Roush VS. Ford Racing Engines

CobraEd:
Roush AL motors are Cast internals. And not produced anymore. Jegs must have bought a couple.
Roush R Motors are all Forged.

The only small block that Ford produces with all Forged bottom end is
1. The SHORT BLOCK you listed above
2. M-6007-C392FT/RT 475 HP Assembly.

Rest of Ford Racing motors are
392 430 Hp is only forged pistons.
351 385 Hp is only forged pistons.

All 302 based motors are cast everything.

385 Series motors vary on which one, but none have a forged crank.

Based on this post being in 429/460 talk.
I figured Gburg was looking for a 429/460 based motor?????
And if he was going to buy a short block and build it himself he probably wouldn't be asking about crate engines!?

ROUSH 427R is all forged and a better value than people think given the total package.

Cobra Ed -
Take a pill and chill. No need to shout. I can hear you. Take a look here:

and here:

The 427R and the M-6007-D392 engines are the ones I have owned and I was speaking of. The 427R is forged everything. The M-6007 is a cast crank.

Besides the forged/cast non-debate, the two motors are night and day difference. Both in cost and performance. I've put a lot of miles on both of these motors. I'm not making it up. In my personal, first hand experience, you get what you pay for in both of these motors. If you don't agree, fine.
Have a nice day.

I would strongly recommend visiting the 385 series engine forum at www.460ford.com and asking there if there is a seasoned and knowledgeable builder in your area, and work locally.

Why?

Engine shipping is expensive; and considering that if you have ANY problem with ANYTHING, you will need the aid of a local builder anyway...any mail-order company can't help you until you return the engine; which means removal from the vehicle. You are much better served to get a local guy to craft you something locally; and take responsibility for it locally.

Aside from that, there are guys out there that can far surpass the bang/buck value you're looking at with the other builders you're considering.

Hopefully there is a godo builder right in your area; that would be ideal.

Cashburn is likely more knowledgeable than I am about this but I believe from my talks with Roush that if you have an issue with a Roush engine, any authorized Roush repair facility can do the work under warranty. I called Roush regarding routine maintenance to make sure that I didn't void my warranty by doing my own oil changes and so forth and at that time I asked if any warranty issues come up how I would go about getting it taking care of and they told me to go to either McMichaels Motorsports, my local SPF dealer or Chuck Keene's who does the installs for McMichaels.

Gburg,

You can probably get a much better deal with a local builder than either of these motors. The BIG question is, where ARE you? Knowing that, we can possibly help you find someone good near you.

I am currently working with an engine builder on my new engine. Since I have been buying all the parts on eBay, it's taken three months to get the block together. The total price per horsepower will be OUTSTANDING, though!

What is the difference? I am using "crate motor" in the generic sense.

Hi Don -
Yes. The same thing - I can't spell.

I'm not sure what the advantage of the "hyper" pistons is over forged - simply cheaper I think. One disadvantage in "hyper" pistons over forged is: if the engine runs too lean the combustion chamber temperature goes way up. When the temperature skyrockets the "hyper" pistons essentially turn to glass and shatter. If your twisting aboout 6000 rpm at the time the residual damage can be catastrophic.

This would not happen with a forged piston.
