I discovered this thread and read all teh way thru. Congrats on your success in such ambitious modifications.Nah shouldn't be. There's a lot of stiffening that was done to begin with because I was planning on a 512 stroker at some point. The engine will be significantly heavier, but we're not talking orders of magnitude heavier, just a couple hundred pounds. With how tall the T444E (7.3) is, It'll be above the hood line, so I'm talking with a buddy of mine that owns PFC here in Kansas about modifying the hood into a wide cowl, induction hood.
Although I do think @LocuMob brought up a good point on weight.
I knew a T444E and E4OD are a lot more than a couple hundred pounds heavier than a 4.6 SOHC and 4R70W. Googled it and T444E alone is 920 dry vs 485 for an iron-block 4.6. (I didn't bother on the trans, but I'm confident it's heavier also)
Plus you've got that large boxtube + pillowblocks + swaybar arms: that is surely +50lbs over a factory swaybar?
That's a lot more weight on those Vic suspension pieces and joints. Does that extra weight equate to the abuse and rigors of what the P71s were designed for in police use? Perhaps, but there's no way to know, this is uncharted territory.
Also, the wheelbase of the Dodge is 121", and the Vic is ~115", so your Ackerman is off a bit and you might get tire scrub in tight parking-lot turns. When most folks attempt a R&P steering mod, they seem to use the C-body LBJs and swap them side-side to use a front-mount rack, which destroys Ackerman. But you've used the Vic steering arms, which is a huge benefit to correct geometry. But the longer WB of the Dodge means your Ackerman point is now further forward (assuming the front track is at Vic spec). Chrysler saw fit to use the same Ackerman with 119" or 121" WB, so there's obviously some flexibility, but this is ~5" further away. Will it matter? I don't know.
Anyway, that's just some stuff to think about during your shakedown driving. Likely all will be OK, and you'll still be within the safety factor of all teh OEM pieces.
