When I backhalved my car the 1st pass was in the 6.80's @ 102.xx, got it down to 6.69 @ 103.xx best. Same thing when I swapped out the 357 SBC for a 511 BBC and also changed over to R & P steering at the same time ... balls out on the first pass

Neighbors Dragsters we built from scratch, 1st one ever for either of us and it went 5.14 on its very first pass w/ a 496 and it went as fast as 7.40's 1/4. It also won 2500 $ on its first night out

2nd car we built went in the 7.10's on motor only on the first pass and best a pass of 6.68 @ 202.xx on 2 systems and won Best Engineered car at a Milan Mich. IHRA Divisional race. And got the R/U position at an IHRA Nat Event in Grand Bend.

Do you trust your work or not ?

Have you previously gone as fast as you expect the car to run ?
