Do the 93-97 LT1s have hydraulic roller camshafts???

 

Yes. However, make sure the camshaft your chooseing is for an LT1, of your car year, cause they have a dowl pin that runs the opti. And I think 95+ the pin is longer.

EDIT: sometimes the dowl pins will be to short, or to long from the factory and will need to be machined or "tapped in". If you do not match the pin lenghts, you could destroy alot of opti's before you figure out the issue.

 

I was on edelbrock and the number is 2108.

They have a package you can buy that the parts are supposed to work together but i get confused because it says the Valve Springs are for a Ford Motor-it doesn't make and sense to me because its for 390-460 ford motors which is way bigger the a 350. So what the deal?????

All of the parts in the package are as follows:

Intake Manifold: 7107
Throttle Body 2 options I chose:3810 Because it's bigger.
Cylinder Heads: 61909
Cam: 2108
Lifters: 97384
Valve Springs:5767 It says to pick these but wouldn't the heads already have valve springs on them-its says complete next to the heads. And what about lifters would those be on there too?????

 

Don't waste your time and money on that Edlebrock package.

 

Not sure on the valve springs, I can't anwser most of these questions but I can tell you this. 99% of edelbrock stuff for our cars is not worth buying.
Id look a different route personally maybe look into elliotportworks for heads and cam package, reuse your lifters, keep stock Throttle body or go with 52mm.

 

Why wouldn't you buy Edelbrock????? I still think i'd go with a 58mm.

 

Its been proven several times the edelbrock parts for our cars are not the best route to go. If you read alot you will see no one uses edelbrock parts, unless they need a replacement intake manifold (the air gap). I am sure someone has some hard evidence and will chime in. That way you are not baseing your buying decision strictly off an 'opinion'.

 

What else would you recommend?????

 

Lloyd Elliot or AI. Both will do MUCH more for you than crappy edelbrock.

How would it destroy them????

 

If the dowel pin is too long and bottoms out in the hole in the Opti, it puts pressure on the back of the Opti and forces the rotor forward, where it rubs agains the cap. Also forces the slotted disc for the optical sensor forward, so it rubs against the sensor housing. Can damage the bearing is well.

 

What if its too short then what does the opti not work???

 

There won't be enough of the dowl to engage and rotate the opti rotor.
