  1. hi i wanted to do 390 swap about five years ago, did not happen because of life... what i do remember is there is a bell housing to fit a t56 and a dry sump oil pan involved. if you set the motor under the hood on the ground (on stock oil pan) and try to shut hood, you will see why you need a dry sump. as for power you need good heads, large carb(efi is better), good manifold, 10-to-1 compression, cam (if you use efi you can get a mean cam and have it run good). i do not remember all my build specs, but i started on that motor in 00' and it was 3-or-4 years to find all of the parts at any kind of a deal. today it will be real expensive to get close to the power this motor is capable of. by the way my motor ended up rear wheel dynoing 487 hp and 512 ft lbs good luck.
  2. Thanks for your advice grumpy! I have a lot to think about and will contact you if i go foreword with the 327.
  3. Hi grumpyvette. I have read all the 327 posts i can find and i cannot escape the thought that it might be a waste money to rebuild this motor. Block #(3892657) bored .040 over, 10 to 1 comp. flat top pistons, has 1.94 camel hump heads #(3890462), old torker manifold, the cam i think is called a "purple cam" 350 horse, holley 650 vacuum secondaries. The block is bad (water in the bore and rusted) so i need new one. Heads need hardened seats/valve giudes. I have a 73' 240z thats striped inside, want to use a t5 trany to keep price down and i am looking for a diff with a 3.9 ratio. Also i want a ruff idle and more high end power than low and i am thinking of using 180 headers. Is worth it for a 350hp small block or should i go buy a crate motor like a zz4. My budget is 5k for motor. Thank you for your time!
