i bought an engine from www.cobraengines.com
im very happy with it its beautiful and very strong
i got 355 hp fuel injected turnkey engine
so its got 24lb injectors e303 comp cam, e-brock intake, e-brock performer heads, 70mm throttlebody and i put on bbk ceramic headers 73mm c&j maf, a 3core aluminum radiator, and a shift kit in my aod. a b&m torque converter with 2000 stall, also flowmaster cat back. i ws wondering what kind of rwhp i am running?? if the enige is 355hp from the builder. they real do a nice job i had a engine builder/mechanic install it and he loved thier work. im planning on putting the gears but cant figure out from forum what gears 3.55 or 3.73? i plan on next spring putting on a supercharger. but not sure yet, also is the e303 cam work good with superchargers?

to calculate your D/T losses the standard rule of thumb is 15% for automatics and 10% for manual transmissions. For an AOD, i'd use more like 20% to be honest and that would give you a RWHP (from your 355HP @ the Fly wheel) down to 295 or so at the wheels.

The E cam is commonly refered to as the blower cam. If you really want to super charge your motor then stick with a lower gear. That will be up to you, depending on the amount of highway time you see and the amount of track time your car will see...

Ecam and auto...not the greatest pair..pick a low gear because your going to be really soft down low with that cam.

E cam is a decent cam..but 20yr old technology..if I was going to run your combo with a blower the Ecam combined with an auto would not be my first choice. As for gear selection..if your going to slap on a blower I'd not go any lower than 3.73 or maybe even 3.55..if running N/A I'd look at the 4.10.

i believe ill be going with the 3.73 with my setup and see how i like it then this spring put on the supercharger and i should be able to run decent. its only a daily driver that i like to get down on on the street work is only 2 miles or so away
and i drive on highway but not too much
