Stoker kit / engine reliability?

I have a 90 Fox Body Mustang turn key bracket race car with a 521 CI stroked 460.  I had the car sold until I told the potential buyer that the engine was not in fact a 460 but a 521 CI stroker.  He and his "engine guy" he brought along with him balked at the sale because they stated that even though the engine was built for NOS that the engine wouldn't last long under the rigors of Drag racing due to it being a 521 CI stroker instead of a 460 CI.  Is there any truth to these guys story?

Engine rotating assembly is a Scat 1-47606 all forged internals consisting of the following;
Scat forged 4340 Crankshaft
Forged aluminum +36 cc pistons
Forge 4340 H beam forged rods
estimated 11.5:1 compression

John Kaase massaged SCJ aluminum cylinder heads
Running 114 race fuel  

With all my experiences with engines and SBF strokers I have never heard of such a thing.   Any input would definitely be appreciated.

Sounds like a tire kicker to me with not knowing what he is talking about  sounds like a hell of a motor set up

What rpm does it turn?

What are the clearances? What kind of oil system?

Regardless the stroker will hold up fine its the love and care taken to put it together that will tell the tell.

His "engine guy" is either completely unfamiliar with BBF's or he's a fool...or both.

An all forged bottom in a 521" bracket car is about as reliable as it gets. I've long since lost count of the number of high to mid 5 second passes on the old 514. 4.3" crank, standard 4.36" bore...has torn up lots of driveline parts, but never an engine part of any kind.

Blow those clowns off and sell it to a Ford guy, or keep it and flog it.

BTW, how much are you asking for it?

Selling entire race ready car with that setup with an additional parts car for $10,500

Additional specs:  Built C6 with 3400 stall, reverse manual valve body, Built 8.8 with 4.56 (from what the previous owner stated) rear gears with full spool and 31 spline Moser axles. 2 sets of Weld wheels, one set with street tires and one set with brand new 28x10.5x15 MT slicks and almost new skinnies.

Pics available.
