B2 Motorsports - Mat Twiehaus 427SBF Build

[blykins]

I'm going to try something new with my Club Cobra participation. I thought it would be cool for my Club Cobra customers to get some personal thread exposure about the engine that they're getting. Not only does the customer get their build up in lights, but it gives everyone else a recipe for a desired engine output.

We'll use Mat as a guinea pig. (I did get his permission...)

So my plan is to outline the build, post pictures as the build progresses, and then post the dyno results at the end.

Mat came to me wanting a new engine for his JBL Daytona Coupe. This is primarily going to play the street car role, but Mat wanted it to be reliable and potent enough to test the abilities of the chassis.

Ok, enough for my banter...here's the rough specs:

*Dart SHP 351W Block, 4.125" Bore
*Scat 4340 4.000" Crankshaft
*Scat 6.250" H-Beam Rods
*Probe SRS Forged Pistons, 25cc Dish, 1/16, 1/16, 3mm Ring Pack
*Ported Trick Flow 225cc High Port Cylinder Heads
*Ported Edelbrock Victor Jr Intake
*Comp Cams Solid Cam, 244/252 @ .050", 110/105, .600/.610"
*Comp Cams Ultra Gold Rockers
*Quick Fuel Q-850 Carb
*MSD Pro-Billet Distributor

I really try to get away from cookie-cutter builds and although 427W's are getting fairly common these days, this one will definitely hold its own.

Instead of the traditional Canton/Moroso oil pan with Melling oil pump, we're going with a Dailey Engineering billet dry sump pan and pump system. The pump feed hole in the block gets drilled and tapped for a plug, and the oil is fed into the block externally through a multi-stage pan-mounted dry sump pump. Adding to the dry sump experience is a Peterson Fluid Systems pump mandrel, along with one of their valve cover mounted pop-off valves, and one of their valve cover mounted vacuum regulators. This particular pump is a wet/vac pump and will actually pull vacuum through the crankcase.

I plan to take some pictures of the heads and block this evening and I will post them here. I actually have everything for the build, but we're waiting on Peterson to supply the mandrel so we can get some critical dimensions to Dailey so they can build the pump.

I will also post the flow numbers for the heads and intake.

Stay tuned.....
