the "B" guys have it......

I guess I would differ that 10's is the "easy button". Been going to the strip for 30+ years, and I can tell ya, 10 second B-body street cars didn't roll in and out like a Walmart parking lot. But yes, the fitment is better and headers are cheaper than A bodies for sure.
Easy if you have a lot of tire, correct pinion angle, long shocks, adj snubber, 800 dollar+ convertor, and really.. a tame existing motor of common power around 375-400hp..like 60% 'these days' of what people have.

If all that is done at a shop.. ..hmm cut n roll of the rear is around 250.00, separate the trans for the convertor, valve body install, parts n labor $3000+ or so plus whatever else.

Do it yourself, and you'll save 1500 maybe...but of course youve already bought more in tools to perform the task.
Talk is talk, it's still work.. people are always quick to surpass a goal and then say 'that was easy'
