Ok boys. Round 2 has commenced. Some updates first. On our original dyno run we had that flat spot that came in around 5200 and just killed power. We ran it for the season and then did some investigating after we repulled them. Turns out the ******* that did my cylinder heads did not shim the valve springs. Some (alot) of the seat pressure were in the 120 range. Can we say unstable? Now for the good stuff. While I have the heads off we are upgrading the lifters from ls7 to johnson short travel linkbars and manton 3/8 .130 custom pushrods, titanium retainers, and possibly yella terras in same ratio. The heads will be getting kissed to push compression from 10.6 to 11 and head porting will also be taking place. The shop doing the heads is claiming 360 cfm compared to 320 stock and only going up 10cc on port volume. Other minor details will be putting the std pressure oil spring in to reduce oil pressure from current 100. Dyno in month month and halfish. Place your bets. Here is previous dyno chart for reference

Slight change of plans. Ordered some zl1 superchargers, holley terminator efi, and having chambers on heads softened as well as everything previously listed. Aiming for 8psi to keep it simple.

You may be correct but the stock springs are 120 and they can not control anything more aggressive than a stock cam for the most part. I personally believe its low for these heavy 2.165 valves. Now that the blowers are going on I definitely need to get the ducks in a row.
