I've already been high 1.4's a couple of times with the old motor, although 1.5's were the norm..... 1.4's with the new motor will be easy. But, as most already know, the D44 starts breaking things once you get to mid 1.4's and quicker.
My best so far is a 1.71 60ft. It dead hooked. I am hoping to run a 1.6 60ft on motor and not spray the 200 shot till after it shifts to 2nd gear. I think spraying in 1st with my new combo will toast my D36. It has the 3.07 gear so that helps some but I don't think I can run a 1.5X 60ft without risking breakage. I think I'm going to do an Azzato solid rear next year or the year after. He does my tuning, I went to his house this past fall and looked at his setup. It is pretty slick. I laid under his car for about 5 minutes looking at it all. I like it.
Azzato is an old friend, we've talked a 1000 times about this stuff... and yeah, I'll eventually be getting the same rear.
For many years I raced a Dana 36, albeit that was just with a modified 350, I went to a Dana 44 after I "finally" blew-up the 36.... it lasted, and I'm not exaggerating, 1000 1/4 mile passes before it blew up, all on slicks and running mostly 1.6x at that time. As a note, the Dana 36 did great if you kept it straight, mine finally exploded about 10 feet out on the strip after I had gotten a little squirrely, I feathered the throttle to re-hook up, it did, but I was at an angle, thus pressure on the spiders..... they didn't make it, literally 100 different pieces. But, if I had kept it straight, I think it would have kept right on going.... but not sure.
With your set-up, I think your converter is too tight for the HSR..... I think 2800 is too tight for a superram, let alone an HSR. With your new stroker motor as per your signature, and a 3400 rpm converter, I'm betting you could run low 1.5's on the motor..... add the nitrous and you're well into the 1.4's...... but just guessing.
