This tale is for my 82 D150, bought as a dead dog and needing a new engine. Details are here:
Mission Creep on a D-150
Because I sometimes learn the hard way even though I do a lot of research and try hard not to screw up, we have this thread where I finally discovered I had too much timing and was detonating, which trashed my rod bearings.
Ideas on what's causing my click/tick/rattle noise?
As punishment for being a tuning goon, I got to pull the engine and tear it down to bare bones nothing. The crank was OK, the rods were OK, I got new rod bearings and main bearings and I'm on the way to put it back together again.
This is an ordinary driver truck. I will take it to the track for grins but it's for dump runs and so forth. I want it to be a solid runner that I can take anywhere. I put 700 miles on the fresh build before I pulled it. I was reasonably happy with how it ran. Engine details:
82 slant, freshly bored .030 over. It's a hydraulic head but I swapped out the innards for solid lifters and valve train gear.
Lean burn junk removed.
Cam is a 2106R from Oregon Cam Grinding. It is 214/210 @ .050, 444/434 lift, 108 LS on a 104 intake centerline.
Trans is an A833OD.
Gears are 3.55 but having run this thing a bit, I'm thinking I need to go with 3.91 to get the OD gear up in the power band better. It starts pulling at about 1600 and does well (by my limited experience) to about 3500 or so. I took it to 4500 a few times but that's not something that will happen often.
Tires are 29", 235/75R15 mud-and snows.
Ignition is a super six distributor with HEI conversion.
Intake is a Clifford 4-bbl with the water heat provision.
Carb is an Edelbrock AVS2 500.
Exhaust is Clifford shorties, 2-1/2" two-into-one all the way to the tailpipe through a Dynaflow Dynamax.
Head was shaved to get 7.6:1 dynamic compression.
So here's my question. If I want to change anything on the engine, now is the time. As mentioned above, I was fairly happy with how the truck ran in its original configuration. I have many options for intake, carb, and exhaust. What are recommendations for getting the most torque out of this engine? Other parts I have on hand:
Clifford adapter to run a 2-bbl on the current 4-bbl intake.
Offy 4-bbl intake.
Holley 390 4-bbl carb
Super Six intake with an almost new Carter BBD.
An old Offy 2x1 intake that was modified for 2x2, running dual Weber downdrafts.
Original cast iron exhaust manifold that was VERY nicely ported and gasket matched, the outlet was hogged out for a turbo but the heat stack was cut off so there would be no manifold heat.
Dutra Duals
Dual Dutra Duals
I'll be running this info on my two favorite sites, FABO and slantsix.org. Both have a tremendous number of slant gurus. What is your experience with any of the above parts, what would you recommend, and why?
TIA, and let the games begin!
