Hello: I just ran across this forum while looking for a 2dr. 1958 Oldsmobile Fiesta wagon. I'm a retired G.M. Supervisor, ex drag racer and 1958 Advisor for the National Antique Oldsmobile Club. I drive a 1941 Olds Phaeton 4dr. convertible, one of 6 known to exist of the 125 that were built. I also have a 1958 Olds Fiesta Comet coach ambulance, 3 Fiesta wagons, 2 are hard top parts wagons and a sedan wagon that I'm building as a tribute to Oldsmobile. The tribute "Oldscoolbus" is built with 88 to 98% all Oldsmobile parts available between 1957 thru 1970 the years of my performance youth. The chassis is an original air ride suspension available on all 1958 Oldsmobiles. It is powered by 2 engines. Under the hood is a 1957 371c.i. NASCAR W1 solid lifter J2 tri carb motor mated to a synchromesh 3sp. manual trans that drives the 1970 W27 aluminum center section rear axle. That assembly is moved forward 18" to clear the rear engine drive wheels. A complete 1969 Toronado drive cradle is grafted to the original Fiesta frame rails. It contains the 455 c.i. rear engine with the only 1967 L69 tri-carb intake ever factory cast. The air cleaner is a carbon fiber version of the 1966 W30 ram air shroud complete with 4" air inlet hoses. Chased parts for 15 years. Should have it finished this summer. Dr. Oldmobile
Wow that sounds like a great endeavor. Fannie is right, we all love pictures around here. If you go to the Garage section - https://www.stationwagonforums.com/forums/garage/ - you can add your wagon there. I'm sure everyone would love to see it. Welcome to the forum, we are glad you are here.
Although I was able to read ever word, it sounds like another language. I am not a mechanic but I can usually follow along most engine talk...but this... This did help some but truth be told I'm a bit more confused. However, I am impressed and applaud your talent and desire to create something VERY unique. Looking forward to seeing your progression. Please keep us in the loop. So glad you found your way here.
To be safety compliant, there has to be a firewall between the rear engine and the driver. That component has been changed 3 times. The first version looked like a pickup truck. The second version used the three-piece rear window from a 1957 Olds sedan that would eliminate any blind spots with the rear view mirror. That one proved to be too wide to fit between the "B" pillars. The third edition is a combination of the two that might require the lift gate and the tailgate to be joined together to make it a one-piece lift hatch. A little more "Air build" engineering is needed to make that happen since the rear half of the roof pivots open 42" to expose the rear engine for maintenance.
