I'm trying to find out myself....
I might look at the library for a copy of March '97's Hi-tech perf....
I like the 3.85 stroke vs a 4.00
The dyno results with the TPIS 409 cam are nice too...

Maybe just sonic test a few LT1 blocks.... There always is a variance between different blocks... You could find one without core shift that could be punched out that far. That 409 has a milder cam and minimal headwork as compared to highest RWHP cars on here... Basically ported stock heads and a street cam for that displacement.
you could sleeve too but have them installed via cryo...
IMHO a GEN III aftermarket block would do well...
A GEN I is already doing well... With a few models and MFG's to chose from...

A Gen 2 block would be a waste. I don't see anyone buying them. The LT1 design never took off really. I would buy an aftermarket Gen 3 block. The LS1 design is awesome but obviously has its shortfalls. My next project is going to be with a C5R block, but for $5000, it's going to be a while. Maybe by then they'll have something just as nice and about half that price.
