The undesirable gear set with the micarta (plastic) cam gear is best avoided - these were used during the mid-1970's - mid 1980's with the 250 and 292 (including the Pontiac Iron Duke which shared its design with the 153 with the exception of a cross-flow cylinder head and repositioned distributor while using some components from the concurrent Pontiac 301) in both passenger cars and light trucks. |
