We get a bunch of calls and emails every week about what is needed to make these swaps run and what works and does not work. Since there is already a ton of false info out on the internet about these swaps, I'll try to clear up the Myths and Factoids out there.
My answers are based on the 47 (as of January 2019) vehicles we already have on the road. Below is original content. Nothing is a repeated myth from the internet or a magazine article. We've applied and tested each answer given below so we know it works.
One Example is the 34 Ford on our home page. It was swapped with a L83/6L80E over two years ago and has logged nearly 20,000 miles on it since the swap was completed. Not only is it our customer's daily driver, it's been driven from Florida to California and Tennessee so the swap is proven. It went through the mountains, through 120 degree heat in the desert and has been in freezing temps without a hiccup. Note: This vehicle uses a Walbro 255 LPH fuel pump with a C6 Corvette Fuel Filter Regulator Combo just like an LS Swap. Don't be fooled into thinking the L83 needs 75 PSI. This one was dyno tuned by Jeremy Formato at Fasterproms and is running perfectly with just 58 PSI for over 2.5 years now without a hint of fuel starvation at this pressure.
This list is not all encompassing but as the questions come up I'll post them and the answers based on what we know works. - Ken
