Street/Strip Series 383 Long Block

Our Street-Strip Series 383 long block is not to be confused with the ole, ever popular 383’s of the past.  This modernized 383 will blow the minds of some old timers that like to reminisce about the old days and their mouse motor strokers.  We take a standard 5.3 truck motor and transform it into a very capable package.  Whether you want the fastest Silverado in your neck of the woods or looking to power that muscle car undertaking an LS swap, this is a package worth considering. 

Plan to clear 600HP NA with the right cam and intake selection!  This package is still dependable at the 1000HP mark if you want to put a little extra squeeze on it with your choice of power adder
