Ok rebuilt my Holley spreadbore today and dropped the tank. Gonna drain tank and report my findings tomorrow. Also the spark plugs are fowled and the tranny is leakin like a sive so might just pull engine and tranny and regasket everything. And go through it all. Also need to rebuild the rearend cause the axel seals are leakin. And might change to 11 inch rear drums while im at it.
