LME 390
I bought LME's 1200hp aluminum 390 with Katech oil pump, Cam motion 235/248 .640/630, 118+4, 38% fuel, billet valley cover, 61cc combustion chambers , 10.65 compression ratio.
They're going to freshen and install my heads. I don't know what new valve train parts will be added but pushrods for sure. I was interested to hear that they do Hennessey's heads. 3 weeks delivery. All parts are in stock. I now have an HPE 850 with custom heads and GM short block for sale.

Not surprising, since they're pretty close, and LME does good work.
Can't wait to see the numbers. Congrats'.

I believe mine is dead or dying, and I will find out in a few weeks.

Ah…not as cool if true lol (but undoubtedly still a great engine).

As I said in my email, KaTech was my first choice, but the additional stroke in the 416 made me nervous, and your 390 parts were not in stock, but LME's are.

I wish I would have known mine was going to let go! It let me know ion the big end of a 9.5X run! My new motor ended up being a 388 from an iron L8T block. Going to the track this Sunday to see what kinda times it will run.

Did you get a chance to redyno with the new engine? Wish that L8T block wasn’t iron…but I’m sure it’s strong AF though.

I did... made 940RWHP same as the last motor but its only running about 16lbs of boost compared to my last motor that was running 20lbs. It is most def a tad heavier! I like the way the car sits lower in the front though! Made some easy hits on it with a 1.80 60 ft and it ran a 9.90 @ 147MPH The MPH makes me think it will run 9.5X maybe lower. Putting a 15 inch tire on the rear this winter to see if that helps. It really needs a 2650!

[QUOTE=Joshinator99;11376976]Well you’ve set the stage to make mondo power anyway. I think a Maggie 2650 or Whipple 3.0 is the key to feeding that bad boy (or twins lol). [/QUOTE
Yep... Don't like spending money on something twice! Who knows what this thing will end up as! lol I could have bought a copo by now! :/

My current motor makes 20-21# boost with a 2650 because cam and heads are not designed to flow that much cfm. I expect boost on this 390 to go down.
