the car made-
312.5 hp,283 torque

with cut out open.
car made
326 hp,296torque

this was also done on a chasis dyno.

Do those numbers sound about right?
all i have done to this car was a cut out, remove cat put in resenator..Figured it might be just really restricted..

EDIT= also says car is runing base tune, will i see a crazy difference with a more aggressive tune? pulls were done up to 5800 and still kept gaining power, but i didnt wanna risk going higher.

 

Houston, we have a problem! No those #s don't sound right. Did you just buy this car?

 

those numbers are f'd if that has a 383 in it.

 

I agree those # are off but you should probably be running a mild or better tune. Also you could run 37 or more pound injectors and a 58mm throttle body to help.

 

bought the car about 4 months ago,i guess we'll see how much i actually gain from a tune.is the automatic trany really hurting me? snce i've heard they suck in a good amount of power?

 

What "long tube" headers does Edelbrock make?

Was the LT4 intake machined properly to eliminate the interference with the valve cover rail on the LT1 heads?

What is the flow on the heads?

What do you mean by "base tune"? Do you mean "stock"?
