What was the worst egine ever made?

I wanna know I think it was the 4G63!

any american v-8 from the mid 70's to early 80's. after the gas crisis there was so much smog eqipment and high economy tuning added to american cars that it drained all the power. a corvette in 1969 made over 430 HP and in the 70's with the same displacement big block v-8 made barely 220 HP. They even had the nerve to put in a v-6 one year.

4g63 the worst? are you nuts lol it was one of the strongest 4cyl ever made

Just stop talking you know what I do for a living so you know I know what I am talking about and you sir are wrong 4g63 is the biggest pos ever made especially the 7 bold obd2 engine

well the 7 bolt yes that is garbage, but a 6 bolt although is a very temprimental bitch, and i think thats why people like you think its a bad motor lol it is a very powerfull beast when cared for. and not riced out by come guy that throughs a huge turbo on it with no supporting mods and blows it up.

No the cooling jackets were poorly designed. The head was made to thin and not thick enough to be decked more than once safely. The rear main seals are shot after 60k miles. The grounding system also shit big problem with throttle cable catching ground and burning them up even on the 420 motor. The engine was total shit. Garbage I have owned 6 dsm's and a evo 3 myself. Love the cats births engines are absolute shit.

Oh no the 4G63 was a great engine....sorry I can't say that with a straight face.

Nice!

I am down for sayin it is the freaking worst by far and in second place the 420A
