Just to bring it to your attention, your style of writing on these boards is pretty different. It's hard to follow and read, what is up with all the colors and the breaks in the middle of paragraphs? Why don't you just bold a certain part of the statement you're responding to and respond to it a couple lines underneath it?

Gotta admit, it does make it easier to skip over and ignore though

I'll try it.

Been trying different things

Oh, were you talking, couldn't hear. You got to stand, not sit, when your talking out your ass.

Let see if I get this right, hmmmm, 400+hp will blow up if it has a cast crank.......... But no matter how many time I post other people that have made 400 to 450 383 all you "know it alls" who have not done it say I'm full of it, Hmmmmmmmmm........ Well this won't make any difference to them, but to anyone else interested in building some real power on a budget, you may like this, it comes from an author of many mag articles and many books, but he must be out of his mind, cause he is talking about 650hp 383 that also can spin to above 7500 rpm as a test engine for cams, or maybe he is just full of B.S. also, hmmmmmmm, or maybe the haters just don't know what they are talking about and refuse to admit it-

Crank,In line with the old adage that there is no substitute for cubes, our project engine used a Scat 9000 series cast steel crank (part No. 9-350-3750-6000) to stretch capacity from 350 to 383 inches. This crank is designed to internally balance with Scat’s inexpensive “I” beam 4340 alloy steel cap screw six-inch rods. If you intend to follow our build this is what you should use. The test motor, however, was to be used as a cam test engine later and would be turned up to 7,700 rpm.

the cam only has 150 miles on it and it is still in the origanal box but i will recheck the specs for the durationand let you know  

Sorry to say, but beating a subject to death is not the best way to convince someone of something. Might as well put it to sleep, everyone has their opinions, you have yours and since the majority of experienced rodders are conservative when using nitrous your not gonna convince the entire world otherwise.

Incorrect, the 83 was the firdt year with TRW supplied forged pistons in the 5.0 H.O.. Look it up.
As far as the cast crank, yes one can build a 400hp cast crank motor, no problem. But, you stated a 300 shot, above and beyond that. Won't be a high miler.
And yes, I am a builder, and corrected your statements for you, no I don't feel silly, as I've showed that building a mid hp cast crank motor is possible, but shooting it up with a huge 300 shot aint gonna happen for very long.
Do you feel silly?  

Wow how the heck did this get 70 posts?  I can see five maybe ten but 70???  Anyhoo I think most agree about the power cast crank and maybe a decent hit but 300??  Wow I just split a crank in two recently Invader I hope you bring a trailer, and something to pull it up because mine was in my driveway a mear three feet from salvation and I could even make it run with half a crank burning out both ends but running.  Yet I couldn't get it to move.  Your planning 13-1 cr with a cast crank a used cam cast pistons and a 300 shot?  How about you pass that dube this way and think about how much your planning to spend, I know it sounds like every one is against you on this but they are not they are looking out for your wallet.  I have sent a few rods through the side of the block and out of the fender and just felt lucky they didn't come at me.  I hope this works out for you but 13-1 is an awefull lot of pressure and to hit it besides.  Wow.  Any way let me know how the crank works I am thinking of trying a good used one with new lifters but for now I'm just rolling a used late model motor.

I was thinking the same thing, 70+ post. lol

I don't think anyone is really looking out for my wallet, IMO I just think they can't admit when the are wrong on a subject they know very little about from hands on experience, but only know what they have been told or they read about. IMO cast cranks are not junk, and will work fine in a 450+ motor, and not just my opinion either. Like others have said, the pistons usually go before the cast crank. Breaking the cast crank before breaking the pistons is the exception not the rule

I will let you know how it turns out, I am in the middle of building another TRW forged 13:1, short rod (400 rods w/ARP rod bolts) roller cam, 400 Chevy cast crank, alum head, tunnel rammed motor that is going in my car with a 200 shot, but will ended up closer to 250-300. It should be done before summer, maybe sooner. I'm in Cali right now so when I go to Irwindale or Paris (if they are still running dragrace events there) I will post it and you can come check it out. I know JCharlieM will show up to Irwindale (maybe I can get him to post a pic, becuase I don't have a way of doing it right now). And you can see it for your self.

Look it up, I did and post it for you, so now the ball is in your court, show me. Incase you forgot he is what I posted-

Again, don't care if I convince anyone, just stating, just cause they have not done it, doesn't make untrue.

Disagree on the experienced rodders, more like inexperienced with nitrous Rodders. What have you done with the deadly gas.

Here is an e-mail exchange between me and speedomotive about cast cranks-

Horse vs. Compression

 

This guy claims to an expert on cast 383 cranks and say's they are all junk, would you mind straight him out, as he does not believe me we I tell him that a 450 HP motor is just find with a cast crank, and he does not believe you guys have you own brand of 383 crank. Thanks, and sorry for wasting your time, just tired of someone with no experience in the matter telling people how to build their motors.

 

Here is what he posted and if you click below it should take you right to the post.

 

"I said 383 cast cranks have a nasty habit of splitting. Also do you really think Speed-o-motive has their own crankshaft factory ? I hope that you realize that they are merely buying the same Chinese castings as everyone else."

Alright Arnold back to the pen we go. Scat finishes their cranks in the US too at their own facility. If he said that about his crank at Speed-o-motive good luck to him because then they will not be our competition for long. Oh one more thing I am done with this thread. I mean it this time not even coming back to view it . Good luck with the hand grenades.

I worked for 2 seperate ford dealers, during the 80's and 90's, so believe what you want. You are kidding yourself if you think it will live long with a 300 shot. Anyway, I'm done trying to help you, you obviously won't listen to anyone. See ya later, when you're sweeping up the pieces.
