With the 250, 3.0:1 rear gear and T5 overdrive, it just cannot keep up with today's freeway traffic. The 250 needs some work. It has a miss but runs ok. I just do not want to spend any money on a six. Plus, I have several extra new v8 engines to choose from, so why not.
I hate the sound of a six. It can never be made to sound “right” in my opinion.

Not trying to talk you out of replacing your 6 just giving you my experiences with mine. The original engine in my car was a 250 - 6 with a 3 speed and a 3.0 rear. I pulled a camper trailer up into the mountains of Arizona with it up to 8,500ft. But it used more oil than gas so I swaped out for the same reason.

So after you did the Shelby drop on the front end how high should it sit in front? It seems like it dropped 3 inches. I changed out the rear springs and it seems like it jacked it up in the rear 3 inches. It rides real smooth in the rear and doesn't bottom out.

new kia stinger is super fast...I have a friend just bought one.



 

    At our local speedway on Thursday nights during the summer they have 300 foot 1 on 1 street drags.

There was a orange and black Kia Stinger there with twin turbos.   It kicked everyone's -oh no I used a word I shouldn't have- that the street drags.  There were pro street cars there and even some Tesla's there too.  No one could beat it!   

The following week there was a Jeep Grand Cherokee with a hell cat and twin Turbos.   It barely beat the Stinger...LOL   Had to have over 1000 hp.  
 

69 PO did Shelby drop before I bought it the first time. I do not know if it has original springs or not.  Will post pics and dimensions when I get it back together. Rear axles are out of it now getting new bearings and brakes.  The fitth gear overdrive is pretty useless if there is any uphill challenge.
