well, I just had a motor put in my car by a mechanic and well, I also threw a rod 4 days later...... Does any of the parts from a 2.3 block fit into a 2.7 block... The motor I had him build was 2.7 block, w/ a shrick cam and all the works. If the head is good, will I be able to use it on a 2.3 block...I pulled the 2.3 liter out because it smoked but, I need a car and the mechanic is trying to be a prick and not want anything to do w/ backing his service up...The worst thing is, he wrote on my bill of sale, NO WARRANTY..... I think he may have known something... well anyways, someone help me.... my 4 day motor cost me $3000......!!!!! thank you...:)
