Would that be Levee Cutta? :o

I'm just surprised about the inch of lift in non-roller Nascar motors.

Re: Ya gotta be kidding...
 

Yeah, that is a problem for the D3 heads in that FoMoCo only sold the heads in an unfinished form and left it to the engine builder to complete the ports and combustion chamber. The NASCAR guys built a huge variety of heads designed for particular tracks. Short track heads were completely different than fast unrestricted track heads and restrictor plate heads were different than all the others. So going to Yates or whoever and buying a set of D3 heads won't get you to where you need to be for a drag race engine. It would be really expensive to develop an optimal D3 head for drag racing since it is really new territory. A NASCAR head developed for a track like Martinsville would probably be a good starting point.

I need a junk, wore out, blown up, damaged D3 head (1) so I can do some R&D on the ports and combustion chamber.

Thanks in advance

RJ, check your PM's.

I never mentioned anything about using an E-Bay engine in S/SS; you did. And yes I am very familiar with what is involved in putting together a winning Stock/Super Stock engine program. I cut my teeth working for Captain Cobra Jet in the 80's as well as working along side his son Chris. I also have friends who currently race in Stock, and Super Stock. So again yes, I know what's involved in putting together a competitive program.

And yes I agree just about everything is a spec piece from the block, bore size, stroke, rod length journal, and weight, piston dome, valve size, rocker ratio, port volumes, and camshaft lift. That's the beauty of this deal, everything for the most part is available off the shelf and readily available. No more chasing down old head castings. I never said used Ebay heads would work in this application. This was an assumption on your part. I was referring to some off the shops who still have bare castings laying around and available, as well as Jesel rocker bars, arms, and shafts . All Ford Racing D3 castings are cast with the same part number M-6049-D3. Everyone knows In Stock Eliminator the intake manifold will be what ever piece(s) and part numbers Jesse submits. In SS it's what ever you choose to use.

We do have Chris and Jesse to thank for bringing the 352" Sbf and the 428" Sbf to stock and super stock eliminators. And now they have given Ford Racers another bad *** killer bullet. I stand by my above post that this will be a good thing for Ford Racing in the sportsman classes. If I wasn't already chest deep in another class car build, I would be all over this.

Re: Ya gotta be kidding...
 

They're not, they are at around .900" lift, rocker ratios are over 2.4 in some cases.

A Nascar cam looks like a Mickey Mantle bat that someone worked over with a wood lathe. Big ole bubba. I think they still use mushrooms so no failure on the roller.

Re: Ya gotta be kidding...
 

Any more info on this engine? specifically, port volumes, approved rods and crank?

I have some info but not enough.

Thanks

Re: Ya gotta be kidding...
 

D3 engine in stock is the biggest joke coming out of Ford and NHRA. The rules originally intended for stock do not apply anymore.

I feel bad for all the guys that have worked for years on there combos to have to deal with the Made up combos coming from OEM.
