I have a 68 Cuda 4 speed I am building , its a driver mild build
What do you guys think of the Torque storm unit , thinking of 5 psi boost tops 450 hp
drive it on the highway , take a trips kind of car .
I have fire breathing N/A dragons and all the issues that come with driving them long distance or getting stuck in traffic and having to idle for long periods , but looking to build a driver this time, fun
