guessing 317@4900 for ported heads

i would say without spending over 40k on a drivetrain a realistic number would be 800whp with stock block and twin s366 or similar turbos. if a stock block is a must i would be more comfortble with 4.030x3.250 but like others said if you want 1600whp start by spending around 10-15 on a short

use the search function there are a few good threads on this casting. but i believe like melway said wack the huge guide down a bit, a good bowl blend and a quality valve job should get you 75% of the gains you would get from paying for a "full" porting job.. if that makes sence

i know you can get the comp "high-tech" in .080 or .105 which should be plenty strong and last, or if you wanna spend a little more and have peace of mind manley sells .120 wall 5/16 that i believe are called there "pro series" and should be a shelf item. in not sure if the weigh...
