Interesting how inefficient carbs are compared to fuel injection. Scott, is your 390 stock in all other respects? Doug
No, not really stock Doug (OK, not at all). I rebuilt it about 1982. At 90K it was burning oil and always pinged real bad. If I tried to drive it very far the lifters would go flat.
To fix the pinging I lowered the compression using 8,5:1 forged aluminum turbo pistons. At that time I also installed an Iskedarian cam - which fell apart about 10K later! I stuck with stock heads at that time.
So at that point I gave it a light rebuild with new bearings, cam, etc.
I've done further mods over the years.
Presently it has:
Edelbrock Performer cam (Not the RPM model)
Edelbrock intake (again, not the RPM version), lifters, timing chain and 72cc heads.
Ford Duraspark distributor driven by MSD 6AL capacitive discharge ign control system with MSD epoxy filled coil.
1,76 ratio aluminum roller rockers and hardened shaft assemblies (forget what brand)
Power Force Harmoic balancer
Balanced rotating assy.
High volume oil pump driven by Ford Racing chrome molly drive shaft
Bone stock, all stainless steel exhaust with all resonators and mufflers
"Tuff Stuff" brand 100A alt. and high flow alum. water pump. (Alt upgrade required for increase electrical load of EFI & fan)
Deraile 2 speed, 18" electric fan controlled by EFI - Still need to see how this works out..
If it were easy, I would changed out the cam for a roller model. I've also considered FPA headers but I really don't want that header "sound".
Outwardly the car looks and (mostly) sounds completely stock
