Lake Speed's Ford C3 NASCAR Engine: Drag Racing Legend Greg Anderson Machines The Block!

What happens here

The operator sets up the Rottler H80 machine, inputting the bore spacing (4.380 inches for a Ford engine block) and other initial parameters. The machine's advanced features include crash detection and the ability to automatically sense tight spots in the cylinder bore, spending more time in those areas to achieve perfect roundness and straightness. The honing process begins with a low load (20% load) to prevent cylinder wall 'breathing' (distortion from excessive pressure). The machine runs a dry stroke first to ensure no mechanical interference, then proceeds with the honing cycle. The objective is to remove minimal material while correcting any imperfections, aiming for a perfectly straight and round bore.

Goal: Execute the precision honing process on the engine block.

Tools and materials

  • Engine Block — The component being honed
  • Rottler H80 CNC Honing Machine Rottler — Automated precision honing of cylinder bores

know what on a block like this we know what the four spacing is between so we punch those numbers in and for 380 i believe it's before four spacing so for 380 which moves over for 380 it moves over four 380 moves over so that's very simple to do same thing with the other bank we have to go through it and set the locations on the other bank the same way so but anyway we're on bank one or the odd bank as we call it so we're going to start on cylinder one so we'll we'll take our cone head and we'll go down into the blower we'll get our stones fairly close to the cellar wall and then we'll let the stones themselves or the diamonds themselves find where zero is contact so we'll find themed stones the diameter it'll automatically bring the stones out to the cylinder wall and stop the size of the film so the top there so now we zero the stones at that diameter right there and that's our starting point so then we tell it well how much do we want to take out of it to start with so we set a value in here and and we don't know yet on this particular block how much it's going to take how crooked it is how much it's going to take to get around and we're not looking to hone out several thousands we're looking to take it as much as it needs to go to be perfectly straight and that's basically the size we're going to stop at then we're going to order our pistons for that size but since we do not know it's been many many years since this block's been run we don't know how each cylinder is going to be how crooked each cylinder is going to be and how much it's going to take we have to find out what it's going to take to clean up every cylinder to be the same size and perfectly round so that's what we're going to do here so we're just going to start at a real small value here let's just start at a a half a thousand just to see what happens at a half a thousand and see if it will clean up so now the machine basically knows where where the wall is what size it is when we punch that value in it's going to go that same size on every hole it goes to so basically when it's done it'll have every hole the exact same size so if that's not enough to clean the bore completely and make it perfectly round then we'll increase that size and we'll go through them again so the correct order of operations is to get your blocks set up first and then order your pistons to match the blocks that's the correct way if you have a lot of confidence in where your block is going to come in or where it's…
