This one will challenge your brain some. To be honest, I'm not even sure what it will do because it's got some cylinder heads that I didn't have a part in.
This is a class pulling truck engine.
*Factory 428 block, half-filled, 4.160" bore size
*Calico Coated Federal Mogul 125M main bearings, with coated Clevite H-series rod bearings
*Scat 4340 4.125" crankshaft (makes for a ~450 ci combo)
*Molnar 6.800" rods
*Racetec domed pistons, with a 1.5/1.5/3mm ring pack, compression ratio sitting right at 13:1
*Pistons sit about .008" out, using Cometic 4.250" x .051" gaskets.
*Camshaft is one of my custom billet core solid rollers. It's 257/267 @ .050", .640"/.650" lift, 112 LSA on a 112 ICL
*Morel solid roller lifters
*Les Schmader ported D2TE-AA cylinder heads. I got them and they had 3/8" valves, I stuck some new bronze valve guides in them and a set of SI stainless 2.09/1.65 11/32" valves with one of our valve jobs. I have no clue what these puppies flow. My guess is about 280-290 cfm.
*Cylinder heads are set up with PAC dual springs, PAC titanium retainers. 270 lbs seat pressure with 600 lbs open.
*Harland Sharp adjustable rockers with Harland Sharp HD shafts, POP billet spacers, stands, and end stands.
*Custom Trend 3/8" x .135" pushrods
*Intake is a very well ported (done by my boy, Lawes Mayfield) Portosonic. It will have a 2" HVH Super Sucker on it, with a Quick Fuel Q-950 carburetor
*MSD distributor, locked out
*Oiling is taken care of with a Melling HV pump, ARP shaft, inside of a Milodon 9 quart 4x4 truck pan
*No accessories will be turning on the dyno, will be driving the mechanical water pump with an external electric motor
The plan is to have it on the dyno this Friday.
As always, the game is for ****uncorrected**** horsepower. The closest without going over wins some Lykins goodies. I'll throw this in the pot too: the closest without going over combined with the peak hp rpm (guess in 250 rpm increments) will have an opportunity to buy a set of my non-adjustable rockers for $100 off retail price. They sell for $450, I'll let a set go for $350 if you so desire. If none of that makes a bit of sense, let me know, and I'll try to clarify.
Happy guessing.
