I drive my car a lot. I run TSD, Monte Carlo and touring rallies and have run events to Las Vegas, Santa Cruz, Austin, Texas and all over California. I have probably put 200,000 miles on my Arntz Cobra over the last 32 years and just spent 4 months rebuilding the engine. Again! This is the third rebuild on the the third engine. It's a '74 400 block. I don't want to do this again. Carburetors leak too much fuel in the engine during cold starts and that washes the
oil off the cylinder bores and causes them to wear rapidly. EFI on modern cars has reduced engine wear so that they last much longer.
So I got a "Black Friday" deal on a Holley Sniper EFI system and have been gathering parts to complete the project. I bought a tanks.inc fuel pump system to fit the pump in the gas tank. I got an extra Walbro pump as a backup, a bunch of 3/8" brake line and the biggest EFI fuel filter I could find.
I have read everything I could find about the conversion on the internet and I have installed a mild Comp cam that makes plenty of vacuum and mid range power. The new Total Seal rings have seated nicely in the freshly honed cylinders and I have found and fixed all the
oil leaks. I am about ready to start pulling the old parts off the car.
I plan to pull the old tank out first and have it cleaned and pressure tested. Then, start installing all the new stuff. I would guess that some of you have already done this and you may have gone through some learning experiences that you may like to share?
