new dyno and track times (cc503) I have been to the track quite a few times lately and the car kept getting faster so i decided to dyno it also
the car is a stock headed 355, stock compression with a 503 cam with full bolt ons
there is only and 1/8 mile track around but the car went
on motor: 7.79 at 93 mph with a 1.8 60'
on spray(125 shot): 7.32 at 102 mph with a 1.78 60'
here are the dynos

its a 6speed swap car, best it would ever do on motor with the a4 was 8.3 at 87 but im still running the stock clutch as of now.
Over the past 3 months of just driving the car it had gotten faster, I had it dynoed right after i did the swap and it only made 351 hp which i considered about right. Now i havent changed a single thing since and it picked up 20hp but it runs like it did also. I personaly think its pretty high for a 503 cammed car but idk
thanks for the compliments

I'm not surprised of those #s, it has been freshened, most likely had good machine work, rings/pistons were set up right, i'm sure that extra 20 hp came from the rings sealing after break-in, plus i'm sure its been tuned, so that helps, yeah MOST will make 350-ish, but alot of them aren't freshened, you went .030" over, that 5 cubic inch is worth about 5 hp. The car is running really strong on that 125 shot, you must of been having traction issues to only get a 7.3, with that 102 MPH, thats solid 6.8 runs, now start working on the suspention to hold that 500+ ft.lb torque, i'll bet that car will go low 10s on a solid N2o run.
So whats the complete run-down of all the engine parts if i may ask???
