The Shelby dak uses a 4 speed auto, that was a light weight 3.9 TBI
unit that dies quickly with any power to it, the later 518 didn't exist yet. So to have a 360 and the right trans would mean a 727 3 speed.
The Shelby Dak used a Diplomat 318 oil pan and pick up and the car exhaust manifolds, lastly it got a one ton dual snorkel air cleaner for the other 5 HP over the 88 318 from a D150.
I have done a 360 swap, the oil pan hits. So a sledge hammer is needed lol. BTW for those that don't know the engine mounts are different as well between the 318 and 360 like the oil pans.
What could the truck got with very little effort? The Shelby Dak could have had an Edelbrock Performer EGR
intake with a 360 TBI
. A lot more air and less weight, all on top end which shouldn't have murdered the trans. Then the Edelbrock was an emission legal intake in CA with the EGR
The fools moved the engine and trany back an inch and a half and didn't shorten the drive shaft. When they squat they impact the rear end pinion bearing.
Also the 360 TBI
intake bolts right on and the larger 360 TBI
uses the same injectors. MP dropped the factory cal and the one they sold for a while was the MP cal under the stock part number.
I rebuilt a TBI
engine with the 9+ compression pistons and a .450" Custom Delta roller cam. The truck ran night and day better with the 360. Also the truck got poly and KYB gas adjust shocks with Eibach Pro kit springs with 2" lowering blocks to sit level. Night and day better handling, didn't lower the truck past stock. Stock they got V6 springs that crushed for an inch lower height, Eibachs your right there but stiff.
Big issue with Shelby Dak owners, you can buy a new computer. You can use a pick up computer either as they didn't have a tach or electric fans. There is a local place here though that'll rebuild the stock fans. Either shel-game or FWDperformace needs to get a MP cal and swipe the vin so that SOMEBODY can sell Shelby Dak people a computer. Also the rev limiter is crazy low and even with a better engine they don't rev past about 5100 RPM.
Loved mine but my dad let "jack" drive it, he rear ended my 93 Cummins W250 going 35 MPH. The 16K pintle and 15k class 5 raped the truck and it's frame to death. Hope to get another someday. There is a time and place for a 4 banger, a Shelby Rampage, not a heavy Dak. They should have built a new roller cam 340 block for the truck with 360 top end. The HP without the torque and the oil pan works and the trany lives, not to mention a new 340 block that doesn't cost $2800.... Bringing back the 340, even with less power would have been a massive hit with the old MP crowd.
