360 balance ?s

Good to hear, I should not have assumed you already pulled the belt and started it to eliminate pulleys, fan and such.
That is one sharp looking van, reminds me of high school when a good friend of mine had one,his was a 79, had a 360 4bbl with headers in it, sum bich would haul ***. Was a lot of fun... many a late night, many a party... he had tear drop side windows, a bed, shag rug, fridge, crazy stero with I think 10 speakers, really decked out nice, paint was metalic brown, had a lot of fancy wooden hand crafted stuff in it too, between the partys and the girls... man... crazy days.
