Help Me build a Ford Pro Stock Motor

[ScaleDale]

Hi, all. I’m in the planning stages for a series if builds of contemporary (2010) Pro Stockers, starting with a Mustang similar to the one driven by Larry Morgan in the reference pics and seek your input on dressing up the motor. It’s a 500 cid Ford push-rod hemi (not HEMI) that isn’t available from any kit or resin molder that I know of. It’s based off the BOSS 429 found in the Revelle ’70 Mustang Mach I with a dry sump oil system like in the “shoe box” Chevy and Ford Sportsman kits that are out. The intake and carbs are easy to do with stuff I have. I could use the 429 block and mod some valve covers or get generic resin ones, what do you suggest? Note how the inside spark plug wires are paired while the headers are evenly spaced.

Gibson makes a 429 PS motor

Your picture almost looks like a newer Coyote block

The engine photos have time stamps from December 11 and 12 of 2009, I think the Coyote was still in development at that point. No matter, though, Coyote engines are all multi valve overhead cammers which aren't allowed in NHRA Pro Stock. That has to be a 90 degree two valve pushrod motor.

I have that Gibson in a 56 Tbird and it's huge!

i don't want to rain on your parade but, the ford pro stock hemi is not based on the 429 "shotgun" at all. it is a specific, special purpose built engine. you will note the similarity in head design to the mopar pro stock hemi. possibly the only thing it shares in common with the "shotgun" is the 4.900" bore space. then again, ALL nhra pro stock motors whether ford, gm or mopar all now have 4.900" bore spacing.

there are a couple of good articles out there. i quickly found this:

You aren't raining on my parade, only backing up my suspicion.. There is nothing remotely like this motor available from Ford Racing. Only a very few Pro Stockers run them. The only thing that connects any badges Pro Stock motor to the factory is a number stamped on a rough machined block of hardened metal that is finished by a specialized engine builder.

Thanks for the link.

if you are going to scratch a motor for your model some of the specs for the block are available by googling ford pro stock block and going to the website that sells the block. things like bore spacing, cam to crank centerline deck height etc. are available. there are also some nice 3-d images availble on the web by searching. the block and both the hemi head and the symetrical port heads can be found, althought the hemi head seems to be the preferred head of choice.

[ScaleDale]

I'm not quite that crazy to try to scratch build a 1:25 motor

I'm just looking for a reasonably well proportioned available motor that I can add some Bondo to the valve covers and make them look like the one in the Larry Morgan car. I'd go crazy as a builder of models if I wasn't willing to make some compromises

Dave: Thanks for the info. I did my searches on Bing and came up with less info than Google.

doesn't ross gibson sell the mopar pro stock hemi? like i said earlier, the heads are just about identical.

compare your ford head pics to this pic.

Yes. I was looking at his Blue Thunder Mopar HEMI last night. It has all the dry sump stuff that I will need and the valve covers are flat and generic. They could be sanded down and drilled to match the plug wire patterns of the Ford rather easily.

I'm going to look at the motor in the new Jukebox Ford Sportsman I have, too. I want to use the chassis to build a 49 Merc Pro Mod with a blown Gibson motor I already have. If the block is big enough, I can just scratch build the valve covers. That part is easy.

Edit: I just noticed those center plug holes in your image are paired together. I'll look that one up. Just hope the closing of ScaleDreams doesn't create a distribution problem for all the companies that worked with them, like RGE.

Here is a pic of the Ross Gibson Hemi's..... Think what you want is one of the last 3 engines...

and there you go. thanks chris.

the rge 603 looks to be the most correct but, it does look like the deck height of the motor is pretty high. the intake runners are pretty long.

it is definately something you can start with.

[ScaleDale]

Thanks, guys. The valve covers on the 603 don't have the bolt holes at the edges that the others do, so it looks like a go. Thanks for the input. I may order an extra for the Jegs Mopar if I can find an Avenger body.

If you can find a "JukeBox"56 ford ProStocker you'll find the motor your lookin for.

Yes. I just finished sorting all the engine parted out of the box and packing them up with my 2010 Mustang. It's not the "real" motor I'm looking for, but I know that's just not on the market. All I really need to do with the Jukebox motor is fill and move the spark plug wire holes. Easy.

george53,

the motor in the juke box ford is NOT the correct motor. the motor in the juke box IS based on the boss 429 motor. if you look at the spark plug spacing you will see that the heads are completely different. again the pro stock motor scale dale is trying to replicate is TOTALLY different than a boss 429. they share no family resemblance to a 385 series ford motor.

also the juke box ford is a pro mod not a pro stock.

i hope this helps.

Actually, it's a Sportsman. But I didn't want to bother to correct him. The block and intake are pretty close for my purposes and as for the spark plug spacing visible in the valve covers, the answer is...Bondo (and a pin vise).

I'll post a WIP for this after I finish my Super Street Fairlane.

BTW: Any suggestions on how to do a P/S hood scoop? The scoop is actually a hat that fits on the carbs and the hood has a slot that it slides into. The whole front end save for the scoop slides off to service the engine.

I still think that this is a sweet looking motor....
