Has anyone used the Gen7 block from Dart to build a forged 496HO or 540HO?
In an effort to turn up the juice on my 496HO, I was thinking of the following.
Phase I: Dana exhaust
Phase II: Raylar 525 kit
Phase III: Slide a forged dart shortblock (540+ cuins) under the Raylar heads.
I could see Phase III requiring some ECU work and/or some injectors
Spread the cost over 3-4 years. Hopefully have some reliable motivation between phases.
I have heard nothing about the Dart block (or rumored shortblock) being used.
The information on Dart's site Gen 7 Chevy Big Block
doesn't really indicate max bore size, so I'm not sure this is a real option or just a stock replacement block for industrial engine builders. It would be interesting to know if that block would take a 4.5 or 4.6 bore or not. A 540-565 forged shortblock with a Raylar top end Might make for a well mannered combination.
Options and prices seem to be undercover for 496 owners. I'm surprised there isn't more love for this overgrown LS motor. I've been watching for Gen7 builds but haven't seen much.
