roller tip rockers

Can I expect any noticable change if I use roller tip rockers on a stock 88 Corvette Tuned Port engine? How about 1.6 rockers? The car is driven daily and weighs 3700lb.

Comp Cams states a HP gain, but my experience is you will never feel it. I installed a set of Comp Cams roller tipped rockers on my Fastburn and really didn't notice any difference. Having said that, I feel they are worth the expense as it reduces a wear point and makes the valve train a little more durable. I obtained mine from an Ebay store and saved quite a bit over what Jegs or Summit wanted and they were new in a sealed box from an authorized dealer.

On a street driven car looking for a seat of the pants feel,more then likely nothing will change.

If you do decide to buy them get the Comp Cams...I have had some of the off name roller tips in my shop and the roller is big and not in the correct location and it will mess up your push rod geometry.. The comp cams rockers are spot on.

I have the 1.7 Crane's in my Ford 5.0 rather then the OEM 1.6's. I installed them for a couple of reasons - I went to a "bigger" cam and wanted all it would give me. Secondly, the Ford OEM rockers tend to cause side thrust wear in the valve system - guides and valves. And then, lastly, braggin' rights.

Will I feel the difference?? Most likely only in my mind where it counts most. It's a pretty tame engine otherwise

Dave,
When I raced 351 Cleveland motors, a neat trick was using a combination of 1.7 &1.6 rockers.

Bill,
Which rocker went on which valve? Clevelands are a different "beast" then my little 5.0 though might have considered it on the BIG 351W I ran a few years ago
