double or twin distributor drive

This an LT1 correct? It came with electronic fuel injection and ignition via a crank sensor. Now you want to remove the technology that makes that a great motor and install a mechanical distributor and a mechanical fuel pump? Talk about going backwards and expensive. For what!!

In one posting your complaining about not having $ for internet, but then your talking about spending lots of what you don't have to re-engineer a system that works perfectly.

I don't understand!!!!!!!

 

Why doesn't he just get one of the distributors that have the fuel pump systems built into them. I think they were made by Hilborn, weren't they?

 

yes, it is an LT1, and I am working on a simular LSX.

The thing that makes it imperfect to me is that it was designed so that I could not fix it beside the road, as well as having preset fuel perimiters. I never said that I wanted to use a mechanical fuel pump. It has a 90 PSI fuel injection pump on it off of a ford van with a fi 351 that does not go inside the tank. The second distributor will drive an electromechanical fuel injection system that does not use a computer, a system that self diagnoses using LED's. I have bench tested the system, I know it works, Im just trying to get it on the engine.

 

Hilborn is a drool system if it is the same system as the bendex/ roschester, when one injector fires, all the injectors fire. the TPI systems were a bank fire system, the later LT1's were sequential, my system is sequential.

Figure out how to run two of these off the front of the cam.
Shouldn't be too hard.

 

So you are doing something similar to the Lucas timed injection with a metering unit that needs to be driven at 1/2 engine speed?

There are some pics here of different drive setups, but nothing like a v-drive setup.

So, pardon my ignorance, but are those WICOs anything special, or run of the mill Farmall type mags??

 

Dave,
Are you looking for a 90deg pulse generator? If so, you may not need a second distributor, just a second pickup inside the ignition distributor.

 

I will need the second distributor to be able to adjust the fuel injection seperate from setting the ignition timing. I do not want to give up either the vaccum advance, the mechanical advance, or the automatic dwell adjustment built into the HEI. I will also be using the mechanical advance as well as the vaccum advance in the fuel injection distributor. I have located the parts I need to make the dual drive, as well as a potentual modifyable assembly, so things are moving forward now.

 

Cool. Keep us posted and post some pics if you would. I'm interested to see it come together.

 

same ones in old lawnmowers and tractors. its hard to find them with 2 or 4 spark plugs though.
