340 Stroker Build Need LOTS of Advice

I went the Eddie headed 340 11.0 comp 550 lift 240 + duration @050 single plane intake 750 Barry Grant, 3500 stall 727 trans 4.30 & 3.90 rear gear in my Duster when I first built it, it was fun for around town but it wouldn't rip the tires loose at will 265/60/15 BFG drag T/As oh and not a great converter. The 7200rpm rev limit was fun and the sound glorious but out on the open road 70 mph SUCKED. I ended up starving a main for oil in an extended power run and spun a main bearing. Being dissatisfied with the 340s torque and rear gear highway manners I chose to build the 340 block to a 422 as the bore was already .060 over. I honed the block and ordered the parts for the stroker. Changed the gears to 3.23 bought a tremec TKO 550 and would never go back to a stock stroke motor. The torque increase is so addictive stab the throttle melt the tires roll the throttle in high gear and accelerate with diesel like pull.
Two best things I've EVER done to a car big cubes in a little package and the 5 speed manual .083OD. Is it the quickest, no it ran 12.4 @118 mph 2.0 sixty foot at 4500 actual elevation the density that day was crap and racers said corrected altitude was near 8000. I have been clocked @172 mph and I have gotten over 22 MPG. Oh and a ticket at a 102 on coast down from much faster.
I'm excited for you to get a stroker good luck and happy building.
