    SP75 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Sp-75 I have had this engine in my 2000 Camaro for about 500 miles. So far it seems to be a good purchase. Good power with ported 799’s, tsp v4 cam, fast 92mm and full exhaust. Still in break in period but power is there! I looked the motor over when I got it appears to have been put together well.

    How much power can this motor handle?

    Asked by: Jerry
    Hello Jerry, there are too many variables to determine that. We have had customers making upwards of 800HP with them from what we hear.

    I am working this short block for a 2002 Camaro SS. Do I need to drill and tap any holes in the front of my AC and accessories ?

    Asked by: Desmatess64
    Yes you will. These use the truck block, so the provisions are not there. There are template kits you can purchase to make it a simple process.
