Quote from: LTZ C20 on May 12, 2015, 02:22:27 AMThe cam timing is off....For zero advance, the crank gear is installed properly. BUT, the zero timing mark at the outer circumference of the crank gear should align with the timing mark on the cam gear. With the timing marks aligned, the crankshaft key should be at the 2 o'clock position.
Incidentally, consider installing a cam bolt lock plate. And, apply red Loctite to the cam bolts at final assembly.

Isn't anywhere near close for an OE roller cam. I didn't even choose the 1 I bought, 1 of the summit guys recommended, I told him it was for an OE roller, he said his info said it would fit, yet last night it was no where near close. So I called summit and a different guy said that since the OE rollers use a thrust plate behind the gear that a lock plate on the outside face of the cam gear is not needed. The outside lock plate is for when an engine isn't using a thrust plate, such as a flat tappet cam. I'm going to call their tech department back again today though to be double sure. Also, I did use loctite.
All but the endmost intake manifold bolt holes open into the valley and are exposed to oil splash. All of the head bolt holes open into the block water jackets and are exposed to coolant. Chase all of the bolt hole threads then rinse them thoroughly with Berryman's B12 or similar - blow dry with compressed air. If reusing head bolts DO NOT chase the bolt threads - use a wire wheel instead - even better, use new ARP bolts. Apply ARP PTFE Thread Sealant, P/N 100-9904 to all of the bolt threads and under the bolt heads.
