Hello everyone I just bought a 1983 grandprix and am halfway through stripping it down. I have been a g body enthusiast since 1997 when I bought my buddy's 87 two tone with t-tops in high school. Since I was a poor gear head back then I had to sell my 87 for food and rent. But years later I now have the 83 looking forward to advice on how to install the pontiac. 400 I have acquired for it . Any suggestions are appreciated also can't figure out how to upload a picture
