Honestly I am over the chevy swap in bop cars. Its a two way street just like buick said if someone has a chevy with something else powered by a chevy ( Like a '69 Yenko Camaro with an all aluminum BBP & a five speed behind it ) most likely that person would be upset as well probably ready to shot me. I basically see the same answer's "its cheaper", "its better" same ole scenario. After awhile its get boring looking at the same engine transplant. However, bop parts are more & more available for those that lazy! Look in the back of Car Craft & Hot Rod mags in the ads you can see companies like TAPerformance ( Buick ) Rocket Racing Performance ( Oldsmobile ) and most definitely Butler Performance ( Pontiac ). See, its easy to follow a trend but it takes bollas & commitment to build a unique hot rod in a land of play-it-safers. I've been told by my cousins that I am an idiot because I plan on putting my 425 in my Cutlass. They're full blown chevy freaks & those are the same one's that compare chevy to every damn thing that deals with high performance & that's pretty ignorant imo. Chevy's are cheaper to build if its a small block but, if its a Duramax or a BBC then the price range is in the same neighborhood as any Big Block bop! Plus, why do y'all think GM turn into Government Motors? Some genius thought it was a good idea to put chevy engines into every other brand back in the 80's & that's when the downward spiral begun. Even when they came out with the brand new GTO's I knew that car was gonna pile up on car sale lots. A lot of real Pontiac supporters didn't buy into having their most know car with a chevy engine in it! That's like trying to fix something that wasn't broken lol! The GTO in '64 didn't have a chevy in it so what the hell made them think it was gonna fly with the Pontiac crowd? But, back on the topic I am over the whole crossbred ordeal, no disrespect, if you don't know anything about a Buick, Olds, or Pontiac ya got goole & bing nowadays its easy to take to easy way out. I hope that chevy powered bop better have a $hit load of nitrous & a lot of rpm's for my Olds when I am ready for it to prowl the streets lol!!
