89' E150 EFI Conversion Upgrade
I have an 89' E150, 351w EFI. C-6 Trans, completely stock w/ 115,000 miles on her. I would like to get more horseporwer/torque from it. Ive ran into problems finding parts that fit because its a van. Can anyone tel me some good setups that would fit her. Money is not an issue and i would like to keep gas milage reasonable, but no big deal. Primarily use it for towing. Thx all

I swapped in a 351 when I wasted my 302. It did a nice job of improving my towing. In hind sight, I should have done some cam and head stuff along with the truck 351 efi upper/lower intake I installed. A properly matched cam would do wonders.
I've thought about a supercharger......

For towing you might want to consider lower gears in the rear diff.
They will give you lots of "bang for the buck", especially when towing.
With a C6 you dont want to go too low though or you'll be revving quite high on the hiway.
Unless you convert the Speed Density EEC system to a Mass Air Flow system you have to be careful with a different cam or the PCM will get confused and it wont run well. Been there done that.
