Well i picked up another gtp on the weekend. The block cracked on it causing the engine to cease. It has 147000kms(91000 miles) on it and is fully loaded. The heads and everything are fine. I was going to put the engine from the car i drive now in it cause the trans is going and it has over 332000 kms (206000 miles) on it. But then decided to build one for it. I want a n/a engine but am not sure what years and models have the 3.8 that will work in my car. I read the sticky in the n/a section but i am still unsure. So if i only need a short block, being block, crank, pistons, and rods, what engine years can i use. And from what car models, eg buick, bonnies. Hope that makes sense. I am only going for minor power gains, a 3.4/3.5 pulley, down pipe, intake, plugs, t-stat, ect, as it will be my daily driver.
