Ok here is how it is shaping up:

My stock engine

125k miles (5k miles since re-ring)
LT4 hot cam
ported heads with 2.0" intake valves, milled .020
shorty headers
ORY pipe
cat back

Vortech V-1 with 6 psi pulleys
Crane ignition
36# Ford Blue top injectors
PCM tuned for boost

I know it's hard to predict grenading engines, but I need to know what needs to be changed. I am too poor right now to get a forged low CR engine built (gotta get married someday...) so I might try this and see if I can make it work. Please give me ideas about what should be changed (if it's gonna blow up in your opinion). I know I need longtubes, but I don't have the $$$ for them now. I just had to re-ring the engine 5k miles ago, the cylinders and pistons looked great so I reused them. Help needed !

 

I would say you need to lower your compression some. If it were me and I couldn'y afford rebuilding the engine, I would pull the heads, take them to a good machine shop and have them work the combustion chambers to get as many cc's as possible out of them. Then re-install the heads using a thicker head gasket. Be sure not to go too thick on the head gaskets, .060 to .070 quench is the max. If you could get your compression ratio down some to maybe 9.8 or 10. to 1 it might live a little while.
