Best Performance Upgrades for Little Money - Here's My Vote

Agree, and I see a lot of this around the roundy round tracks of late. The SBM engines lasting 3 years and the chevy teams spend 12 to 30 grand a year..

I wonder if this might be due to the cheap prices though?
if I can build an engine for 500 dollars I might try it myself, but if it will cost 2500 I might have a professional do it
so the cheap entry cost of a chebby attracts a lot of back yard mechanics, while the higher initial cost of a mopar get more professionals wrenching on them?
