I have the rotating assembly ordered and machining is happening. For a hot street 400 in my 65 should I be considering a solid?

To get the most performance out of it, definately. Depending on how much cam you go with, a solid setup requires maintenance of course as well. Not a big deal tho really. What's the rest of your setup and what kind of performance(hp/tq or 1/4) are you looking for?

A hydrualic roller setup can get close to as much power as a similar solid setup and will require no maintenance but costs at least twice as much.

I am running a Comp Cams hydraulic roller in my .060 over 400 sb. Specs are .510 .520 236 244@.050. I am using the Edelbrock Performer Rpm heads and the combo has been trouble free for 20.000 miles. I am also using Harland Sharp roller rockers. Motor is balanced, deck squared, decked etc etc...Motor is very torquey and a ball to drive with a Muncie m-21 and 3.90 posi gear!

Unless you are pounding the crap out of your motor, solids are NOT high maintainance.
If you have screw in studs, you should have no problems. Every time I have checked my valve lash, it has required NO adjustment. This is with a 548 lift Isky solid, in a 355 SB.
The last motor I had with solids, was also a 355, and it had pressed in studs. Again, every time I checked the lash, it required no adjustment...and I pounded on that one pretty good. :D

im sold on my hydroroller in my 383 (see times below) although i dont think my cam is the perfect grind i think getting the "right" cam, convert for a street car is probably more of an issue than solid or hydro. just my .02 Dave

Yup, solids are the "working man's" solution to free HP.

In all candor, if you zing this puppy up to 7000 rpms frequently, you will have to touch the valves at times. Otherwise it should be a once or twice a year deal, except fort the initial run in where you might get sick of it after 4 or 5 settings! ( I attribute that to the relative intensity of the cam I run, a gentler grind wouldn't be so 'jumpy').

For my next low rpm stump puller, I'll likely use a HR, again, for the HP over a hyd and hassle-free inital start up.

Thanks guys. I think UDHarold is a little busy right now so I am going to post later on a cam recommendation
