Talk me into or out of Holley Terminator X
I just did the full deal Sniper deal and I love it (but, I wish I would have gone Terminator X). Power gains aside, I like that the car can sit for 3 months and I can touch the key and it fires, high idles until warm. I can drive it dead cold like a modern car. Tuning come from a lap top so not more pulling the distributor and f'ing with spring and slots, pulling the carb and trying these jets, this shooter, that pump cam, and getting to deal with spilling fuel.
But, it all depends on what you want and are used to tuning. Some don't mind dealing with the above and if your all dialed in then HP gains may not be something you get.
