It sounds like to me you want the WOW factor when someone looks at the motor or the car and a blower will give you that, there is a Duster in town like that. If your car was going to run at the track only a 605 with two carbs on a good intake and lots of Compression and good gas and I would pick a Hogan intake can make you a ton of horse power for an easy 9 second pass. Most of the racers around me run NSS. All run in the 8s and some have run as low as 8.20 in a Super Stock A Body that came apart at just over 1100ft doing this. This car had the special set of Aluminum heads from FHO. I was wondering how much spring pressure are you going to run and what valves and what valve seats. Most of these guys have bigger that a 750 lift cam, all but one guy and he runs 890s with the lift you have. I was going to say you will have to check things on the motor each year but since it snows early were you are you will have all Winter to do that.
