Yep, that is what I'm thinking also. We changed plugs and did a quick look at everything but nothing obvious showed up. I'll just go back to basics and run a compression check, set the lash, etc. to see if we find anything. The motor sounds great and makes more than 800 hp on each pull, but it just doesn't respond to any changes.

Andy thanks for your honest reply.
Probably would'nt be cost per HP effective eh?
Thanks, Don

We never did find anything wrong with the engine. The oil filter is clean, lash is fine, plugs look good, compression is identical in all 8 holes, etc.

We calibrated the dyno and double checked everything we could think of. Could be that we're just at the limit of this cam and head package which is why changing things like spacers and carbs and such doesn't make much of a difference. We made about 30 dyno pulls over a period of several days and all the good runs ended up being about 820 hp.

All was not lost though, we did get to test a ton of parts and we tried a bunch of new things. Most of the new stuff didn't work out, but that is still useful information.

Here was one of the new ideas that we tried. We've had problems in the past trying to figure out if the water pump was working properly on the dyno. It isn't uncommon to hear about people smoking an engine on the dyno because the electic pump failed but they didn't know until too late. I think it has killed a couple of engines at the EngineMasters.

So we made up a sight window for the water line distribution block. Now we can look thru the cell window and see if the water is circulating.

The clear valley cover also worked out pretty well. You can't really see too much when the engine is running, but it gives you a general idea of what is going on. The oil spray pattern on the window was interesting. It made me think about some oil control stuff.

Great idea, I have a Meizere water pump , always wanted to know how it pumped, make it a little smaller and I think a lot of people would purchase to install on there cars. Ill take one with 16 line.

I could make these as a product but there just aren't very many guys running dual hose setups. I could make an in-line window of some sort but that would be a different product. A sight glass on the side of the water pump itself seems like a good idea.

One thing that I did figure out after the engine was back home was that my new Moroso vacuum regulator was stuck open. That was most likely the main reason that I couldn't build much pan vacuum. I had assumed that it worked okay since it was brand new, but that was a bad assumption. I ended up building a little fixture so I could test it and that showed me the problem. So that part went into the trash and I ordered a new regulator from Peterson.

Moroso used to make really good stuff but lately the parts I've gotten from them have been pretty poor. Maybe they're under new management or something.

about 820 hp or it made 820 , can you post sheets so we can see power band ect.

I started to pull the engine down to make a few changes. These Superformance intake gaskets work like a champ. We did a bunch of intake swaps on the dyno and the gaskets still look like new.


Andy who makes this valley inspection plate?Is it one of yours?If so who sells it?......Thax

The valley plates that I make usually have a SST center plate. I just replaced the SST plate with one made from polycarb. I don't sell the clear covers at the moment but I might in the future.

I guess i should have been a little clearer The valley cover it self who sells it?and can i see a better pic of it?

Valley plate with a solid cover is a standard product. AR182 and you can buy it from any of the usual dealers. Mancini Racing, Hughes Engines, Mazzolini, etc.

If the reversion plate deals work , I'd think they would work best on an engine like mine (small cid, big heads, big flat tappet)
Your dyno#s seem in line with the 500+ motors from around here. I'm not sure why some can only make 720 with the same type of parts..... I guess the sub sea level on track testing gives one the impression that less hp can net the same ets..meaning other people are on happy dynos.
Would you ever try some 440 -1s on there?

I think I'll just keep beating on the EZ heads to see if I can hit the 900 hp mark. Just seems like an interesting challenge.

The intake manifold went to Wilson for porting and Charlie is building a new dry sump pan that will be deeper and wider. Dwayne has the engine specs so we'll see what he suggests for a cam. I should have the engine back on the dyno around the end of the year. I might put some new pistons in it to get the compression up. Right now it is only 12.5 which is really too low to make good power. I probably need to bump it up to 15:1 so the engine will work better.

I'd love to see how my Chapman 285's would do on that block against the EZ-1's. The chaps are well known for the intake flow but with a 2" tube they flowed close to 300 @ .700 on the exhaust with the smallish but apparently very efficient port. It'd be an interesting comparison for sure, I suspect you're at the saturation point of the exhaust where it's simply slowing down the pumping rate (ability to keep accelerating) at high RPM which in turn limits how much draw you can N/A draw on the intake almost regardless of flow potential.

They'll say the exhaust just isn't as important and it's not at moderate piston speeds and RPM's but sooner or later you slow the pump down when you can't get the air out quickly enough, more valve timing can help to a point but eventually. with a 500 inch motor it's like using a piston to push fluid out of a filled 1 litre bottle...if one has a standard opening and the other has a Mickey's wide mouth, at some point, sooner or later Mickey's gonna win.
