Sportsman Steel Roller Tip Rocker Arm - PRW 0845501 - Fits Pontiac 287-455 & 4.3L V8 (1958-81) Review

Thanks to my knowledge gained in practice, I was expecting a lot more from this product. However, I was extremely disappointed with its overall performance. The only pro I can think of is its compatibility with various car models. On the other hand, the cons are numerous. The product's durability is questionable, and it fails to deliver satisfactory results in terms of speed and power. Overall, I would not recommend the #PRW0845501 to anyone in need of high-quality engine parts.

There were those on the Pontiac 461 and they haven't even driven 2000 miles. A conservative combination of engines and revs never exceeded 5500 rpm. Would never recommend her.

This may be a quality product but I will not run them. They're only priced at £10. Spring pressure is greater than on my 400 Pontiac. I won't risk it if a hairpin fits in a $10,000 vintage build. I was never able to get the correct Pontiac 5/16 Rocker Nuts from the manufacturer. I have two sets of 3/8 nuts that will not fit any Pontiac I have seen in 40 years. I bought good old stamped steel rocker arms. You know, the ones that got that engine running for the first 50 years? No needle. No…
