Got the van mileage up to about 15.5 mpg with the old /6 3spd manual. was actually happy with that, but had a plan on freshening every thing up and swapping in a 904. Has been a lot of work and $$$$ Have mostly all the bugs worked out, been road testing and it's running just as sweet but the auto made it more simple to drive ,especially for my wife ! We plan on a few trips to the smokey's and then maybe out west with bike in tow. One of my biggest concerns was a shifter for the 904 . But after installing it I just used the original 2-3 shift rod on the column , perfect length and bends to fit the 904,just reverse shift pattern . I can live with that. Had to work out the kickdown adjustmet ( thanks to you guys who replied to my post on that ). Haven't run a mpg on it yet, expecting a little less with the auto,using an Oregon Cam regrind that was recommended by a couple guys here in the new engine build along with milling the deck and head a total of 80 thou, .30 over on the bore, head all rebuilt with hardened seats. Spent more on this slanty than I used to build my big block race motors, Crazy.
