the frame and axles are strong enough for the power but the suspension will be upgraded. I have a 550hp 383 in it at the moment.
I will have to disagree with you on this one. I pulled 20,000 lbs in a 4500lbs 3/4 ton chevy that has the stock 245k mile 210hp 350 in it. I understand that I didnt pull any real hills while doing so but it pulled it and with rpm it would hold speed ok. Understand that I did this with what I had not some purpose built pullin rig. Bet me the money it takes to build the truck and show me the grade, Im your huckleberryBuild the nastiest small block your wallet can muster, put any tranny you want behind it and any rear end ratio. Put it in a 7000 pound truck and tow a 10K trailer up a steep grade for 20 miles at 65 MPH. You won't make it.
Im not ignorant, Im crazy theres a big difference. I know what I was doing wasnt safe but that wasnt my point. My point is that torque is torque, I dont get were people think that a sbc that has 400ft is less capable than any other engine with the same numbers. I understand that you might have to pull some Nascar stuff and hold the sbc at 7,000rpm to get the desired affect but with gears its possible, and I know it.Ignorance is Bliss, isn't!!! :rasta:
Pulling 20000lbs. behind a light framed tk! blow a tire on anything and you will be a Huckleberry
