does anyone know which blocks (455) after 1973 had a high nickle content (block code). what are the pros and cons of a high nickle block? please help uzzled:
I know that 76 is supposed to be the strongest block to get. No word on other Pro's or Con's though. o No: - Freed
Pros & cons Pro-Stronger block Con-Higher manufacture cost. Buick thought it was worth the extra $. 75-76 blocks are stronger because they are a tad thicker in certain areas.:bglasses:
