Came across an amazingly clean barn find elky and the price is reasonable- just hashing out the details. I have a 489 sitting in pieces that was going in my 1984 Cutlass, but I'm going to scrap that car and use parts from it for the elky. My question is how strong is the body of an ElCamino compared to my Cutlass? I have a bolt in 9inch for the back so the rear end is covered. I also have a well built turbo 400 transmission. What I don't know is how much the body can take. The engine will produce well north of 500 ftlbs of torque and hp will be around the 500 mark. It is a street oriented engine, not a race engine and the car will be geared as such. Right around the 3.23 to 3.31 ratio. I have 3.42s in my Cutlass with a 408 BBC and I'm not comfortable spinning the 489 that high at cruise. It will have plenty of grunt for a numerically lower gear. However, 1st and 2nd gear will still have plenty of frame twisting torque which concerns me. Am I worrying too much about this on a street car? Anything I should look out for?
