SO....heads and intake are 90% of the power. Plus if they really answered your question then they couldn't charge $5000 for a set of stocker heads and $1800 for an intake lol

What percentage of ET do you think is attributed to, suspension, shocks, weight distribution, transmission and overall set up of chassis?
