I have thought about adding some roller rockers. I saw jegs sells the crane gold race extruded billet aluminium (part # 270-10751-16 and 270-10758-16) and claims that they are 50 state legal. Should I go with 1.5 or the 1.6 self align(what does this really mean anyway?) I want to know if it is worth the money or do I need a cam first? If so, which cam?

I am very confused

**they have to be smog legal parts**

am I wasting my time? should I just buy some headers first?

The plan for the car is to have a nice cruiser with some good power.


Thanks in advance

 

1.6 will in effect make it act like you have a slightly larger cam.
Personally I would stay away from aluminum on a street car. Aluminum tends to bend/crack/get weak. I chose stainless, myself.

 

okay thanks for the info.

 

Ive been running my Crane 1.52r roller rockers with no
problem at all. Yes, they are aluminum and will wear out
at some point. But I had gotten a great discount on them
and had to go with them. I wont expect them to wear out
for another few thousand miles. Then, ill opt to go steel
if needed.

Self-aligning is exactly what it states, the rocker does
not need guide-plates to keep it from wobbling off track
or having a pushrod bind up, what have you.

There are benefits to both, but you dont need shaft
mounted rockers for a motor of your tolerances.

But, It would be cool if I had some

 

I have been running the summit 1.6 aluminum ones for about a year. Its my daily driver and I beat the hell out of it. No problems for me. They also are pretty. Unless your hitting extremley high rpms the aluminum should be fine.

 

okay, thanks everyone for your input. It looks like I'm gonna go with the steel. Still don't know if I should use the 1.5 or the 1.6, what do you guys think I should get? How long will the steel rockers last?

The car has 69xxx miles and is driven during the summer months.
