What work was done on Wilfred's engine?

Many people have asked me what we were having done to Wilfred's engine for the gas conversion.

Well that is like opening a can of worms as each and every engine will be different and the costs reflect this.

Geoff found some things did not need much work in some areas but others might have to fork out a lot more to fix before the gas conversion commences.

Here is a list of things that Geoff had to do to prepare the old dog for some gas....
  • crank grind to suit the case 0.002" clearance (standard)
  • new Billett camshaft C-25 234* AT 0.050" lift
  • ceramic coated piston skirts
  • new rings
  • new cylinder heads AMC (made in Brazil)
  • modified inlet port 8.75:1.0 compression ratio
  • manifold - tuned length progressive Plenum style
  • Inpico 300a (mixer) gas carby on 32/36mm throtle bases
Just before I left Geoff showed me pics he took of Wilfred's engine being taken apart ready to add all nis new bits and tits ....:o ..... can't wait for him to burn me a disc and mail it down to me to post on the forums.

Some more pics to go with Geoff's diagram

First of all there is the filler inlet. Instead of cutting another hole like some dodgy gas fitters do we used the same inlet as the petrol tank. Yes we removed the petrol tank ........ before you ask.

Geoff's Diagram ..... section on the filler and gas tank



Filler inlet in the same place as the old petrol tank



Gas tank 72/75 litres



Here is the safety mechanisms on the gas tank behind the magic box



Some people may ask why the tank is sitting a bit forward of the missing fire wall. Well when Geoff was fitting the tank he found a patch of rust which we are addressing as part of Wilfred's resto ..... hence the slightly forward stance at this moment in time.

Here is the section where the liquid gas in piped to the converter where it meets hot oil and converts the liquid fuel into a gaseous state.

Geoff's diagram section

Converter into Manifold and Carby

Here is the next stage where the transformed liquid has been converted into a gas and heads towards the progressive Plenum style tuned length manifold



Here is the converter feeding into the manifold

Here is the manifold with its tuned length progressive Plenum style manifold. It has a Inpico 300a gas carby on 32/36 throtle base

Here is the converter photographed upsidedown so you can read it.

In Winter Geoff says the button in the middle can be primed to help start the engine on a cold morning...... as this is a common problem with some gas conversions.
