440 power gains/ aluminum head advantages?

Like I said, the dist locked out isn’t problem to me.
If it runs good like that, just leave it.
That’s not you’re missing 1.5 seconds of ET.

If your flash stall is only 2800, that’s way shy of what would be optimum with a 505/292 mega cam(you’re sure it’s the 505?).
That’s a pretty good sized cam and I’d consider a typical 10”(35-3800)converter to be the minimum I’d want for that.

I assume the heads have the correct springs, and they’re set up at the correct heights for the cam?

As another reference point……
The Isky 505/292 cam is very similar to a Racer Brown SSH-44.
I ran an SSH-44 in one of my 440 combos into the low-11’s………with a 9” converter that flashed 48-4900.

yes sure that's the cam. bought that one after cam break in failed with a comp cams and i had rebuild the whole engine again ha. and yes i can check next time i drive it but it's definitely around 3,000 flash when i launch it. it's a tci 3500 stall converter. wouldn't have been my first choice but i got it for 150 bucks and it's been good to me besides a little lower flash than i expected. i know my new timing chain had quite a bit of slop when i installed it all but didnt think much of it. im wondering if its retarding the cam too much with how much slop it has.
