i've got an awful feeling that i've shipped the wrong electronic conversion over from summit racing.
i ordered a B engine one but after reading this and that i think i should have got the RB one for my 440.
can someone please let me know.
Yep, B is 383/400, RB is 426/440. You can buy an adaptor to convert a 440 to 383 use, but I think you're scuppered as the shaft ain't long enough to reach the drive.
