500 STROKER DETUNING FOR STREET/ SPECS AND ? - 02/16/12 12:36 AM
OK, some on here replied to my original post about rebuilding my 383 out of my 63 Polara 500 vert. I then decided to detune a 500 stroker that I have never used for a drag cuda that I have since sold as I wont be racing due to time and recent events in my life.
That said I have a 500 stroker sitting here that should have originally been at over 600HP.
I now want to detune it in order to use it on the street.
I found the cam card and some specs and want opinions.
My engine builder had me find the paperwork so he knew what direction to go, but had previously stated a new cam, springs and dueal plane manifold?
He also stated that (MAYBE) I should just sell the race engine and build two good driving engines for the street.
In any case, I am no engine builder and am looking for ideas. I just want to build a reliable vert driver that has some decent HP.
My builder has given me both advise on a different solid lifter cam and hydraulic? what do you think is best.
Here is what it is and some of the guts.
