My dad got a 93 Lightning, the original in it 351 was bad, so instead of dumping money into it we got a 351 w roller cam motor from a 97 f250 with low miles, and installed his gt40 heads and intake on it. How much better do you think it will run compared to the stock 351 with the flat tappet cam??? We didn't finish it up yet, still need to button up a few things.
