Rebuild Question

I have an 86 K-5 Blazer currently with a 305 in it thats getting a little tired in my garage I have a 350 block casting number 3970010 with a set of heads with the casting number 462264 I also have all the pulleys and necessary items to install this motor including a street dominator intake and the holley 670 cfm carb with electric choke the blazer will have a rebuilt 700R4 tranny and converter put in not sure of stall speed i will be using headman long tube headers. I am trying to find out what would be a good build up to tell the machine shop to do as far as I know the block has never been rebuilt the piston that are in don't show any marking except for either a G or an H I also have already installed an Auburn Posi unit with new 3.08 ring and pinion gears I was thinking of one of the 4X4 cam or Rv cam but don't know which one the truck is driven almost everday but primarily for the towing of my 69 chevy or 72 Monte Carlo. All suggestions welcome!!!

A edelbrock performer plus would be a good RV cam for your application. but comp cams and others make cams just for the 4X4 line which are also excellant. The heads are light casted crack prone, so I wouldn`t recommend the use of them. You`ll need a older HEI with vacuum and mechanical advance since the computer will no longer be functional. since your using a auto tranny, you`ll need a painless wiring kit or the like to control torque converter lockup, and I would also recommend a external tranny cooler especially since you tow. the intake and carb are fine to use, if it were me I would use a 600cfm carb. a 383 would be even better for what your purposes are, you have a fairly heavy vehicle and you use it to tow so it needs all the low end torque it can get, so I`d focus my build on that. Your machine shop will tell you what your block needs.

The 86 K5 is not fuel injected or has no on board computers to control fuel or anything so will I still need the painless wiring kit? The vehicle already has a working 700R4 and has a 4bbl quadrajet on it.

Sorry I forgot to tell you it also has an Hei ignition system with vacum advance with I upgraded to the super HEi accel coil and wires and also upgraded the ignition module to the petronix piece.
