I found a 93 5.9L magnum cheap locally I may pick up. Let me here your 5.9L combo.
Do you have a gaol in mind? I'm gonna stay tuned to this one myself. Though my boat is a bitdifferent. It's allways good t read up on whatothers have. I have a '99 Durango. Leagal limitations apply. AKA Smog pipe test! That thing moves preety good for a heavy ride.
No specific goal. Im thinking cheap headers, RPM intake Hughes whiplash roller and a 750 double pumper.
I'm running one and like it a lot. I left the shortblock as it was in the Durango. I put on a Kevko pan, custom hydraulic roller cam, RPM Air Gap, Quickfuel 750 DP, 1-5/8 Hooker Comps through 2.5" X-pipe. Stock rocker gear, Iron Ram heads. I converted it to LA style serpentine setup and had the Iron Rams drilled for LA intakes. Times in sig for my full weight bench seat car.
The Iron Rams ported out? What are your cam specs? Rear gear and tire size? Converter stall? Nice numbers dude.
Thanks man! My original plan had been to use the stock Magnum heads, but they were cracked. Iron rams are the base model 1.9 valves, untouched as delivered for $800 a pair (plus drilling for LA intakes, the LA bolt castings were out of stock) ...If I were to do it again, I would have had the heads prepped to take a taller/better/beehive spring, I'm kind of stuck with the 1110s and they really aren't enough for this cam and 6200 RPM through the traps. Cam is 224/230 .536/.544 (high energy lobes). Currently 4.11 gear and 26*8" tire. Best time was run with 3.91 and 27" Hoosier Quick Time Pro. Converter is hard to say. Only footbrakes to about 2000, will go 3500-3800 on the transbrake. This same combo went a best of 11.88 with a 670 Street Avenger Holley in good air, but a ton of 12.00 and 11.9xs in the heat. When I was running the Street Avenger, I had $2800 in the motor air cleaner to pan, including headers, gaskets and 5 quarts of Royal Purple. Cheapest 11 second Mopar motor I've seen! ;) By comparison, the quickfuel was an expensive .18 - LOL! I don't have the sheets with me, but it made in the vicinity of 335hp at the tires on the dyno. The car has caltracs and monoleafs and Calvert shocks also. Its a very very streetable combo (except for the gear). There are some gotchas to the Magnum swap. I'm trying to put together a web page detailing all that stuff, but I pretty much suck at html and don't want to do something generic. Huzzah! (I need to buy a copy of this pic) I would really like to see what this combo would do in a more gutted/plastic bucket seat/no back seat/no wiper motor/no heater box type race car.
I'm running a 5.9 Magnum in my car as well. Granted it's not an A body, but still. The engine is a bone stock rotating assembly with stock (and possibly cracked) Magnum heads. Comp cam (P# 20-746-9) - 216/224, .506/.506, 114 (spec'd for turbo application) MP springs and retainers Edelbrock Air-Gap with 1/2" open spacer Quick Fuel 650 dp (Also tried an Edelbrock 750, but the 650 was better overall) Summit block hugger headers (1 5/8" primaries, 2 1/2" collector), dual 2.5" with x pipe LA front cover, water pump, with v-belt drive (custom brackets to run stock Denso alternator) The car weighs roughly 3000 lbs with me in it. Heavier than most people think, but I haven't tried to lighten it up any, yet.
Stock 98 Dakota R/T with a Shaker hood, gutted cat and a syms box on the back O2 sensor wiring. Didn't buy it for 1/4 mile. Bought it for hauling my Dart...and ass.
Adam, are you going to run the computer? Overdrive trans? LX, is an overdrive outa the question? I hear ya on the 4.11 & 26/27 inch tire. I have run that for a while. Limited Hwy. At least w/an O.D. trans, it would calm down to 2.83.
I don't want to hack on the floor to fit an OD trans, plus I got a lot of work in this 904. PLus I think I'd rather buzz the crap out of the motor than R&R the thing again. ha ha

Adam, i seen that ad. buy it great deal
Adam, We are running a 5.9 claiming 335 hp in a 2000 Dak as an I/CM drag car. Running R/T heads with no porting, M1 intake, 750 Holley DP, 10.5 Hoosier slicks, 4.56 8 3/4 with spool, CalTracs, weighing 3430 per IHRA rules. Best run to date was 11.21 with 1.49 60'. Any other questions, PM me and I'll add more. Bill
67 A-100 "the box" lol 95 360 factory 8.7 comp 55kmi re-ringed and bearing basicly copied the 380HP crate engine, ran 12.70s but its like pushing a peice of plywood in the wind i would think it would run low 12s in a a-body
I have a 5.9 380 crate motor in a 71 Demon street car. M1 intake Holley 750 DP Mopar eletronic dirstributor and box 410 gears MT drag radials 275 60s Header & x pipe 3" mufflers and turnouts 3000 converter run 4.80s at local 100 yard track Have not had it on a 1/8 or 1/4 mile yet.
5.9 Magnum, stock heads, Mopar dual plane manifold, Hughs roller cam, TTI headers, TKO 500 trans, 3.91 rear. 3700 pound street car, 12.34 @ 112.4 with Nitrous.
92 360 Mag stock bottom end and heads, completely rebuilt crosswind dual plane mp dizzy msd 6 al with blaster coil 650 double pumper cam 276/498 286/512 112 lsa double roller chain hughes single valve springs 904 w/3500 converter, 2 qt extra deep pan, cooler reverse valve body 3.91 sure grip 742 case 150 shot of gas hoping for 12.70's off the gas and 11.60 with the gas in street trim, thru the mufflers traction permitting of course I want to spank most stock vettes, camaros and mustangs
I'm running one in basically the same setup as LX guy w/ less cam and w/o the drag race setup. No healthy times yet. Still working out tuning & tranny issues.
Does a Dak R/T count? Mostly stock except K&N long tube breather and cone filter, Dynomax cat and cat back duals. Won't beat any new mustangs, but does pretty good in the 4200 lb CC truck With the 3.92's- Will boil the fairly sticky Hankook 101W's until I let off. Would do a hell of a lot better in a 1000 lb lighter car with traction!
Bump,X2. UOP made Hot Rod this month.The photo shows that RX transferring well.
