what would make more power a 6.2 n/a or a cummins 4bt im assuming the 4bt would use less fuel

not to sure 6.2 v8 vs 3.9 4 cyl

Stock, I'm not sure BUT there have been some to take the 4bt well into the 300rwhp range while maintaining longevity and I'm pretty sure there aren't that many (if any) 6.2s at that power level that are going to have the longevity of the 4bt.

Remember just about anything that can be done to a Dodge Cummins 6bt can be done to one of those 4bt's. Injectors, turbos, GSK, DV, etc.

C-ya

do a search on this . 4bt cummins. tons of ideas, im all in favor of doing one for a driver.

I'm thinkin' the 4bt would be more powerful.
