I have been thinking about a forged 5.3 or 5.7 build... thinking 11:1 cr should be nice.

2 weeks ago with my 222/224 cam I was running 8.5s w/ 1.96 60ft

, with the 214/220 cam i am running 8.35 w/ 1.83 60ft... Not to mention my shift points moved up ~300rpm...

depending on what fuel you are running, i generally ran 27-28* in mine..with 93 octane. it one of those things that are hard to tell, if you arent dyno tuning it. there is a fine line where increasing timing can decrease hp levels, i think around 28 was the sweet spot for mine... anymore lost about 4-5 hp. i would think yours could stand that or more, being that you have a better intake mani and heads than i had.

Shift kit, servos and the accumulator thing....

Yep I am thinking about giving Chase (Built408) a PM on getting the trans built. These 7k shift points are not going to make my tranny last long

I might go back to the dyno, last weeks dyno session was a huge cluster ****... I think my trans and/or verter hates me.
