Second Generation doghouse info sought

Wondering if all second generation vans have the larger doghouse and are they ready to accept a V8?

I am looking at a '68 with a straight 6, but would want to upgrade the motor at some point. Is it doable?

What Don has posted is the cross flow system that is used with the V8. If the van your looking at is a I6 and has the down flow radiator it won't have the upper and lower mounts or the surge tank. The down flow radiator mounts with flanges on each side and there's sheet metal on each side in the doghouse that it mounts to that isn't in there with the V8 setup.

i HAVE A ORIGIONAL 1967 GEN -2 CHEV VAN- 283 & POWERGLIDE- IT DID COME WITH THE DOWNFLOW RADIATOR!= TO MY KNOWLEDGE ON THESE 2ND GEN VANS- 68 & UP ALL CAME WITH CROSSFLOW RADIATORS (parts listings) .Ill also add that all 10 bolt rear axle ratios 67& up were optional on gear ratios- yet most dealers did select the 3:08 & 3.36 ratios yet all were not posi types - that also was optional. Mine came with a posy 3:73 -1 ratio.

What twinpilot said. The 67 was a changeover year and in some instances (parts used) are kind of on their own; where the 68 to 70s are all more or less the same.

So what your saying is that 68-70 with an I6 has the cross flow radiator?

67 to 70 came with down flow or cross flow. all I am saying is the 67 can not always be grouped in with the 68 and up, it has similarities mostly but also some differences.

exactly!!=many diff mfgs-of many lines of autos/vans were required to change certian parts due to safety concerns.Dual masters, dash pads & even some were still optional-due to change over datse too-allowing use of parts till used up until certian dates became mandatoy. I have never liked the deletion of vent windows and the high beam switch relocated to the steering column=yet i believe were done to cut production costs! look at the use of metals , chrome & such versus the plastics still in use today. being an old fart= =i can still remember going into a dealership-& under 21 ages too & ordering a new car -buily with all the options i wanted - delievered in usuallt 90 days or less & putting a $100.00 deposit on it to get it started!! COD & the total costs was under $3000.00 AHHHHHHHHHHHH-The god ol days . Thats before we ever had anything called ="Credit Cards"!!!!!!!!!!!!!! And there wasnt any national debt either!!

Does anyone know if they produced any second gens with a I6 that came factory with the cross flow radiator (not special ordered that way)? The only second gen's with I6 that I've seen had the down flow setup (my 67,68 and nightmoves 69).

My 67 parts van has a crossflow in it. It is a factory powerglide. I understood all autos in '67 used the crossflow??

My 67 was a powerglide, I6 with the downflow.

68 to 70 V8 came with the cross flow. I have only seen the down flow in I6 vans of all years 64 to 70.

Another tread some time ago reported that the 64 to 67 came only with down flow including the 67 V8 van. the 67 had some oddities as a change over year. the 67 only came with the 16 gallon gas tank like the first gens. the 24 gallon tank started in 68.

my 70 parts van had a factory 6cyl,powerlide with the crossflow setup. Bill

I think between Bill and Don, those two have seen more vans then everybody else all added together.

So some 2nd gen vans came with Cross flow rads and 6 cylinder. Any ideas on how that is or can be distinguished from the down-flow 6 cylinders?

I am always on the hunt for parts vans and cross-flow dog houses and such but I have been ignoring L6 vans believing they were all down-flow.

I agree, the upper radiator support being welded in would be a good indicator of a factory install. Seems like there is always something new to learn about our old vans.
