Hi Im new here and i have a few qestions.
I bought a 350 engine and put 444 exhaust 442 intake cam, eldo EPS high rise intake, headers, 750 eldo cfm carb, eccel disc cap/rotor, msd spark plugs wires, k&n air cleaner, Its on a running engine stand and WOW it really sounds great! what does these engine numbers mean? cast # is 3970010 and the head # is F0619CK1 . and under the valve cover it saids made in mexico. what does that mean? i know most gm create motor are made in mex. or are alot of 350's made in mexico?
And how much HP ad TQ do you all think it will have? It hads no air pump no A/C double timing chain.

Thanks!

Cast in Mexico, Not machined there. Pretty Common though.
