That looks like an LME motor to me.... Make sure that if you use head studs you can pull the heads without pulling the motor. Might want to reconsider to using ARP head bolts. Just my 2.

Nice setup, but I have to agree with Vince. Why iron? Get an LS2 block and do a 402.
It's a lot lighter and cooling will be better. It's really not that much more money.
You can pull the heads without any problems
We do them all the time.
The studs have a hex broached in the end. You just loosen the nuts and take the studs out just like a bolt.
Actually, the head will slip over the studs without removing them anyway.

Hmmmm, I dont think late Model engines would use Scat parts. Sounds like more of a Texas Speed, or SDPC motor to me.
LME only uses quality parts..I think you'd have to beg them to run those internals.

I'm shopping around for the cam, so if you have any opinions/recomendations, I would like to hear them! !
Also, anyone here running a 408 with a blower? ?

Hi Mike,
I am running a HKE 408 with my little A&A P1SC blower (D1SC or F1A in the future)
I followed Erik's advice and went with a 238/242 on 115+3 LSA. I love the way the car sounds. I am running a 2800 TC and the car idles great at 900 RPM. I just love the way my car runs and sounds (well, when it used to run as I blew my tranny and the car is on the lift
)
I also asked Dr Phil what he thinks about the cam and he told me it's a good choice.
Here are the motor specs:
HKE 408 at 9.1 compression
ETP LS1 230cc runners heads
238/242 on 115+3 LSA camshaft
Eagle crank, Callies Rods, Wiseco pistons
A&A P1SC with a 3.55 pulley (over 10# of boost)
With the D1SC, the numbers will be sick!!! Keep us posted
