Howdy,
Thinking of building a motor specifically for gas, or duel fuel, to have as a daily driver in the HG. I'm planning on basing it on a blue or black six - apart from the head & electronic dizzy, are these motors identical to a red motor...?
I've heard about the dizzy re-graph thing, but what compression should it run - is a set of flat-top pistons enough or does it have to be more drastic, to get the most out of going to all the expense? Also, the hardened valve seats- are they the same as you're supposed to have for ulp or harder still? Does anyone know if an efi set-up (VK for example) motor would work better than a gas-research set-up or similar?

Straight gas and dual fuel are two different things. What do you want? |

If u run straight gas u can go 12 to 1, but u cant on dual.
If u use a Blue/Black u will need to use all the anti-poll gear.
Maybe use the Head Crank and Con-rods from the Blue/Black in the Red.

I was thinking of building it to be suitable for both, mainly because of the delay it will take in getting a gas conversion these days. Does anyone know what compression a set of flat-top pistons will give?

If you are setting it for both, then I would recommend building a petrol motor, and having the gas as a price saver.
I believe if you want any real performance from gas, then you need to build a gas only motor. I built a 280hp 202 on straight gas, so |

I think your right - I'll prbably build it for petrol 'cause I have a better undertsanding of that. Just curious was your 202 still 'economical' on gas with all that horsepower or did it chew heaps too?

17 litres per 100k's or about 15 miles per gallon in oldspeak. |

I guess you can't change the laws of physics - Speed & horsepower = money build & money to run.

Actually just did some maths. If gas is half the price of fuel that's equal to about 8.5l per 100ks, which ain't so bad! Can I ask some specs of the motor? Was it cranky on the street or ok?
