And who is the best tobget a mail order tune through? Any help will be appreciated. Thanks guys.

Do you have a build thread on your Nova?

Realistically they are 340-350 hp bone stock, so with tune and cat delete maybe 360 hp

look for a l33 bit more compression (10:1) and aluminum block be perfect for your early 60's nova. Headers will help if you want more power than stock. I think should easily get 350hp -360hp doing nothing.. Headers and nice xpipe high flow exhaust will get you even more.

If you cam the engine... even more.

Here is an interesting article with a 5.3 and different cams

look on last page of article for some aftermarket cams. I personally like the one that made 411hp #6000rpm or the hottest cam that mad 442hp @ 6200 rpm. Would make that light little nova move!
