#4 Torque Hone the Block
For me to do this project right I decided to have the Block Torque Honed and turn the engine building over to Brent at B2 Motorsports. The block cleaned up at .003 on number 5 hole and all holes were honed to .003 over. Since this is now going to be a rebuild the block has been squared and decked .005, also has been line honed (mains) I ordered ARP Main bolts to replace the stock Ford main bolts. These have to be used when you line hone the mains, whatever fastener is going on the mains has to be the ones torqued when the line honing is preformed. New ARP head bolts will be used in favor of the original Ford bolts. The pistons will be Diamond Forged Custom Pistons .003 over, changing the cam to one Brent specified, a bullet Custom grind Solid lifter flat tappet cam. Will be using Competition Cam lifters, and custom Trend Pushrods, new Rollermatic Billet timing sprockets for the cam and crank. In checking the cc's of my Edelbrock Heads they were found to be 79 cc instead of the advertised 76cc heads. We are shooting for 10.25 - 10.50 to 1 compression ratio. Will be using the existing Blue Thunder dual plane single 4 intake and the MSD Pro Billet Distributor. So now it's clean all parts up, strip and repaint the bell housing and backing plate. Powder coat some parts and get ready to re-assemble the motor. Brent will break in the cam on the Dyno at his shop and then adjust and tune before he does a Dyno pull to see what we've got. Now it's waiting for the custom Pistons and Cam, once the pistons arrive the Rotating Assembly will have to be re-balanced, with the lighter pistons the crank counterweights will most likely have to be lightened. Shively Speed Machine in Louisville, KY is doing the machine work and balancing. Will check back in 2-3 weeks.
