I'm building this 2270 and I thought this would be a good one to document. I'm going to try and cover every little aspect of the build, although I'm not necessarily going to break down every process into a step by step.
I'm starting with a 1.7 'W' case. I did a quick line bore check and it's a nice STD case. But more on that later when I actually measure the line bore accurately. Case Preparation - In this section I'm covering all the modifications and inspections to be done on the bare case. Threaded Gallery Plugs, Resurface Oil Filter Mount I used my slide hammer setup to pull the original gallery plugs. I'm just doing the 'normal five'. In this picture also shows the oil filter mount face - I pull the studs and true the surface up to ensure a good, leak-free seal. ![]() HV Oil Pump I have a Schadek oil pump that I've cut in half to mark the case for 'port matching' the oil pump. The ports on the case are smaller than the oil pump, so this simply eases the transition. I use a carbide cutter for aluminum in a pneumatic die grinder to carefully open up the holes. ![]() ![]() Cleaning Stud Threads I chased all the M8x1.25 studs on the case. This eases installation, but also ensures more accurate torque. Any fastener that has a specific torque value should have clean threads. The rust/dirt/sealant/etc on the surface will make the fastener harder to turn, which means you're getting a slightly false torque reading. You'll see the head studs have all been removed. I don't use a tap or die to clean the head stud or the case threads because I've seen this result in loose head studs. I don't touch this parts of the case, and I use a wire wheel on the bench top grinder to clean the threads without risk of removing material. ![]() |

Just Curious if there is some additional welding that might help add some support to that part or area.... Not that I know of. I've only seen one case where this happened. I don't use a torque wrench, but I do use sealant on the gaskets since that sump plate doesn't get opened up very often.what does a 2270 long block (minus core charge) run these days? In the $7k neighborhood.what's the ruling on a 2270, can it run well on D jet or L jet - OR - must it be dual carbs or aftermarket electronic fuel injection? There is a thread running right now about L-Jet on a 2270. I think any stock FI would be a kludge. Carbs or aftermarket FI will always be my recommendation. And I'm not a huge fan of carbs, unless you spend a lot of time (i.e. $) on them to make them really nice.Is this motor for one of your cars, or a customer? And any reason to start with a 1.7 case? This is for me. I have four cars ya know. (IMG:style_emoticons/default/laugh.gif)The cases are all pretty much the same, so whatever measures good. I tend to feel that the 1.7 engines had an easier life, but this case was literally just pulled from the pile and happened to be a W case. |
