Taking a couple engines to be dyno'd this Friday. One of which is kind of a "resto-mod" 428CJ deal for a local Thunderbird build. Rules are the same for this one: closest without going over, on *corrected* numbers, will get some free goodies.
*Factory 428 block, 4.140"
*Factory 428 crank, .010"/.010"
*Scat 6.490" rods
*Racetec forged pistons, 1.5/1.5/3mm standard tension ring pack
*Federal Mogul main/rod bearings, rod bearings Calico coated
*One of my custom camshafts, 227/235 @ .050", .600/.612" lift, 112/106 LSA
*Morel hydraulic roller lifters
*9.5:1 compression ratio
*Factory C8OE-N heads, 2.09/1.65 11/32" SI valves, Comp Cams valvetrain, no port work, just good valve job
*Performer RPM intake manifold with plenum divider modifications
*Quick Fuel HR-750 carburetor with choke horn
*Lykins Motorsports non-adjustable roller rockers with POP billet stands, end stands, and spacers
*MSD distributor
*Canton rear sump pickup and pan, Melling standard volume pump
*Edelbrock water pump
Engine has no accessories that will be turning on the dyno.
So, closest on that one without going over with win some free Lykins Motorsports decals.
BONUS:
I'm also taking a 289 that's destined for an ERA Slabside 289 Cobra replica.
Whomever guesses the closest on BOTH engines (this means you have to make a guess for both to be eligible), will win a new set of my rocker arm stand shims that should be arriving next week.
Here's the specs for the 289:
*Factory 289 block, 4.030" bore size
*Factory 289 crankshaft, .010"/.010"
*Scat 5.325" I-beam SBF connecting rods
*Racetec forged pistons, 1.5/1.5/3mm standard tension ring pack
*Compression ratio is 9.7:1
*One of my custom hydraulic rollers, 219/227 @ .050", 110 LSA, .560"/.560"
*Morel hydraulic roller lifters
*Milodon stock style pan and pickup with extra capacity
*World Products Windsor Jr. cylinder heads, no port work, 1.940"/1.600" valves, Comp Cams valvetrain
*Comp Cams full roller rocker arms
*Blue Thunder "Cobra" dual plane intake
