The big block Buick aftermarket is extremely limited and the parts available can only take you so far so I went the LS route. Going that fast with the V6 comes with a price paid in reliability. Awesome engines and they will always be my first love but time moves on.
I'm sure there will be plenty of purists and VIN sniffers that will hate on me and have nothing good to say about my car when completed. All I can say to them is "embrace it or chase it". Love 'em or hate 'em, the LS engines are simply awesome.:biggrin:
There is life outside of the Buick community.
I agree with you...

My friend Martin ("MAXSIX") just went to see Bobby at RPE his weekend to bring him his engine for some work, and he was telling me about a conversation he had with Bobby about LS engines...Bobby was saying that the Buick V6 will eventually reach it's performance limits and that you can only get "so far" with it and that's it...
Well, I can't say that I disagree...Even if there are numerous 8 and 7 sec turbo V6's out there, they are only a handfull and there'll come a time where the performance level will hit a certain "ceiling", and no matter what the racers will do to them, they won't go any faster, like if all the power available had been squeezed out of the Buick V6 configuration and unfortunately there won't possibly be anymore to squeeze out, and that will be as far as you'll be able to go with that engine. :redface:
That's why Bobby was saying to Martin that when properly prepared, an LS1 motor will run in the 8's and even faster with a lot more potential left, be a lot more reliable, unlike the Buick V6 which if often on the verge of blowing up, and that if he was to build a fast car for himself, he'd chose an LS1 over a turbo V6 Buick anyday...Funny to hear that coming out of the mouth of one of the best turbo Buick engine builders!

...but I understand what he means and to me, it makes sense. :wink: If I had a regular Regal, I wouldn't hesitate to swap the turbo V6 for an LS1 powerplant!...but not in a true GN though...
