I'm thinking of converting to a roller cam, (when I get some money) and I have some questons. I need a cam close to my current cam (comp cam's 280H (230* @.05 lift .494 total lift- the old grinde- you know the one from the early to mid 80's)) so I dont have to get a new chip for my computer, and I need to know what the advantages/disadvanatges of hydrolic roler and solid roler lifters and some Ideas on wich brands are better then others

 

Roller cams are good for several reasons...less friction at the lifter surface, ability to run steeper lobe ramps are the two biggies that come to mind.

Solid lifter cams, roller or otherwise, require frequent maintenance in the form of valve lash adjustment. The upside is they resist valve float...lower mass in the lifter, no chance of lifter pump-up as there are no hydraulics.

Hydraulic roller cams are a good compromise. You get the steeper lobe ramp capability (valve gets to max lift faster) but the same low maintenance of a hydraulic cam.

Just some info to help you decide, only you can determine which is right for your case and what you want to do w/ the car.

 

I'd have a tendency to say that Comp Cams make the best camshafts because of their quality control and machining tendencys and tolerances. It's just my opinion but they make the best camshafts.

 

any suggestons on peticular parts, detirmaning factors are cost power increace and compatiballty with my current computer(even though if I wait til I get a supercharger I can put a real lumpy cam 'cause I'll need to cange chips anyways)

 

btt

 

it involves changing the overlap and LSA and that could prevent the motor from going closed loop regardless of chip used.

 

There's yet another angle on kevinc's debate on hyd vs solid


And this is rev kits for hydraulic roller cams

They can be good for another 500 rpms, maybe more

So now you can push the limits of a hydraulic roller (6000rpms) to maybe 6500-7000


Although when it comes down to it if you want those R's, just go solid.

 

If I use solid, will I have to ajust them all the time - I mean there would be hardly any ware 'cause of the roller right? (by the way I'm going to have to wait about 3 or 4 months befor I have enough money to get the parts plus I'm trying to decide if I should get roller lifters, a supercharger or a paint job)

 

I believe the proper interval is about every 5k miles

Its not so much wear as it is the locks/nuts backing off a bit
