Anybody have this exact combo? Seems the washer pump cover might cause an issue?

Sounds interesting.......

had a 70 454/390 in the day I added 400hp tri to and it was nice but had stock ignition, no hei then. no interference issued anywhere.

68 435 here with tach drive HEI and no clearance problems. A bit tighter fit than an original distributor but definitely workable.

I know you can't see it with the hood closed but the clear cap has never caught on for me.

What about a small cap tach drive hei?

I already ran that configuration with no problems. I'm looking to "clean up" the engine bay by removing the coil & bracket & center wire.

Tom454

Not concerned about cap color.... just fitment.

The 70 has a 5 port washer pump... and a pretty big pump cover. Can you please post a pic of the washer pump and HEI relationship ?

Trying to eliminate the remote coil.

I have the big cap HEI in my 72 and it clears everything on the firewall fine (wiper motor/washer pump).

You can just see everything in the engine bay pretty good at the beginning of my video.



Obviously, I don't have the 3X2 intake, so I don't know about the rear carb that would be in front of it... but 1Fordman says in post 4 that it worked on his....

I have the HEI w/tach drive on my 74 with the tri power. No interference.

It clears the rear TriPower carb by a hair. I have a 87 Vette HEI distributor I'm detailing right now and I have the Tripower on the bench. It's the five port washer pump cover that's the question. I guess I'll just pull the distributor out of the 454 and drop in the 87 distributor to see. Thanks for all the replies. I'll be back shortly.

...It fits.

Edit:

3X2

If you're trying to not have a coil and coil wire, why not a Vertex magneto?

Tom454

Price and ease of access to replacement parts is a factor... but especially price. Those magneto's are too pricey for this project.
