Those of you who have done an LS swap on your chevelle, what do you wish you knew then what you know now? Do any of you have build sheets or a list of necessary parts? I havent taken the dive on the motor yet but I want to start doing as much research as I can prior to tackling this project.
I wish I knew that the Dorman 615-901 intake manifold did not like ev1 injectors or LS1/LS6 fuel rails...Go LS2 for both.
I wish I knew how important it was to get the right swap plates...get LSX Innovations and use the 1 3/4" forward bias to run a 4l60e without cutting and using stock 350 cross member in the stock location
I wish I listened to all the advice I read about staying away from those awesome looking sheet metal intakes....Just don't do it, they really are junk (and dangerous).
I wish someone would have told me to take my time and measure, check measure when installing the power steering pump. In order to get things to line up using aftermarket brackets, sometimes you have to shim the pumps back a bit and press the pulley on a little farther than stock. I went through two water pumps and three pulleys trying to get this right on my first swap....Measure and take your time.
I wish I didn't spend the money one braided steel an 6 lines.. They are a nightmare to work with. The black mesh type are fine.
I wish I had a Holley Terminator Max system for my first swap....I went with the ebay reworked harness and the mail order tune. Harness was fine but the mail man special tune (aka basic car spec and VATS delete) was not good. Terminator Max is amazing! I've never tuned a car before and I'm able to dial in my Chevelle to perform to my liking with ease.
I wish I changed the rear main seal when I was doing the cam swap and everything else.....I haven't had any issues with it yet, but I think about it all the time.
Last, I wish I would have established a realistic budget and timeline for my most recent build. Even though its my second, I forgot about all of those little $20 and $30 parts and pieces that you need to make stuff work sometimes....As the saying goes, it comes down to Good, fast, and cheap and you only get to choose two of the 3...I chose Good and fast, and it damn sure wasn't cheap!
