I have a 71 C-10 2wd that I have had a Pontiac motor in for years.I used to have a low comp 455 with 3.73 gears and you didnt even have to open the secondarys on the mountians towing with it.I now have a 77 Gran Prix 350 in it which has been used for towing for 3 years.It is bone stock with just an old 70 iron Q-jet intake-headers, a 400 turbo and 3.42 gears.I have an open trailer that I tow with and just this year I bought a 20 ft.enclosed trailer that I haul my Trans Am race car in.I made my own motor mounts but it is a fairly easy swap.I love it and it gets more attention at alot of events that my race car.The 350 is getting a little tired so I plan on a 455 swap back in this winter.The truck ran a 14.52 in the quarter with the 455 years ago-thats thru pipes and with slicks.It was just a 73 455 with 068 cam, 76 6h heads to keep comp down to run on todays s__t gas.It now runs 16.2 with the 350 and has filled in a few racing rounds in the Outlaw Pontiac Drag series last year when my race car broke-you are allowed to run a pontiac powered anything.It just tows fantastic and I cant say enough great thing about the swap.You will be proud to open that hood when you get it finished-I say do it!!!!Let me know if you have any questions or I can help in any way.I can send you pictures if you like.Good luck.
