i had one. never again. funny when they first designed these engines in like 91 they didnt have a trans strong enough to hold the engine. they cut power back so the trans would hold up. i know the valves are made of sumthing special and they are lightweight. i also kno this is a non interference engine. they have a great oiling system. also there is a timming belt. i dont like replacing the altenater on these its at the bottom in the rear on the pass side...... i have a supercharged 3800 now and i would not do anything with a dohc 3400 except a boat anchor. sorry my opinion.
