. I used and 97 pump with a 01 tank. I went with a 22? gallon tank. It was the bigger of the two availble for the TJs. Thanks! I shall look for a 97-03 tank. Wouldn't mind a 18 or less gallon, though, since I'm shifting weight to the back of the pu. Stop more, but ....

3550 (which I don't have) is the NV jeep version of the NV3500, right, and basically the same tranny in its innards?

Are you talking the actual TJ (97-2006) or simply the wrangler, no matter the year? IRT fuel pump, will be using the chevy mechanical on the engine, so will have to figure out fuel level only.

Now that be real cool! Thanks! It take you you have experience with this? Long or short bed make a difference? Mine is short.

Ya mean just eliminate it????

To quote a little pull toy my one daughter had and it still works (she is 39), "oh, no! I'm falling apart!" :ack:

Naaa. No granny. 4x2. Daily (except during winter) highway driver. I am thinking about the 4500 but it's a cast iron case monster (200 pounds w/o fluid) and I was hoping the 3500 aluminum cased and lighter tranny would work. 4500 seems to have been used behind the bigboy v8's, 6.0 and above and 8500GVR vehicles. That's where I am caught: Wiki "seems" to indicate the 3500 was used behind some 295 hp and probably 350maxtorque 350's, but I have also read it only handles 300max torque. Seems mutually exclusive. The later 3500's did undergo some changes, like larger bearings, etc. Could they have done this to beef them up for higher torque? Havta talk to da chebby guys!

Again, with putting a 327 in my mj 4x2, I want true dual exhaust. Can't with the gas tank where it is. Since I do no 4 wheeling, I am considering moving it to behind the axle under the bed where the spare tire used to be, properly protected with a shield, of course. Measurements seem to indicate it will not hang down too far. Shouldn't be any fuel pressure problems because I will be using the mechanical chevy pump and the gas tanks used to be back there. My only concern, then, will be clearing the brake load sensing valve on the left side with a tail pipe over the axle. Can it be relocated? Will the the older non-c clip D35 system (as per picture in viewtopic.php?f=2&t=30207 ) provide clearance?

I'm in the sssslllloooowwwwwww process of eventually dropping a 327 in my 87 4x2. Know what I will do with engine and it will, according to those in the know on chevy engines, bump the stock 250hp up to about 300. Considering the NV3500 5 speed that was used behind the chevy 4.3 v6 in compact and full size, and maybe, but I'm not absolutely positive, behind close to 300 hp 350's in Silverado's. That's what I find from Wiki. It is listed as the NV3550 behind 4.0's, etc. I will shoot for the S10 version because it's close ratio, not wide, and I want the overdrive 5th gear because this is a highway rig, a daily driver, and with leaving the stock Dana 3.55 ration in the rear at least for now, It will not be hotrodded and gear 5 will drop my rpms from near 3000 now at 75 to hopefully 22 to 2500 at cruising speed. Thoughts on using the NV3500????
