Olds Chevy engine swap exhaust cc2 headers
First, to the Negative Neds out there, it IS just a car...(PS my daily driver is an S500) and I'm swapping an aged 180hp motor with 180k miles and a maze of sensors and electronics for a simple one with nearly double the hp, which I picked up for the meager sum of $1500. BTW, the motor and trans and all parts attached are for sale for the interested.
I too am engaged in an engine swap. Putting a ZZZ crate motor chevy 350 (340hp with 380 ft.lb torque) and TH 350 trans. into a 1975 450 SLC. So far, I've got motor mounts and trans in, and have used an oil pan and pump set up from an old Nova / chevy II (ChevyIIonly.com). I had to modify the pan some, and use long pickup tube, but only had to pay $150 and some welding time. To get trans to fit, I cut the "ears" off the housing that hold the lower cover. The motor seems to want to be offset 1" to passenger side, to line up with pinion and clear the steering box. I shaved 1/8" off oil filter area of block and 1/16" off steering box to get better clearance. I am planning to get the Sanderson CC-2 headers, they seem to be the only ones that will clear the MB motor mount area. Planning to use MB alternator and PS pump, as well as MB radiator fan shroud and fan! (bolts right onto chevy water pump!)
Does anyone know if a lower rear gear (such as 3.75) can be swapped into the W107 chassis, currently running 3.07 rear gear.
The weight of the chevy engine/trans combo is probably 100lbs. less than the MB drivetrain, and I'm hoping ride height will be undisturbed.
For driveline, planning to use chevy yoke and shaft, and have a shop put the MB propshaft end at rear, and use MB flexdisk and rear end.
Any other assistance from experienced swappers is welcome!
