Damm that’s a bad ass motor my friend ya I was gonna get the 4.9 but ended up just getting the black 4.7 either way these things build crazy psi hahaWell I ordered the blue & brown PCV valves that I saw in another thread called out for the GT500s. I gather blue was stock & brown folks swapped to as an "upgrade". Cheap enough I ordered both.
JLP built my motor. It's a darton wet sleeved 3.7 big bore GT supercar block, MPR did the sleeves, JLP did the longblock & his CNC profile on my GT supercar heads. I had a 4.7 KB that I picked up barely used, but I changed my mind from polished, I was going to buy a black 4.7, but saw they now offered the 4.9, so I bought a black 4.9 instead and sold my polished 4.7 lol
