SNK-EYZ OP I Live Here Joined: Jan 2007 Posts: 10,132 A Red State	I'm planning on a cam upgrade in the 572 Hemi in my car and I'm trying to decide whether to stay with a hydraulic cam or go to a solid lifter cam. The one in the engine now is a M/Perf 524/292 hydraulic cam and it's just flat above 4800. The engine will never see higher than 6500 rpm. At the end of the quarter mile it's at 6200-6300. The car is mainly a street car that will get raced some. The cams I've been looking at on both (solid and hydraulic) are roughly 600 lift roughly 250 duration at .050 lift. Hughes Hydraulic cam Howards Hydraulic cam One of the solids is a NEW MOPAR PERFORMANCE SOLID LIFTER CAMSHAFT FOR A 426 HEMI ENGINE.PT NO P4529345. THIS IS IN NEW CONDITION AND READY TO INSTALL. SPECS ARE 312 DEGS DURATION LIFTS ARE .614"/.598" I've tried searching on here and mostly what I read is it's mainly a personal preference for the most part. What are the pros and cons of solid vs hydraulic other than the obvious of lifter adjustment? Kayse can't keep up at all now. lol

SNK-EYZ OP I Live Here Joined: Jan 2007 Posts: 10,132 A Red State	Most of the guys I've talked to don't like the short valve spring life of a roller cam because of the high spring pressures. I don't want to have to replace valve springs every year or two. The high price on the roller cam stuff kinda deters me also. I'm not trying to get maximum power out of it. It's a street car first and a race car second. There's always someone faster and being a poor retired guy I can't afford to compete $$$$ wise. I guess I'm trying to figure out if a hydraulic cam will perform decently up to 6500 rpms. A few HP isn't going to make any real difference to me for racing. As long as it pulls decent in the 5000-6500 range. If The solid is my better choice in that range I guess I'll go that route. I race to have fun, if I win great. I'm not going to lose any sleep if another car is faster than mine. Kayse can't keep up at all now. lol

What are the pros and cons of solid vs hydraulic other than the obvious of lifter adjustment? If you are never going over 5900 rpm, a hydraulic is fine. What are the flow numbers of your Hemi heads? What is the torque converter stall speed? A 572 cubic inch engine will eat duration for breakfest, so depending on CR, duration is your friend.

That MP camshaft in the 528, do you remember the RPM range? I'm screwing my 528 together now with a little 560 lift solid and I'm already considering going a bit bigger. I'd be happy to shift it around 5500 but it has to make steam too. Sheldon

At the end of the quarter mile it's usually revved to 6200 roughly. I don't plan on revving it past that but I want to make sure that the power curve is still pulling to at least that. The shift light is set at 5700 for now but it needs more cam to even pull to that rpm. Kayse can't keep up at all now. lol

Sheldon I don't see it as a hijack, the working rpm range is what I'm trying to figure out for mine too. The best mph so far is 117 but between the small cam and other issues it falling off badly after 5400 rpm (like a 50+ hp drop on the dyno). It tries to recover but only comes back up 1/2 of what it loses. IMO, It should mph higher but obviously it's "issues" are holding it back. I'm limited to a 28 inch tall tire by the rear wheel-well size. I kinda wish I had gone with less gear but with a dana it's not an easy swap. Kayse can't keep up at all now. lol

I have no idea on the flow numbers, the heads are out of the box M/Perf-Edelbrock aluminum heads. As far as compression ratio, the pistons are M/Perf-Wiseco 10.5-1's. The guy that built the engine did the math and came up with 11-1. Anyone else have any opinions good or bad on either type of cam for the rpm range that I'm running in?

They will need to know your combination. I am sure they know what the stock out of the box heads flow. The most important thing is to have a cam that will work with the flow of your heads. This will either make or break your motors performance. You can't just pick a cam by looking at cam profiles. It is a shot in the dark. Your gears and tire height should be fine. I'm running the same set up in a 528.

That information that they are giving you on the performance of the cam is not accurate. You have an almost 600 ci motor. These cams are for 426 ci and 500 ci. I would suspect the working rpm of those cams in your motor will be much lower. Call an expert and have all of you motor information ready.

Mark This is just what I was going to tell you. I also use Dwayne Porter as he speced me a cam to work good for my combo and I love it. I went with a solid flat tappet that he suggested I use and I am real happy with it. I know some guys who run rollers on the street and have their lifters checked and rebuilt every few years and have been ok but I also know a few who did not check their lifters and lost an eng. A good racer friend of mine just lost his Hemi race eng because a roller lifter came apart from a valve spring problem. So its something you have to decide if you want to go roller as some use rollers and they work great for them and some have had problems. I did not want to worry about solid rollers or check them every few years so I went with the solid flat tappet that Dwayne suggested and I do like it in my 440/493 street car that I drive alot as I just got home last night driving the 90 mile run home from Carlisle. Ran about 60 mph all the way home and it ran great. But I would suggest you call Dwayne as he is one of the best cam and engine guys there is out there and he will not steer you wrong.
