anyone wanna guess what my 1/8 mile will be

I have a 71 dart no interior besides race seat. Its a 69 340 .30 over with flat top pistons and stock j heads. Has .484 purple shaft cam , headers into 2.5 inch exhaust with h pipe that dumps by rear seat. Has a 750 Holley vacuum secondaries and Edelbrock RPM Air Gap. Has ladder bars and 3.23 gears , also a 3k stall converter. Not my first time at track and I know the 3.23 are hurting but cant afford to change right now. I will probably run a 8 to 9 inch slick.. Im guessing 8.85 Im optimistic because car feels strong and I didnt build engine just going buy what owner said. He told me he ran 9.2 on street tires so... his 60 foot had to suck
