FS: Forged 370CI longblock Up for sale is my recently built 370CI. motor. The motor has maybe around 2,000-2,500 miles on it. I'm just trying to see if I can sell it to go even bigger 
. So here's the breakdown of it.
-6.0L block bored .030 over. (Block has around 50,xxx miles itself)
-ARP Main stud kit
-Stock Crank
-H Beam Rods 6.125
-Clevite 77 Racing bearings used throughout
-Mahle Pistons (Flat top -2cc Valve Reliefs) Also, rings are file fitted for a 200 shot.
-Ported and milled 243's (LS6 for the ones that don't know.) These heads were milled .025 so the compression is around 11:1
-PRC Dual Valve Springs
-Brand new Manley Stainless (stock size) valves.
-GM MLS .051 Head Gaskets
-Custom Comp Cam spec'd by Patrick G (238/246 .605/.613 110+2 LSA)
-Victor Jr Intake (No fittings included)
-Melling Oil Pump
-ARP Head Bolts
-ARP Rod Bolts
-LS7 lifters
-LS1 Valley (LS6 does not go with it.)
If there's anything else you'd like to know about the motor just post up or PM me. Looking to get $4,600 OBO. Can't stress the obo enough.
The motor has been to the track about 3 weekends. First weekend out I got Runner-Up in No/Electronics and the third weekend out I won the Razorback Nationals, also in No/Electronics.
Has a best 1/8th mile ET of 6.68 @ 102.10. 60' was a 1.431 in a 3,560lb F-Body.
That should be plenty of pictures

let me think about this one- I've been looking to do a rebuild on my LS2, but this would save me the trouble but it would not be stroked-
I would then have 243 heads and the block can remain intact-
hopefully you're not in a hurry to sell.....this is a tough choice.

Differences between the LS2 or 6 Valley pan and the LS1 valley pan- It doesn't look like the same pattern to use my LS2 and I wouldn't want to overlook a minor detail.
RPM range for the cam?
There are a few engines in the F/S section to sort through =

The cam can see 7000RPMS easily. I'd say around 3500-7200 is about the range for it.
