Manual Transmission power lose

[whoboy580]

Let me first start off by saying I am sorry if this is a stupid question. Now with that said. I just got done building my 383 stroker. Its complete forged rotating assembly Brand new internal balance. 10.3:1 compression, I bought a Trick Flow 490 HP Super 23 Top-End Engine Kit (TFS-K314-490-440). I followed what they said they used for a intake(Victor Jr) and carb(holley 750 DP) it states you will have 490 Hp. I know you cant believe that but I should be close to that. Now I have Hayes Flywheel and PowerGrip Clutch. My rear end is a built 10 bolt that has been in the 10's with another car. My trans is a stock t5 that came with the car. I know the factory never put t5 behind 350.

Now here my question. I took the car to the track friday for the first time ever. I ran 13.8 at 103 with a 2.091 60ft, I was pretty upset figured i be in the high 11's to mid 12's. Now I know there a 18% Power lost to the wheels with a manual trans which should leave me around 400hp to wheels. Now I ran those number thru and engine calucator and it says i am only make 280-290 hp to the wheels. Can a stock t5 hold the motor back that much? Please help

all depends what gears are in the trans and what gear is in your rear if the 2 are working together,also what size tires are you running at what psi?

Its just stock t5 trans, I am not sure what gears come in the trans. I have 4.10 in the rear posi. I am ran with stock camaro 16 inch wheels with 40psi.

you can have 1000+hp in your car but you aint gonna go anywhere with stock street tires,spin alot off the line?
