We got the 514 fired up today. This is one of those projects where the parts have been sitting around for a while so I finally took them all to the engine shop and asked them to finish off the motor. I just wasn't ever getting around to putting it together myself.

Mopar block with 4.440 bore and 4.150 stroke. Indy EZ heads. Cam is a small solid roller with 266/272 duration. Flat top pistons with compression around 12.4 to 1.

The motor really runs well, actually too well. We limited out the dyno on about the 5th run so we were done for the day. Looks like we tweaked the load cell in the dyno by making more torque than it was designed to handle.

Not sure what kind of power this sucker is making, best guess is something around 850.

Nice combo!! Mike Jones cam?

Get a bigger dyno . Mine is a L&S dual-stator toroid-13" 2000hp capacity.Dave

OK, you definitely have our interest! Can you give us a full run down of the head flow, valve size, lift of cam, type of springs, etc? 650 is some very good territory. How close to a proper tune do you think you got?

Always love reading stuff like this!! Thanks,Andy!!

More info!!

Sounds like an awesome engine Andy!

ok andy,you have our attention. i'm currently building a 499 and would like to see you ez head combo.

It's always good to hear that your motor made so much power it broke the dyno Better than the other way around.

Yes, these are the EZ heads off of my old 505 motor. I broke the block on that motor so I decided to only use these EZ heads on an aftermarket block. I put ported Edelbrock heads on my 505 and moved the EZ heads to this 514.

Heads were ported by Jeff at Modern a few years back. They have Jesel rocker arms, 1.85 I and 1.70 E. The heads flow about 360 cfm on the intake on Dwayne's bench. Intake is a OOTB Indy 440-3. Carb is box stock Ultra Dominator. This is a three circuit carb and it was dead nuts on right out of the box. The three circuit Dominators that I've run in the past were always dead rich but this one is right on and it made some power. Soon as we started to make pulls we could tell by the sound that the engine was right in the groove.

Was the 505, the stock block dyno mule that made upwards of 800?

What happened to the block?

I'm running a dry sump on this motor. I really like the dry sump setup. It is so much easier to dial in a dry sump and the engine oiling is a lot better. Hate to go back to a wet sump design after working with a dry sump.

Pardon the typo in my previous reply. 850 hp is definitely a step above. Your combo is using less cam, less compression, less cubes than most any 850 hp combo on the board, if I have followed all the right posts. Our (or at least my) interest is in how the philosophy of this engine build can be duplicated and used to increase hp on bigger motors as well. Your use of the EZ heads with less exhuast flow than a 440-1 is interesting. It points to the possiblity I should go back to a cam with less duration on the exhaust. Same with the rocker ratio. There must be improvements in valve control to be had.
Anything you care to share will be greatly appreciated.

Well it has taken a few years to get here. These same basic parts were making 650 hp a few years back but we made a number of changes and the power steadily increased. The move to the Jesel valve train really picked things up. The motor showed a lot of improvement with the bigger bore size in the World block. I think the gas ported pistons also added some power. The dry sump made a difference. The belt drive made a difference and so did the belt drive distributor and the crank trigger.

None of this should be a big surprise. Higher end drag race motors have been using these parts for a long time.

As always.. You do it again.. Nice write up Mr. F. I don't think I'll need that much power with my 516 but sure wouldn't mind aslong as it could live on the street. Thanks.

Cool beans

I know it's been a long time in the making, block has been around for awhile etc...congrats!

So what did it actually make?..or dont you know.
