Well for a year Ive wanted to do this, but never had enough income and now I do. So Ive decided 4.6L is the way to go. Ive spend countless hours studying Dino's page, and other links. Now Ive finally come up with something, and I just need some suggestions and someone to double check what Ive come up with.
Now for the math, and towards the bottom Ill put all the nifty gadgets and plans.
Bore: 3.905
Stroker: 3.895
Deck Height: 9.418
Head Gasket: 0.045
Combustion Chamber Volume: 56.4
Piston Dish Volume: 22.0
Rod Length: 5.875
Piston Pin Height: 1.585
-----------------------
Compression Ratio: 9.56:1
Quench: 0.0555 +0.018over
Deck Clearance: 0.0105
Rotating Length: 9.408
Rod/Stroke Length: 1.508
Rod Angle @ 90*: 18.647
Rod Centerline to Piston Top: 7.460
Cylinder Displacement: 279.9ci
CALCULATIONS PROVIDED BY: AndreasStrokerCalc
Now the CR is very close to what I want being 9.5:1 so I should still be able to run premium fuel without any additives, since this is a daily driver. I will be using Ford 24# injectors with adjustable MAP and FPR. Quench height is TDC to head right? The calculator I used showed in the green so that means I wont get valve lash right? I dont unsderstand what combustion chamber volume is so if someone can clear that up for me that would be great.
As far as parts go:
1988 4.0L Long Block
1991 4.0L HO Head
2001 Intake Manifold
Ford 65MM Throttle Body
4.2L Rods
4.2L Crank(12 Counterweight)
3.905 Federal Mongul Cast Pistons
260/272 Crane Camshaft
DIY Gasket Match Port/Polish
Bore & Hone (Kind of a Duhh)
Valves Laped(Is that the correct term?)
Mopar Performance Valve Springs
Harland Sharp Rocker Arm 1.6
I think thats most of it, probally missed something, just jump in and tell me. Thanks much.
