Scottie-GNZ Posted November 3, 2001 Share Posted November 3, 2001 Anyone looking to do a high HP NA V-6 has several options, but if you are serious about approaching 400hp, you really only have 2 choices, the 4.3L Chevy or the Buick 3.8. Both base production engines would require extensive internal work to hold together with that much HP. Luckily, Buick produced such and engine that could be purchased from their catalog. This engine is referred to as the Stage II and is the engine that dominated Busch GN before they abondoned V-6s. It is also the same engine that is (was) used in the Indy Lights and produced 465RWHP. In turbocharged form, it was used in Indy cars and usually took the pole for the Indy 500 and of course the fast drag racing Buicks are pulling 1000+hp in street-driven cars. There is currently a Busch GN engine for sale and if anyone is really serious, DO NOT HESITATE. http://www.turbobuicks.com/ubb/Forum11/HTML/000729.html There is no way in hell anyone can duplicate that HP potential for $3000.
