The horrible compression ratio and crap heads are what’s hurting this set up. Putting a cam in it with heads that will only choke out any performance gain you would of gotten. Big block like to breathe and those heads are like you breathing threw a straw. A turbo would help. The low compression will work with a turbo and the air will be pushed threw. With a turbo you have good driving majors and power when you need it.

Have you done many BB turbo setups? I would just be worried with all that extra power a guy may have problems with the driveline. What's your experience with that? I am very interested.

You’d need one with an anti ballon game plate. If your gonna do it with a 10 bolt id go with an 89-91 Burb or Blazer rear axle and if 4x same years 10 bolt front axle too. They make carb kits to convert a Holley to be used as a blow threw carb. I wouldn’t use a Slobberjet or Edelturd.

I had one of the 700r4 in my 86 and I had problems with that and that was just a 305 with an RV cam. Nothing special.
Good advice. I have big blocks in a couple of my rigs so I know what you mean.
