Wow, that's a load. I think you need a 445 stroker kit.
What pistons did you use to get the 9.2:1 compression ratio? I've been considering swapping in a 428 crank in my 390. It looks like yours makes plenty of torque to haul my 6000lb camper.
How much total timing do you run? Have you ever had any pinging issues?

I reran your sim and changed only the cam (Lunanti 62002)
if you look at the TQ it stays steady instead of dropping off .
I believe a simple cam change will help you big time with little $ spent

That cam does make a good bit of difference. I can't wait to see what heads could do.

Is this actually real or does DD5 exaggerate that much?
I think $2500 for 200HP is a pretty good deal...

ALL PARTS off the shelf !
biggest thing I think your cam was holding things back , real strange how the TQ dropped off so quickly .
I ran a bunch of tests on DD5 when i first got it to see how accurate it was .
I had people that had actually ran their engines on the dyno send me the build specs and we compared the results . all in all it was very accurate , the FE engines for some reason always come out about 5-7% high on TQ but very close other wise .
