UPDATE 2022: After 2 years of the most abuse you can put on a set of rocker arms – I’m happy to announce these rocker arms are holding up perfectly!
I have these in my 455 stroker Pontiac powered jet boat as seen on my spotts performance website and you tube. This boat sees high rpm at very long periods.
Make: PONTIAC
Engine: 350 400 428 455 or 67-79 Pontiac heads
Mounting Style: Stud
Rocker Style: Roller
Ratio: 1.6 Ratio
Stud Size: 7/16″
Material: Stainless Steel
Includes Polylocks: YES!
Quantity: Sold As Set
Stainless steel material for superior strength
Extra large trunnion for increased durability
High rpm stability with no deflection
Large roller tip for less wear
Full needle bearing trunnion for increased horsepower & quicker response
Kit includes poly-locks
Stainless steel construction and extra-large trunnions give these roller rockers superior strength and increased durability while eliminating deflection at high RPM. Each part’s full needle-bearing trunnion allows for increased horsepower and quicker response, and a large roller tip helps prevent wear.
Keep in mind your cam is increased with 1.6 ratio rocker arms – make sure you have enough clearance.
1.6 ratio rockers may need elongating pushrod holes usually over .530 lift – always check clearance!
will fit under stock valve covers when used with my RAS4 rocker studs – see my other auctions
Not recommended for solid roller cams
works with factory iron, Edelbrock, KRE and other aftermarket Pontiac heads
see my other auctions for 1.5, 1.65 rockers, lifters, pushrods and other Pontiac parts
