saving to go to a new block for my TA I just read a thread has made me want to go with a LS2 or a LS7 block instead of forging my 100k mile LS1 & adding on FI. I'm definately new to engine building and very curious about what mods could be universal from the LS1 to the LS2 or LS7... the same headers, fuel rail covers, clutch, etc.
What I want my car to do:
I want my TA to be streetable that puts out at near 500rwhp that can run mid 10s to low 11s at the track & still get at least 22mpg on (91) the highway. Once my car can reach 10s I'll be satisfied and won't be looking hardly anymore to add power. Would I be able to reach 500rwhp if I'm at 420 now if I have my engine rebuilt with forged pistons, rods, crankshaft, and add on an affordable FI? What would rebuilding the engine cost me?
Budget will be shallow. Probably nothing much more than 4000 on a shortblock. If I can get by under $5000 for a complete engine swap (including the money I get off my LS1), there's a chance I can do this within a year or two.
And what could I get out of my 100k LS1 with a custom comp grind cam & ported & polished LS6 heads?

SDPC LS2 402 would be within your budget. There are also others that build fantastic motors or have the sources to do so. Richard at West Coast Cylinder Heads would be another very valuble resource. Lots of folks talk VERY highly of Steve at Race Engine Development.
As I've said before the research can be half the fun and will definitely give you peace of mind when forking $4k+ for a shortblock.
Why not reuse your LS6 heads?
Good luck

No problem on the LS6 intake. An LS2 intake with a 90mm TB upgrade will a bit better with a cube upgrade but lots of 382/402 folks do just fine with the LS6 intake. Guess it depends on your budget. A factory LS2 comes with the LS6 243 castings... heads will not be a problem. The cam? I would recommend discussing that with your engine builder... there is a chance it could be reused... but I think you might come up with a cam better matched for the increased cubes...
