Ported IH, non-ported IH.. have some questions

[-=Jeff=-]

let's for a moment assume we have ONE specific LT5 that these scenarios would be on, Same conditions for each dyno run.. for the discussion it will be a n early model, 90-92 all should be relatively the same. Now within my scenario my HP numbers might be off but this is just a discussion (bench racing if you will)

Okay lets begin..

Scenario 1:
Stock LT5, Stock Exhaust
Assume 350RWHP (karterdon's Z has these #s)

Scenario 2:
Stock LT5, Headers and B&B with X-pipe

Scenario 3:
36mm Ported IH and Plenum, Stock Exhaust

Scenario 4:
36mm Ported IH and Plenum, Headers with B&B and X-pipe

Scenario 5:
Late model IH and Plenum, Stock Exhaust

Scenario 6:
Late model IH and Plenum, Headers with B&B and X-pipe

Scenario 7:
36mm Late Model Ported IH and Plenum, Stock Exhaust

Scenario 8:
36mm Late Model Ported IH and Plenum, Headers with B&B and X-pipe

Not sure how much the ported TB will truly give for #s.. for now assume the Stock TB,

SO what would each dyno at, going by the 350 RWHP of Scenario 1

I am curious what gains are had by what..

Discuss....
