4.25 out of 5 stars91 d150
miller, d, 12/30/2002
1991 Dodge RAM 150 2dr Regular Cab SB (3.9L 6cyl naturally aspired 4M)
3.9 v6 with 130000 miles had no ring
grove. some dummy cross threaded a plug
in the head. my only gripe is it needs
more guts. easy to maintain. will
outpull any 4.3 chevy on the market
