Good day all I have a 440 block with the "452" MP aluminium heads,and now i need to order the camshaft ,pushrods and the rocker set. Wich could be a good rocker set for these heads for a reasonable price? Since it is going to be a street car i think that i,m going to order this cam: http://www.summitracing.com/parts/CCA-CL21-227-4/Thanks a lot for any input.

Lots of choices. The Comp Cams "pro magnum" cast alloy steel work very well in your application. They are robust and don't have fatigue issues and generally have excellent sweep over the valve tip with no adjustment. They also work well with the stock oiling setup. Get the matching shafts and hold downs to go with them.
Another good choice are the Crane ductile iron rockers that are going back into production I understand. Similar benefits, just a little more weight to deal with.

Thanks a lot for the replies, Then ,is not necessary to install aluminium rockers? I always heard that install an iron set up on aluminium heads is a botched job.. About the cam ,it was suggested to me like a good option for my intention,wich is to build a strong street car with a good low rpm torque.Nothing for the track. That is why i,m considering to order it,in fact i didn,t look much more

That sounds like a good street cam but make sure you check your piston to valve clearance I am using Isky iron rocker on Indy EZ heads and they are working great.The cast iron rockers will sometimes gall on stock type shafts.I recommend hard chromed shafts with whatever rocker you choose Gus

Thanks Gus, I,m still waiting for the alu heads,i ordered them to summit,and they use to take 3-4 weeks to receive them from the factory. However the pistons are flat top,stock type.The piston at TDC is around .05" under the block surface and the gasket is going to be 0.039". Until now,this engine was running 906 heads(87cc) with this cam: http://www.summitracing.com/parts/CCA-21-248-4/So i hope not to have troubles with the new cam... Thanks again for your invaluable help

With what I have learnt ( not personal experienced ), the cam it had is too much duration for the compression on 87 cc and composite gasket... SPECIALLY on a street car. Beside will be requesting a HIGH torque converter stall, even more with the low compression ( it looks around 9.3~9.5:1 )? Dunno what the last owner was thinking when build that staying below 240 at 050 will be more healthy. Maybe close to 235 max, so the first one you posted looks waaaay better option

Hi Nacho, The engine was "Performed" by Arrow Racing in Michigan. I have a several sheets and documentation about this engine.The last owner gave me all this stuff with the car. I didn,t like how it was running.It was almost impossible to burn tire under acceleration. Regards

Hi,thanks for the reply and sorry for the delay,i have been a little busy these days. To mount the existing rocker arm is not going to be an option since the other day i noticed that one of the rockers is different .It is shorter than the other ones and i don,t know how it was working ,because it does seem that i can,t arrive to the valve. Uploaded with ImageShack.usUploaded with ImageShack.usDue that i,m pretty sure that i,m not going to be able to found one of those Isky vintage rockers for replacing it ,i,m considering to order this harland sharp kit,because it does seem to have a good price -quality relation- ship: http://www.summitracing.com/parts/CSP-S70015K/What i don,t know if i will need more parts for installing it...

From the looks of it either Arrow screwed the customer or the previous owner screwed you. Those Isky rockers are good rockers ... I'd try to complete the set if I were you.
If it comes down to it, there is absolutely nothing wrong with running two different brands or types of rockers as long as all intakes were the same and all exhausts the same. Your bad one looks to be an exhaust so you could buy a set of aluminum exhausts and use all the Isky intakes. The motor will never know the difference.
No matter what you do, get rid of those springs and use spacers and replace those factory hold-downs with something else.
