So in my opinion it can be done its been done 100 times over you would not be the first.I want to put a LS2 in my truck,dont know why i did not start yet well i guess i just dont want to cut my firewall,but time will tell.Go to truck photo gallires and look under 521,you will find a blue one with a blower sticking out of the hood.and another yellow one that has been done to.Also go to 320's and look at the cool red one with a V-8 under the hood with even a smaller engine bay.I do agree with the guys that we would hate to see you start and never finish and it becomes a basket case,but if you want to do it and you have the know how and the tools time and money you could it for less then a KA-24 swap.Remember a chevy V-8 would take a cheap fuel pump and 2 wires and it will run and even with the added weight instint 300hp.
