The engine is sold. I'll soon have a very fresh 901 w/ an "H" gear for sale as well as some other goodies soon for those planning an SBC conversion. I couldn't do much with this sitting in my garage as it already is stuffed to the max. Therefor I felt it somewhat necessary to sell this before commencing with the re-conversion. I've been silently (yeh, I know; me silent) working in the background for a few months fabricating some items that will be needed. I'll do my best to document things a bit more accurately than the previous conversion. Once again I'll be using the Subaru 6 and Subaru transmission. I've had tremendous success with this platform so I might as well repeat myself. So sit back, bear with me and watch as I stumble along and occasionally embarrass myself. Mistakes are an integral part of my journey. (IMG:style_emoticons/default/beerchug.gif)

The steel spacers or bushing stock arrived last week so I was able to complete the engine cradle sans the transmission hanger part. Now that you know where the center of the front hangers are the next step is to drill those 1/4" out to 3/4". Since the arbor bit has a 1/4" pilot bit we will use that hole to align the 3/4" hole saw before drilling. To make sure I'm not "catty wamposed" I position the tube so that the 1/4" bit, still in the drill press, so that it bit passes freely thru both sides before clamping the tube in place. Next I remove the 1/4" bit and chuck the 3/4" arbor bit in place. Now it's just a matter of running the 3/4" bit thru. If you're "on the money" the steel spacer will need a bit of persuasion to pass thru the tube. If it doesn't, no big deal. It just makes it easier during the next few steps as it will not need to be hung or supported on this end.
Here is the right side in place. The steel spacer is still 4" long at this point and will be cut down to 3" before welded in place. I know the picture shows to cut it 3 1/2" but that is incorrect. Now check the tube for level and adjust the tube up or down the steel spacer until it is level. Now check to see that the other end is in the correct spot on the 3"x4" plate. Once you're satisfied tack both ends and recheck for level and position. If it didn't slip or move go ahead and weld both ends as much as you can. You can finish any areas you miss once we remove the cradle from the car. Why do it this way? Shrinkage! I learned that lesson on my 1st cradle. By doing it this way we are using the car as a jig to prevent any shrinkage. It's a PITA welding overhead and in tight areas and your welds will look like (IMG:style_emoticons/default/stromberg.gif) but in the end you'll be glad you did. I think I'll make a jig for future cradles so I don't have to do this in the future. Oops doubled up on that last pic. Attached image(s) |
