It's gonna be in a dragster at 1955 lbs... The same motor in the car now with the 572-13 heads goes 4.60s but i want to keep him in the 5.00 flat range.. If i can get by using this short block i will build me another one that would be more nitrous friendly... Just figured if i was gonna have to build another short block i would rather use the money to build a bigger one than a smaller one..

My 572 daytona 4.500 stroke 4.500 bore ran 5.48 in the summer heat running a set of 440-1 heads that I ported at 2425#. My combo was found to have a bad brand new Barry Grant fuel pump, a cam that was really made for my B1 heads, and almost pump gas compression. Next time out it will have B1 heads on it. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

I have a customer with a 550" and SRs ( PRH) that has run 5 teens in a dragster with what I'll call " not superior" tuning skills...lol 557 in a foot brake door car that runs 8.90-9.00 quarter at 3200# with OLD OLD -1's and old style chamber. 1050 DOM, single Indy intake. Bunch of cars that run low 9's on -1s, all 3000-3300#. Havent run 345CNC in a dragster,but I think like John says, should be an easy goal for you. Good luck to junior..
