this is the message that i recieved from spec about getting the flywheel rebalanced. what do you think.That flywheel does not have the same center bore and crank pattern as the
5.0L, so it would take more than balancing. Have you heard of people
redrilling the crank flange? I would not recommend that, as I don't think
there is enough meat in that flange . I like my legs and feet.
I will double check...I know the 3.8 is the same as the 4.6L...I think the
5. and 4.6 are different. I'll verify and get right back to you...

? are you 100% sure? i was under the impression that it fit. i thought
the 3.8l v6 was a 302 without the last two cylinders?
He is talking about balance and he is correct. The 4.6 and 5.4 in many cases are different. Most 4.6's have a 6 bolt crank that is the same bolt pattern as 302 and 3.8 engines. All 5.4's have an 8 bolt crank and will not bolt on.ZeroRain said:alright i have lost all respect for SPEC
