the 220hp engine is called (RPO Code) W72. its the same L78 with GM mods.
Pont cid350 6X-4 heads were used. the cam was changed. better oil pump. and the timming was changed. it went from 185hp to 220 ish
the W72 started in 1977
my shaker is the low profile one. only used on the TA for 6 months or so.
not rare, just harder to find if its the one you need.
