| I am building a puller motor and need to know a few tips, first, will WD-45 deisel rods fit into a g226 motor and is it worth the trouble? If so, does anyone have a recommendation on which piston to pair with it? I am planning on putting 190 valves in it with the tall head, using a D17 intake that has been opened up, an EGleaner camshaft and a 170 carburetor. Will this setup do anything or am I way off base and need to go in a different direction? I am a true rookie at this and would love some input. |

| After finding someone to regrind/offset grind your crankshaft, you will have a 4 7/8" stroke instead of 4 1/2" stroke using the diesel rods. It does nothing for compression with a stock 4 inch bore piston, so you'll have to find a piston tall enough to make some compression. Also the diesel rods need a piston with wrist pin keepers or pin buttons to keep the piston pin where it belongs. Never used 190 valves and I doubt they would even be worth the trouble. "E" Gleaner camshaft is nothing different that a WC-WD-WD45-D17-170 for grind. Be careful installing different camshaft without knowing your oil pump drive teeth count. One-Seventy carb isn't anything special either. |

| Ok, that helps me out, I will stay away from the diesel rods and keep the stock rods and WD45 crank that I have now, what pistons would you recommend to get more compression? Are the distillate/over 8000 feet of altitude pistons a way to go? What carburetor do you recommend instead of the 170? Thanks in advance for the help! |

| Also, I haven't purchased an oil pump yet, will an EGleaner pump fit into the WD45 pan? |

| go with m&w 4.125 pistons i would use stock oil pump have a cam ground and degree it in at 104 or 105 that should gain you some power oh get a MS 464 from a wd45 |

| You said it was a G-226..........you have a WD-45 crank and block?? that's W-226. "E" Gleaner oil pump fits and use the E camshaft to drive it. Kinda late to be building an engine for a Puller.....especially if you need anything special for parts. |

I have a set of 4 1/8" M&W pistons that I am using in my WF block. I also have a WD45 (4 1/2" stroke) crankshaft coming. Will I have any clearance problems on the head? I am having the head milled just enough to flatten it out. Any recommendation on who to get to regrind a cam? I was hoping to get it going for this season (which is still a month away up here), but it's looking more like 2015 for me. |

| If they are truly M&W model SP-46 pistons with the heart-shaped bowl, you'll need to mill off .170" or so to keep from hitting the cylinder head. |

| Unless you are dead set on building an engine, and can do a lot of it yourself, buying one already done is probably the cheapest route. Find someone who is getting out of pulling and buy the tractor. |
