That's about the max I would want to go with on cubes. I want to be able to rev this thing. The thing is your talking about a $3000 block and $2000-2500 in a rotating assembly, just can't see how this thing totals up to over $7100.
Yeah I don't know either besides the fact that it has a custom 3.700'' sleeve and custom Diamond big bore pistons. I just don't see how that'd add 1500-2000 to the price of a forged shortblock.
There is one dyno result of the Livernois 323 big bore block, of a 2009 Bullitt Mustang with these mods:
Livernois Motorsports 323ci Big Bore Stroker Longblock
Livernois Motorsports Stage 3 CNC Heads
Livernois Motorsports Custom Camshafts(specs unknown)
Livernois Motorsports Cam Phaser Limiters
Livernois Motorsports Crankshaft Scraper
Livernois "Reload" CNC Valve Covers
C&L Intake Manifold
Innovators West Damper
Kooks Longtube Headers and X-Pipe w/ Cats
Whipple Single Blade Throttle Body
Ram Clutch
Dynotech 1-Piece Driveshaft
Ford Racing Handling Package
It made 403rwhp before the C&L intake manifold was installed, 415rwhp after. That is pretty disappointing seeing how Rich has made close to 430rwhp before with the stock bore/stroke/compression, milder heads/cams, and a dual blade TB. Yes he did make that power with a JPC manifold on his car, but that doesn't change much because that stroker is still WAY more aggressive based on several factors.
It also is disappointing knowing that Eaglestroker on s197forum/TMS made about 415rwhp with 21 less cubes, less aggressive heads/cams, dual blade TB, less HP making longtubes, and lower than stock compression.
There are definitely factors that can considerably vary dyno numbers, but one would think that a very aggressive, high comp, big cube N/A setup would make considerably more than others.
But hey, what do I know about what cars should dyno at, I'm 14. : P
