I am running a Chev 406 small block I purchased from Motor Works. It runs 437 hp at 5299 rpm and 462 ft lbs of torque at 3400 rpm. It is a 2.1 belt drive. I would like to add mulitport fuel injection. There are a lot of choices out there. If anyone has any recommendations or experience with this subject it would greatly appreciated.Thanks for any help you can give. Love this site.
