HEI with Howell EFI Info
the howell kit was a direct bolt on. since i bypassed the computer when i installed the HEI, i didn't need to perform that part of the Howell installation. the howell kit doesn't control timing so nothing needs to be modified as far as the distributor goes. only need to tap into the Tach signal out of the HEI for the computer.
ordering from howell i think is a bit cheaper which is why i did it.
hope that helps...
