I was told to come her.......Had some questions about the engine wanted to know how much power it will hold I was looking to punch it out to a 408 and run a 76mm turbo .....
Of course Dart only claims their blocks will only handle 600 horsepower. That way, when someone scatters a 1000hp motor they can always claim it was only capable of handling 600.lol, these old antique cleveland blocks seem to be holding more horse power every year that goes by
...just some common sence for those thinking of trying to put alot of hp through a 40+yr old antique factory block...
the superior/thicker aftermarket Dart shp block is rated safe to 600HP by Dart them selfs, the block itself can handle more hp but the reason Dart them selfs only rate the shp block good for 600hp is because of its 2 bolt front/rear iron caps, with a 4 bolt cap upgrade on front/rear the block is good for 700-750hp and if you are looking to make more hp than this it is recomended by block manufacturers themselfs to upgrade to billet STEEL main caps which can hold much much more hp.

He said pro stock racing, which explains why the block failed.Boss, what are the details on the build? Compression, fuel type, timing, cam specs, rpm limit, etc...
Rod and stroke combination? What type of racing?
the blocks not mine, pic from YB, the guy was running a boosted roots app with factory iron caps, the point is some have had problems with the stronger old nascar c blocks so a factory production block is not going to be any better for high hp apps.
if a guy really wants to stay with a c block i would suggest to go with the new Arrow c block, it comes with billet steel caps, much better for high hp builds.
I have thought about that but I would be too worryed about the Dart ie block Cracking/Busting in half as guys have been complaining about Dart ie blocks Cracking/Busting/Splitting in half since 2006 with NO answers from any of the online/internet bigot/racist/islamist YB dart dealers/peddlers that sell Dart blocks out of there barns/sheds online as to why cracks keep happening on ALL these (brittle imo) Dart blocks...

("I also have at least 12 racers that have broke their dart blocks as I have and the problem is the block. Burning a plug and blowers blowing up I'm sure don't help but from all that has come forward to say their blocks have broke in the same spot leads me to believe the block is failing.")...

Its been running for 2 years in the 9s, and 8s now. Countless passes. There's plenty of proof bud.so how many perfect tune 8 sec runs has that 1000hp stock w block made?, guess those of us with aftermarket blocks, cranks, rods and pistons should throw our shat away and go buy a bunch of $100 junkyard c&w stock cast piston short blocks as they must be just as good :rofl:.

You don't understand the difference between a low compression, low rpm, non stroked motor vs. a higher compression, higher rpm stroked motor.so how many perfect tune 8 sec runs has that 1000hp stock w block made?, guess those of us with aftermarket blocks, cranks, rods and pistons should throw our shat away and go buy a bunch of $100 junkyard c&w stock cast piston short blocks as they must be just as good :rofl:.
