She looks nice, we'll see what kind of power it makes. With the new Jesel valvetrain the cam lift is around 0.800. Other changes are the belt drive, belt driven distributor, crank trigger, 440-3X intake, and the reverse flow water pump.

EDIT - the motor made 674 ft-lbs at 6100 rpm and 805 hp at 6400 rpm.

Cool stuff as always Andy.

Is that an oberg oil filter?

Whats the benefit of the belt driven distributor?

Doc.

The oil filter comes from Racor. I think that Racor bought out Oberg but I don't know for sure.

The belt driven distributor is just an easy way to solve a few problems. It gets the distributor out of the way of the valve cover, it makes the plug wire routing a little easier to deal with, it makes it easier to prime the oil pump and the big cap reduces cross fire. On the down side, it gets in the way of the thermostat housing.

Here is a side view with the valve cover pulled off.

Sure looks like an olberg filter I used to have, only it wasnt gold.

I assume the dist. is run off the cam?

Nice lookin toys Andy. I see they canted the rockers

The rocker arm setup is a custom deal that I did with Jesel. These are CNC ported EZ heads that do not need the 440-1 type offset. But Jesel only sells the 440-1 offset rocker arms for Indy heads so I had to come up with something different.

We used the standard offset exhaust rocker arms on both the intake and the exhaust and had some custom spacers made up to center the intakes on the valves. I provided Jesel with the dimensions so now they can make more kits like this if people want to order it. I also provided the info to Russ at Indy but he didn't seem to impressed. Maybe I just caught him in a grumpy mood or something.

Here is a closer picture of the rocker arm setup.

Imagine That !!!!

Is this engine for competition or something? ...I have not been paying attention

yea heaven forbid you should improve something...once again you've lost your mind Andy. i went through some agg with ARP studs for a megablock. when i called ARP they said that the standard hemi kit would work for this application but when the guy gave me the lengths they weren't the lengths i believed would work when i measured things up. ordered the hemi kit and they were too short ended up sending them back and ordering loose studs in the lengths i measured which fit correct. told ARP they should look into packaging these lengths for a megablock kit. don't know if they ever did but i don't think so

Andy, are you going to rerun it with the Indy crossram also?
Doug

Looks great, Andy. Did you change cams or are you still running the solid flat tappet? Looking forward to hearing the results. BTW, that Indy 3X sure looks big .

Andy, how did you manage to space the offset rockers so they'd work? It's not quite apparent from the pics, and I'm unfamiliar with the Jesel setup. Did doing this require opening up the pushrod holes towards the inside?

Andy, your new wires for the front-mount are being built next week, and you will have them by next week for real-world dyno tests. Thanks for waiting for the 8.5 mm's. Awesome work , bud. You have a fun job !!!!

The cam is a Comp solid roller. 275/282 at 0.050 so it isn't much bigger than the flat tappet that was in there but the lift is a lot more. Lift is now .830 intake and .782 exhaust before lash.

Those are all exhaust rocker arms, we just paired up 8 LH and 8 RH to get the correct layout. By using exhaust rockers on the intake the pushrods lined up perfectly with the standard lifters and the existing pushrod holes in the head. I did have to clearance the heads a little for the pushrods since I'm using big 7/16 pushrods but the holes in the head did not have to move. If I had used the standard Jesel intake rocker arms I would have had to move the pushrod holes in the head.

It did take me a while to figure out how far to mill the head to accept the Jesel stand. Jesel didn't have the dimensions for these heads on file but after I worked with them a bit they came up with some dimensions and wrote some instructions that you can now download off of their website.

Here is a picture that shows the difference between using exhaust rocker arms on the intake and using the 440-1 offset intake rocker arms.

The cylinder on the left has the 440-1 intake rocker arm which moves the pushrod over too much for the EZ head. The cylinder on the right has two exhaust rocker arms and the pushrod lines up in the proper location.

very good info, thanks. what installed height and diameter on the springs did you end up with?

The roller tip is parallel to the rocker arm main shaft. The rocker arms are at an angle but the shafts are parallel to each other and to the camshaft.

The springs are 1.645 OD and set up at 2.00 installed height. I tried a bunch of different locks and retainers before I found a combination that cleared the rocker arms and gave the proper installed height.
