Assuming you have a limited slip differential from the 60's/70's they were not designed for synthetic and may slip too much.

Today I finished the Holley Sniper EFI setup (MSD6L, Dual sync Holley distributor etc.)
After going through 17 steps check list i tried to start the engine for the first time with the EFI.
It worked!
Started after about half turn of the engine and runs smoothly.
:cool:

Congratulations! Have you taken any rough measurements of hood clearance between the top of your aircleaner and the underside of the hood?
I forgot to mention. It fits with no problem.

Guys, especially Mel,
many thanks for all the help :)

Today we drove the first 100 miles with my Bubble blower.
Of course it is not 100% finished yet. Some minor works have to be done yet.

Engine works as new one.
It is powerful as hell (although I did not exceed 2600 RPM so far)
Holley Sniper EFI works very fine and has very spontaneous reaction on the throttle.
Six speed Tremec is really fun to drive.
Driving ability and agility of the car is not comparable to the standard suspension (but there is an issue. I will describe it in the suspension thread)

Thanks for posting the video, looks great and sounds great. I'm sure that car will turn heads seeing how rare it is in your part of the world. Lots of luck and great to hear and see it turned out so well.

Hi, after some time,

Do you know what are the correct OHM values for 1967 fuel sending unit?
0-35 or 0-93 Ohm or different values?

Thank you

From what I see 64 used 30 ohms, 65 and up used 90 ohms.

Hi guys.
Here are 2 videos. The first is from October 2017 before I started to change the things. The second one is after all the things I’ve done.
Even the sound changed dramatically.
