    OK, the carb. might be a little small. Do you have any idea what cam is in the engine??? Knowing that would help us. It might be set up as a highway demon, and you might not know it. What I'm getting at is my car has a 3:23 rear, but the power band in my cam is 2500 RPM and beyond. That means after 55 MPH, my car takes off like a bat out of you know where.  :ylsuper:

    no... im not sure about the cam... but i can find out this weekend when my dad gets home

    im still learning about these cars... my dad went to a votec to be a mechanic, and he worked in garages for lots of years, but he is only home on the weekends, so im trying to learn as much as i can on my own

    i love working on them... i just dont exactly no how  :lol2:        also, if anyone knows any good books or movies that teach you about mechanic work, please let me know


    thanks,
    shane

    Heads, intake, Cam , exhaust & yes the carb is small make the biggest differences in power out put
    3 times now I have proven that a worked 440 will gain 60 RWHP going from a 850 carb to a 1050 Dominator

    I would suggest an X pipe into your 2.5 in exhaust. You would be amazed at the power and driveability increase. It shouldn't cost that much to put in line with the existing system you have.

     A quick one shot power increase would be to gear it up.  Go from a 3.23 up to a 3.91.  It wouldn't burn any more fuel than a batch of engine mods, and your would be able to feel the difference.  Just a thought....   :cooldancing:  ...................Oldschool

    Your engine sounds a lot like mine  build wise so I am going to make a few suggestions.
    750 cfm carb sounds to lite for that setup , I am running a 750 but am going to try a 850 to see if it breathes better
    3.23 open rear , as  Oldschool said a bigger gear will help a lot , I am running a 3.55 , would like to go to a 3.73 or 3.91  also a suregrip will help, I have an open right now and have to pedal it off the line
    last, I have a B&M Quicksilver ratchet shifter and I hate it . I have a Slapstick to go in the car, I never did like any of the cable shifters. Just my  :2cents:
