4340 Forged New Molnar Technologies 4.300 Stroker Crankshaft and New Molnar 6.800 Rods with the Ford Big End Offset. Picture of Crank is Generic, I didn't want to take the Crank out of the Original Shipping Box.
The New Pistons I have on Hand are Probe Forged .080 over for a 4.440 bore which makes a 532 and 9.15 to 1 Compression with a Edelbrock RPM Head with 95 CC Combustion Chamber, a .040 thousandths Thick Head Gasket, and about .025 thousandths Deck Height. If you surface the block to .015 Deck Height the Compression will be about, 9.3 to 1.
If you choose a Head with 72 CC Combustion Chambers and use the above Gaskets with a .025 Deck Height the compression is approx 10.85 to 1. There are many ways to change compression. I have 11.5 to 1 in my street 460 and run 90 Octane Non Ethanol Pump Gas. With 10.5 you could probably use 87.
Another set of pistons I have are Forged Flat Top ICon Pistons .040 over to make 523 Cubic Inches with the 4.300 Stroke and 6.800 Rods. These Pistons are made for Kaase P51 Heads and Ford Racing SCJ Heads. With a 72 CC Combustion Chamber and using the parts and Specs listed above compression will approx 13 to 1. With a 76 CC Chamber you get about 12.14 to 1. With a 95 CC Head the compression is about, 10.3 to 1.
The Crank and Rods and Choice of Pistons are priced at, $2,850.00. Please call with any questions and take a minute to look at my other ads.
