A little bit of engine **** for your Monday afternoon courtesy of our in house Engine builder/Machine shop Mike from MCP Competition Engines.

Joe Dedona's 427 RHS is back together and just waiting to get back out to the track!

 

Joe dam man one hel* of a set up by the looks of it.

 

It looks great, but the intake is on backwards.

 

and missing coils... looks like you have a opti on there though.. is that a new LT1 i hear so much about?

 

Adjustable cam timing its got to be LT1.

 

awesomeness.

 

Is that a direct bolt in? Do you take trade ins?


I can't wait to see y'all back out a the track.

 

Can we get some more info on the build?
Cubic inches, compression ratio, power adder, what class is it racing in, goals, etc?

Also, if the Clown puts this in his car will it go 9's?

 

Wicked sick!

Are those -10 AN crank case evac lines?

Thanks,matt

 

I'm always the last to see the good full res pictures

 

Matt -10 or -12 dry sump hook up lines is all I am looking at in the pic,s. Robert

 

The valve covers are wrong position L/R in that picture. The ports should face rear of engine.

On the original build those port/lines were going to a puke tank in the trunk with a 1-way check valve out-from-engine only this way the oil pump scavenge would build vacuum.

Motor never did build sufficient vacuum so I am installing a vacuum pump to assist the oil pump.

What those picture don't show you is the condition of the pistons I took out of that motor.

The brain surgeons that were in charge of the motor ordered the wrong pistons for that combo.

How do I know? First off there was almost no clearance between the Aluminium rod pin end and the piston pin area. Also top of upper rod end would hit the underside of the piston top. Original engine guru repaired this by taking a grinder and removing material all around the areas that hit. There was other stuff like cam bearings improperly installed, etc. You get the point....

I called JE to reorder the same custom pistons (spc order number stamped into piston bottom) and was told those pistons were for a steel rod not an aluminum rod (which I have) and although there is no "official" HP rating they put on a piston they wouldn't go over 1500 HP with that forging. JE built me the correct forging with a larger pin, and beefier pin boss area.


The good news is that I was lucky to tear it down when I did as 6 of the pistons had cracks from pin boss are moving towards ring lands.

Who know, maybe 1 more pass and instead of a rebuild I would of had a pile of scrap metal.

Anyhow I hope to get it installed back in the car this week and on Tune Time's dyno for break in.

 

Nice build Joe, love the RHS block. You do have a wild azz build. Robert

 

Thanks, the combo managed a mid 7 sec pass.

Looks like I will be running Real Street for 2014 while I get my new Drag Radial motor done.

RS a step down in blower to a F1C but it is a fun class. I think this current combo I rebuilt will hold up real well in RS.

As for Drag Radial, you really need a billet block to take the high HP levels required to be competitive in that class.

Looks like myself and 3 other DR class racers are doing a GB on a solid billet LS block.

I'd like to clarify my previous post, when I refer to the "engine guru, etc" it is direct only toward the actual person/shop that machined and assembled the motor. I hope that no people, pets or shall children were offended by my description.

I hope that small children don't get too near that intake and get sucked into the blower!!

cubic $$$

love to know how much that intake and valve covers cost (source please!!!)

looking for a fab intake form my Twin Turbo car if I can squeeze it into the budget. if not, just the valve covers!!

what a nice setup. curious about the front mount distributor too and why that was used. very common on race cars but what's the advantage over the coils???

running an MSD programmable box?

thanks for any details, awesome build!!

 

The intake is from Marcella. IIRC I paid 3500 and waited months for it.

If you want one that functions just the same but not a "shiny" there are other fabricators that will charge you less.

The valve covers are billet aluminum, designed and machined by Jesel. They are a work-of-art.

I do not have a price as they are part of a support package for my car but I can get you a price if need be.

The distributor vs traditional COP...... You will get proponents of either combo. I suggest you do your own research and this is a good thread to read http://www.yellowbullet.com/forum/sh...d.php?t=526145

IMHO there is a limitation to the high HP builds that approach 9k with reluctor/COP setups.

I like to have total control over timing through MSD so I run a crank trigger, MSD 8 Plus Ignition box and a MSD Power Grid Control.

 

It could have a stock LS6 in it.....Still my favorite Z06 of all time.

 

Agreed. Its bad ***!!

joe your big wheel stand was my phones screen saver for a long time!!
