Hello everybody, i'm knew to the forum. my friends 02 grand caravan got run low on oil and know i believe it had a wrist pin knocking its a 3.8. and everybody around here is very proud of the 3.3 3.8 engine. i have a 00 3.3 sitting in my shop and i noticed that the cylinder heads are different and was wondering if i can put the heads off the 3.8 on the 3.3 and maybe switch the push rods. any advice is greatly appreciated, Thanks everybody.
