I had my 1968 Chevelle since 2017 and from then till now it had its original 307 motor with around 58k original miles. The 307 was built with an aggressive cam, headers, dual exhaust, performance heads, and intake. The motor was pretty peppy but with it being carbureted it would be finicky at times. For example, when I would try to turn the vehicle on after not driving it for 5 days it would have a rough start and would take a minute to warm up. Sometimes it would run too rich and I would have to manually adjust the carb. Another reason would be whenever I would drive the Chevelle you could smell it on me. If you owned your fair share of classics you know what I am talking about. My wife could smell a hint of fuel mixed with my cologne.
So why did we choose to go the LS route? Well it is a combintation of things. The ease of drivability, a better more earth friendly motor by having better mpg's than a carb'd motor, and it was a bucket list thing to do for me. What spearheaded the swap was when the original powerglide transmission gave out on me. I thought about upgrading to a 700r4 transmission and call it day but while I was in deep thought. I started to think about how I can build the Chevelle into perfect cruiser. The popular LS swap ticked all the boxes. When I was in highschool back in the early 2000's the LS1's were the top dogs in the muscle game. The one popular car amongst the car people I knew in the era was the 98 to early 2000's Chevrolet Camaro SS's and Corvettes. The LS1 was the one not the two. I would read articles on Super Chevy of swapping the infamous motor in classic Chevys. It took alot of bread to do a swap and the aftermarket support was limited and not as big as it is today. Back then I didn't have the budget or resources to do swap. I have been blessed by working as finance mgr with Toyota, and the network created by working as a Sushi Chef in my twenties to have met great people in the car world to help me navigate towards a small build like this.
