Hey All,
Just a breif history, I am slowly building a stroker engine for a boat that I am building. I had settled on the thought of making it a 470.
I finally got word that my 78 400 block is sound, and can be bored out without any worries. Now that I know that, I am putting together my shopping list. Right now I am just focusing on the pistons, rods, and crank.
So, what I have so far is a crank from Molnar:
3910NC6F 383/400 Chrysler - Rod Pins = 2.200", stroke =3.910, minimum rod length= 6.450 bob weight = 2300.
Molnar rods from Chevy BB:
CH6535VTB8-A Center to center = 6.535, grams = 736, bolt = 7/16", BE bore 2.325, Pin size = 0.990, BE width = 0.992, PE width = 1.065.
Then the piston might not be right. I had selected a Wiseco Piston, PT108H55.
Bore 4.375"
Comp Height 1.25
Comp Ratio @ 78cc 10.3:1
Comp Ratio @ 88CC 9.4:1
Dome Volume -10cc
Gram Weight 451
Rod 6.800"
Stroke 3.750"
Am I on the right track for these parts, or do I need to look at something different?
Thank you for any help!
