LOL !!!
I had one of those fuel/air bombs on wheels back when I was 16. The guy I bought it from had done some engine work like Balancing and High Compression Piston and added a 4BBL Holley carb to it.
Had the 2.0 Liter or 121 Cubic Inch engine. He sold it because it kept fouling out spark plugs because he didn’t rejet the carb to the correct Fuel/Air Ratio.
I fixed that and put NGK Spark Plugs in it. Ran like a scalded ape after that.
A buddy of mine put a 302 into a pinto. He ran it with the factory rear, as he put it, “for a very short while”before he put in a more likely rear.
