It's been a while, but the instructions say something like taking it one turn, then take it to 6 o'clock or something. I only took it to 6 o'clock. There's a flat spot on the cams, I rolled the engine back over, then re-timed it. I wish I could be more help, but it's been almost 3 years.
Well I got good news. Machinist called me this morning. Block _will_ clean up at .005". So gonna send it. Will have stock crank, Molnar Power Adder Rods and Diamond Mod2k pistons. I can tell you, it's definitely cheaper to use a Gen 3 block than what I have in machine work. Live in and learn...
I don't know about the Vortech, but for my Whipple this is what I got from Dustin
5000' - 6000' .25 - .375 smaller
LT's .5 - 1.0 less boost
Max Diameter Pump Gas (93) 3.25" @ altitude
I'd hope whoever you bought the kit from would offer some guidance. If not, pick another dealer. Just my $.02...
