Have repaired a cracked upper loop on a '69 Nodular Pontiac 8.2 housing, very valuable rear going back in a RA4 Judge. Cleaned the hsg well, then V'eeed out the crack with small diam die grinder cutoff wheel. We then heated the loop on the hsg with a big propane torch, then carefully welded the prev cracked area with high nickel rod/stick welder. After welding, kept the heat on the welded area with the torch, dinking the surrounding area & the welded area with slag hammer, slowly taking the heat off the effected area.
If the crack is all the way across each loop, & the '70 housing is just a standard gray iron 8.2 housing, I'd weigh the cost of having the R & P setup in another '70-72 Pontiac 8.2 housing. Gray iron center housing Pontiac 8.2's will have an alphanumeric date code in the lower webbing, nodulars only have a 3 digit number which is the Julian date tied to the specific nodular iron Pontiac 8.2 center housing.
