Hi J par!!! Oh, where do you get an al motor??? lol ..... Anyways, I agree the LA is an excellent choice, just installed one in one of my dusters. BUT.... You still may have to change the Oil Pan if it's a truck motor. If it's a 2bbl, probably still going to change the intake. Your still going to want to install a new timing chain (which requires the removal of the timing chain cover). So really, not really much extra work for the magnum. Just the locating of the LA timing cover which is no big deal.
