Thoughts on the stock 402?

[GMCPaul]

A example of stock form 402 performance is we used my wife's 1971 GMC Suburban 3/4 ton 2 wheel drive with 402 and Dana Posi 4:54 rear end as one of our vehicles pulling 1 of our trailers behind it to go to Carlisle 2 years running and it pulled a 12,000lbs load both years through the mountains running 70-75mph the majority of time and we had the A/C on non-stop in 95-100 temps outside. There were 2 sections in the mountain that had such steep long grades we did get slowed to 55-60 on but other than that no issues doing it.
So stock form there strong but they also can definitely have performance boosted.
