Those Running 3.73 And a TF w/ LockUp.. What's your highway Driving Like?

Like I said My engine was built in 1996. There is a huge difference in technologies between then and now. I speaking about my situation, not anyone else's so don't shoot the messenger. If you don't like what I said you don't have to respond negatively. Just keep your negative thoughts to yourself. I thought I was giving thoughtful advice with my life experiences with the OD transmission. It's sad to see that the so called experts can't accept a journeyman's opinion without whining about your expert opinion. From now on don't expect anything from me. You so called experts can do everything. I have been involved in MOPAR's since 1967 and really that's what I love. Maybe you youngsters with your GenIII hemi's need to do a little research on the older engines to see where you came from. I'm in my 70's and don't need a new hemi to toot my whistle.

I wasn’t trying to be negative, not really sure how you read that into it. Maybe you missed that I was also agreeing with you? Your “life experiences” are exactly my hesitation with an A8 and most builds on here.

And to be clear, the 6.4 reference is pertinent as the OP has that exact motor in his car.

Pretty cool to be called a youngster. While I’m not in my 70’s and certainly don’t have the wealth of experience you do, I’m pretty far from being a “youngster”.
