trying to figure out HP??..and possible estimates on 1/4mile times
tentative specs on my build:

97 z28 A6
383 stroker
9.5:1 compression
Heads- 63cc chamber / 210cc intake
stock lt1 intake manifold portmatched and plenum increased
52mm tb (for now)..might go to 58 in future
Cam 224/236 .560/.571 114 LSA
meth injection
procharger: 12-14psi boost
LT Headers

 

Ill guess alot? Sounds like you picked the right parts, good boost friendly lsa, big heads, good compression, north of 600 is possible.
