I'm talking about a NA 6.4 Hemi, like in a Scat Pak. They have about 550 gross hp as sitting box-stock. Just a cam upgrade and headers and they go over 600+ HP. Put that in a 3000 lbs Duster backed by a 904 and a quality converter and see what it runs. I'm talk'n 600 hp the cheapest, and reliable way that drives great on the streets.

Why use a 904???? Since the Gen 3 (can't actually) dominate at any racing class why wouldn't you use the mating trans that these modern (I wish I was) marvels come with? Exactly!!!! WEIGHT!!! Everything about a Gen 3 Hemi is a PIG and part of why it is slow and also find 1, JUST 1, heads up racing class N/A that a Gen 3 Hemi is at the top.......I will wait....
