I'm on the market for a restored 78 or 79 Bronco and I haven't seen one with a 400 and a 4-speed for sale. I've seen plenty of 351's with a 4-speed...even a couple of 460's with a 4-speed. My search has gone on for about 8 months and I've been surprised at the apparent lack of this motor and transmission combination. I regularly check the usual sites (eBay, Craigslist, KSL cars) and a few classic car dealers. Is this issue common? Anyone have some insight or other places to check? Thanks.
