how sure are you of the year on that motor?

02 Ls1s typically had MLS gaskets and if you look in the valley of that motor you see a BOSS that is on the early LS1s. When installing a LS6 valley cover this needs removed. In 01+ they started using LS6 blocks in Fbodys but the Ls1s of those yrs also go the treatment of not having that boss in the valley

MS3 is a beast of a cam and can be made to make great power and have good drivability.

also a blue 68 is a sick truck...one day i hope to have one
Not really sure what kind of head gaskets were on it. They were removed before I got the engine. No I'm really not for sure what the engine came from. Are there some stamping #'s I need to look for to know exactly what I have? The LS1 valley cover I got from zebra( came off his Vette, I beleive.) fits just fine.

I know the MS3 is a great cam, but I'm afraid it's going to be too much cam for my particular application. If I could get by with about a 2500-2800 stall with it, I'd run it. I'm just worried that with the TH350 and 3.07 gears, it will come into power too late to use it where I need it.

Here's a better pic of my truck.
