I have an unknown brand 6 pass trans cooler that's 12" x 7 1/2 x 3/4. I'm hoping for a 450 hp 318 turbo. I have a 2800 stall torque converter , 904 with new internals. Also have a large sump, finned oil pan. Is this setup big enough to cool this trans or should I plumb into the radiator (a down...

Rebuilding a 318 mag for 10 psi of turbo boost and I'm having problems disassembling the stock lifters. The clip and pushrod cup comes out but the valve and spring are completely stuck on all but one lifter. Even after relieving the pressure with a scribe poking the ball valve. What can I...

Hey guys, was using the search engine but didn't get an exact answer. I'm losing .035" lift through pushrod geometry with a roller cam small block. I've tried many different lengths of the rocker adjuster, right now I'm showing about 1 thread on the adjuster. I have a .534/.538 lift cam, and...

Hey guys I have a set of 273 rockers going on my 360 with RHS heads. I have a roller cam that has a lift of .534/.538 Having problems getting the perfect pushrod size. I'm using a checking lifter and adjustable pushrod. I think my rockers ratios are not consistent from one to another. I...

Which selective discs do I need to increase the clutch pack end play? I'm at .013" My 727 book says reduce the pump-to-front clutch disc but I have the smallest one in the there. And the front-to-rear drum disc is the largest. This is how the PO had it. I did have to change the front drum...

Hey guys been reading a lot about rebuilding my 904 and have jumped in deep. So I have a later model with a 5 clutch front drum. Measuring the dry stack of clutches I get a clearance of only .020 with a flat snap ring. I realize this is way too tight and I need more like .070 I asked the...

Hello all, looking for some ideas on the rear quarter replacement on my duster. I need some tips on where to start cutting. The rear quarter had a decent size dent down low and some rust. I ended up taking off a LOT of bondo, 3/8" in some places. I don't know how it didn't crack off because a...

Hello all, having a no oil pressure condition with my 360 that has seemed to worry me more and more and need a little guidance on what to do with the engine as I have multiple problems. This is going to be a long post so please bare with me. A little history first, bought the car a little over...

Looking for a decent set of adjustable rockers for my 360 build and I've came across a set of 273 rockers, shafts, and spacers. Any harm in throwing these on? I'm sure I'd change the shafts for new ones since the rockers are off and out of order. Should I reface the valve tip contact area since...

Hey all, have a LA360 in a rebuild and have a comp roller cam that needs a bronze gear for the oil pump drive. Deciding what driveshaft to go with is giving me a headache. The motor and cam has been ran about 3000 miles before the heads burned enough oil and well..I'm rebuilding everything a...

Have a 360 short block in the machine shop that I need a pair of heads for and I have a few decisions to make and I would love some help. Going into a 4x4 Ramcharger, want a strong, powerful truck but nothing crazy. At 6200 ft. altitude. Specs for the short block are: 92 360, 4.030 overbore...

Well this was an interesting experience.. I pull the duster out onto a rural highway, manually shifting, 1-2, 2-3. Going about 65mph and I feel something funny, like a lack of power, I think it's a fuel problem, maybe I bumped the fuel pump switch by accident, nope. I hear sqealing tires and the...

I have one pushrod that isnt spinning at all after a cam change on the Duster Broke it in with moly grease, zddp oil and some additive, 2500 varying rpm for 35 min. Took 3 tries to get there, never cranked and cranked..always started up fast. Runs and pulls good. Idle has a slight miss but maybe...

Assembling the engine after a cam swap on a 360. I find a cracked rocker shaft between #1&3 cyl. Unacceptable, I find a replacement shaft but it would be on back order for over a week. Hughes banana groove shafts? They look good but I have an old set of Cat roller rockers which have roller...

Have a 73 Duster that has a/c, just not hooked up. I picked up the car and it didn't have a heater motor, just a blockoff plate - weird. So I'm looking for a motor online but nothing looks like it would fit the car. Any suggestions? Here's what I'm working with:

Installing a MP .528 solid flat tappet into a 360 and I'm having problems degreeing the darn thing. I'm getting some funny numbers while finding the intake centerline. Following the directions that came with the cam on how to degree it I should be installed at 112 ICL. I made a degree wheel from...

Hey guys, putting in a new cam in the duster after the old one went flat. It's in a 360 and the cam is a mechanical flat tappet MP. MP says to remove the inner spring on a dual spring setup, which I have. Mine have an inner spring, a dampener, and the outer spring. Do I remove the dampener too...

Took the duster out for a ride and some carb, kickdown linkage adjustments and noticed a LOT of smoke out of the passenger exhaust. I have headers and duals. Ran a compression check and #2 is 0-30 psi. Bubbles in the radiator. Pulled the valve cover and the intake roller rocker adjuster was...

Been wanting to upgrade the ignition on the duster. Right now it has a Mopar chrome box with a 2 ballast setup. Wanting a 12v to the coil setup, probably a larger plug gap. I have a 12v coil already and an MSD box. I've used the MSD 6A before a few years back but now the box seems fried. Doesn't...

Hey guys looking for some input on a 318 for an 84 ramcharger. The 360 I had rebuilt for it burned oil bad, the bores are out of round and the knurled valve guides are trashed. I have the old 318 and figuired it would be a good platform for a better build at a different machinist that won't...

So I plan on some RHS heads for my 360 but am wondering what compression ratio to run. With a tight .040 quench and shave .025 off the heads I could get 9.7:1 with my step dish pistons. If I leave the heads alone and run a safe .054 quench my ratio is 9:1. I could also mix it up and run anything...
