OK,I know nothing about LS as it an't mopar, other my son is using one in my 47 Chev he is restoring, it was one that was rebuilt and sitting.
He is also using the trans that came with the motor.
the only computer he will have to worry about the one he install in the original factory radio.
I presume there is something on the LS motor?
The other day he wanted to put power steering on his daily driver that was Dad's 53 IHC short box 1/2t. He had changed the rear end to better hiway gears.
Was going to update the front end, but needed a ps pump and box.
He spotted one on a rebuilt 454 sitting in the corner of his shop for a while,
So wth, out with the straight 6 and in with the 454.
think he is still waiting for a new front axle setup. Mustang
