Hello kind Sir,
I have a couple of questions. I understand you are using a 5.3 gen 3 motor for the build and you have an ls1 intake on the 5.3
Did you have any trouble fitting the intake between the heads? did you have to make any modifications to the intake for it to fit? are you using the stock heads?
aside from switching the water pump, accessory brackets, oil pan and intake was there anything else that had to be removed or modified on the 5.3?
what about the fuel system?? where you able to keep the injectors from the 5.3 to use with the ls intake??
is it cost effective to use a 5.3 for the build? I understand that you cannot drop a bone stock 5.3 because of intake clearance issues and because the accessory drive does not fit into the engine bay. by making the adjustments to the 5.3 will it still be cheaper to use 5.3 than to pay 2-3 k for an ls1??
Im deciding what to use, 5.3, 6.0 or ls 5.7.
Your response would be greatly appreciated. And good luck on your build
