Dave likes nitrous and was looking for a 5.0 bore space motor for a while. With all the other cars having big motors, he was having to lean on the 632 HARD to keep up. For what THEY do, the Pro-Charger motor will be fine. I am sure most if not all of the parts for this new build are donated, where as he was looking to buy a nitrous motor. So give it a shot. I suspect he is STILL looking to buy a bigger nitrous motor though and that will likely be back in the rails

A 632 nitrous motor in a car that weight, a low 4.40 or high 4.30 is a great pass using a LOT of nitrous. A 5.0 motor in that same car will run those numbers with a fairly small nitrous load.
