Got on a Dyno-Jet today. It was a blast. After the first run I was shaking like the first time at the drag strip. Dyno numbers make more sense to me now. Here's what I got:
Motor run-341hp@5800rpm, 348ftlb@4300rpm
Nos run (150hp)-463hp@5500rpm, 516ftlb@3600rpm
What do you think? BH

What ONE mod would you say accounts for most of the muscle
That one mod would be heads/cam/headers. They all work with each other to make more power than the sum of all the individual parts.
I know that can sound confusing but consider this. Headers on a stock car might make a 10 hp difference. Headers on a car that already has a cam might make a 15-20 difference. Headers on a car that already had a cam and heads could easily make a 30 hp difference.
Same goes for heads, fancy heads with a stock cam and headers might not do too much. Sure it'll help some but you never really see the true benefit until you do it all.
When I did a cam swap on my car I picked up 44 hp. Since the rest of it was stock that would be a cut and dry fact that the cam gave me 44. Then I added headers and picked up 23 more. How much of it was from the headers though and how much of it was for allowing the cam to function better?
It's a really tricky thing and it makes it impossible to always accurately predict the gains any given mod may do. When somebody is asking how much horsepower mod X will give you have to ask another question. Who knows, do you already have mdos Y & Z?
Just my $.02
IMHO on my car the best seat of the pants improvement came from the headers. Unfortunately though since I installed the headers after I did my cam I don't know if the headers would have the same affect on a stock car.
