      If you are not worried about A/C, I'd even look at the under dash heaters like you see in the old CJs and broncos. They are stupid simple, and actually flow pretty darn good. One of the other things you could do to help is relocate the coil packs. A lot of hot rodders do it to clean up the valve covers to look better, but you could do it to help with the clearance issues. I believe holley or someone makes a kit to bring them almost right above the intake manifold

      School bus heater for you!
      We used vintage air in the 1949 Ford F1 project, all stuffed under the dash and works very well for heat/defrost

      My heat is always on defrost (i think my cable detached) so its no big deal.

      Comp cams also recommended the same exact cam grind as Summit. COMP Cams: LSR™, 265LR HR12<BR>Very Strong Torque & Excellent Response

      I have thought about relocating the coil packs, If it becomes a problem i will relocate them with a custom coil harness... I can build them for free at work with a few of the stock engine harness' that we have in the parts department.

      This will be a great thread. That's why they make ice cream in many flavors...same feel, different tastes. :)

      Look forward to the updates!

      Im with you...I hate them as well, but you could get a better judge of space after you install the engine/trans/TC.

      I added 2" to my SAS project, Im glad I did, there are places with 1" of clearance I was happy to get, which made the job much easier!

      Well i went up to STL for more of GMs "Training" and met up with a guy that had a stock LM7 camshaft that i was going to pickup for pocket change, and i almost walked off with it, but noticed one of the lobes had a pit in it o_O it looked like the roller lifter had turned so i passed on it.

      I know a lot of people will say to put an aftermarket cam in it while its out, but with two projects waiting for this motor to go in (A/T going in Bail-Out) i am just going to throw a stocker in and get it tuned....

      On tuning, the GM training instructor in KC does TONS on high end swaps on hot rods and can tune the factory PCM for me... hopefully for cheap, while i am up there, now i just need to get my Service Manager to get me to a class up there.

      So for reference. I measured the 4.0/a4ld/BW1356 and it is right About 67" thats using a precision eyeball from the crank pulley to the companion flange of the X-case.

      The LS\NP435/D20 is right About 63" from the water pump snout to the mounting point of The U-bolt on the D20.

      I am hoping I can use that few inches to my advantage (that's what she said) when positioning the powertain in the truck.
