Not Ranked
Excaliber, reading the ad, I don't think it has been sleeved down to a 390. I think it has been bored to 428 specs. So you end up with a short stroke 428 so it should rev better than a 428. I think that is what he means.
Westcott, I would want to see good photos of the heads and crank prior to doing anything with this. It should be a good preformer. Jim
