Just what the world needs now...another heat stove thread. Not even my first
. But I've thought for a while you could make a 4WD heat stove from a 2WD one, so tonight I put it to the test.
I had three examples in the old basement, none of which were particularly outstanding by themselves...two were pretty crummy. One was a 2WD with the rearward down pipe bend. The other was was a 4WD. The third is I believe a 4WD example, but without the aft cutout. All are non-A.I.R. versions. Neither of the two 4WD heat stoves ended at the same spot.
I have often wondered if they only stamped 2WD stoves and then just cut them. I have seen 4WD versions that were cut with an upper and lower "tail", or just an upper "tail" as pictured here. Though I can't be sure than mine hasn't just broken. I assume this cutout is clearance for a 4WD dipstick.
There are two half circles on the inner aspect that I used as a reference. Two pics show this point compared between the 2WD version and one of the 4WD versions.
Here are some additional links for the curious...even one to a reproduction heat stove for 76-80 Corvettes which is similar and probably workable for us:
