Not Ranked
Hi craigayl,
The reason I changed the cam, lifters and valve springs was on the advice of engine building folks.
Presumably the high lift of the 514's cam at .647" was giving them heartburn in a street engine. More than one told me I'd need to expect to change the valve springs every 3 to 5 thousand miles, not to mention setting the valves at least that often.
Since mine's going to get some street use above those mileage figures (I hope a lot more!), I thought I'd try for "maintenance reduction" by going hydraulic.
The highest performance hydraulic cam turned out to be a hydraulic roller setup. Since a lot of production engines have used this, I'm hoping I made the correct decision!
Fingers crossed, and fire-up a month or so away,
Tom
