At one time or another I've run most of the hydralic and solid grinds from MP in a wedge. Once I went to a solid I decided never to go back to a hydralic.
Look at the thousands of /6's out there that have never seen a lash adjustment. My 528 hemi, reset the lash after breakin, installed the inner springs, checked the lash this spring and nothing had changed. I'll check it again next spring. You soon get used to the sound of solids, it's like music to my ears now. Dave

The solid I'm considering is the Comp XS274S. Plugging it into the CamQuest program, it showed about 10 more HP @ 500 RPM less, and nearly 40 lb/ft of torque advantage over the XE285HL. Its description says it also requires less compression and converter than the 285, which leads me to believe it would be more streetable. Lets see..... more power, lower in the band, and better streetablility???? Is there anything here that doesn't sound good?

Run the solid and don't buy into any argument that a hydrualic will work better.Listen to the other posters who have run both and you will soon see why people like them.It is a no brainer.

So, the specs on the XS274S are: 238*&.502 in. / 242*& .510 ex. on a 110*cl. I like the power potential I see, but are there any others I should consider that may offer a little more lift.

I know I shouldn't get hung up in wanting a "big" cam. I don't want to fall into the trap of overcamming. I've come to consider the Mopar grinds outdated compared to other brands that have continually updated their technology.... should I consider one of the Mopar solids?

Just my . I'm a big fan of solid lifters,but hyd cam still have a place. The problem that I see with hyd cams is whether the hyd lifter can accuratly do what the cam tells it to. With the mild old school hyd cams it generally is easy to get a good match,as cam companies realized the public would buy the faster rate must make more hp theory they designed them,the hyd lifter often causes this to end in dissapointment. There are plenty of hyd cam lobes that don't require anything special to run well at 7000rpm and some that are a pain to reach 6000rpm with lots of "special" parts. Solids eliminate the hyd uncertainty. Hope it makes sense?

I ran a .528 cam in my 318. The car ran mid 13's, I put in a .488/.510 hyd. and it ran high 12's. I won't go back to a solid. Yes the new cam was probably a better fit but I was sick of doing the valve lash.

Setting the valve lash is not a very frequent activity ,but some seem to struggle with it.

This is a weekend driver that goes around 2500 miles & sees the strip a few times a year. I think I would adjust the lash once a year in the winter. If I had to do it once more a year.... no big. I enjoy garage time.

I took a look at Mopars solid cam selection. I don't think there's much updated technology there.

I get the idea that Don was saying it's apples to oranges with HYD to SOLID... I've struggled with this too... Since it's a theoretical, on EXACTLY when things happen on a cam anyway. Toooooo many variables. People took the .528 vs .509 as literal when it is only an example... .528 MP vs .509 MP is 112 LSA vs 108 LSA...Now that's apples to walnuts ..Not to put any words in Knowsnothings's mouth but what he was getting at is all things being EQUAL, LSA, Installed ICL, ect...

FWIW there are some tremendous HYD cams on the market and should be not dismissed so easily by those who have not run one yet.

Cost is a factor as I understand on this build You're going to need adjust-ability somewhere...If you go solid, were is that ADJ going to be? quality rockers are not cheap, I have $500 in my Comp mags on my 383...and cheap rockers are not quality, ask those that have run CATS ... Adj push rods are a special order, again not cheap soooo....

Guys! I see comments here on cams wearing out because of the lack of Sulphur in the oil.
This is so true & its an easy fix.
Use a single viscosity oil for Four-Stroke Diesel engines.
These still have the much higher Sulphur content to lubricate.
Have a look at what Dave Hughes @ Hughes Engines in his Tech: column has to say about it.
He is spot-on!
