Go back and read what I said before you get all bent out of shape . You need to understand what I said. 

Ditto-All I am stating is there is more than one way to skin a cat. Every here seems to think there is only one way to build a motor, but if you lack funds, there still is a way to make power and have it last more than one run.

You inferred I was an idiot by throwing in the muffler bearings comment.

No, never inferred to you as an idiot, just referred to you as common sence chalenged, but if it makes you feel better, I can refer to you as an Idiot-

"...bring cash-cuase you will be seeing the tail lights of my 13:1, 400HP, 4.11 geared, big cam, cast crank, 383, lol..."

I just noticed your statement above.  Good golly...  a 13cr 383 humpin' only 400hp?  Something is keeping your combo down.  There are 13cr 283s making 400hp.  Peace

I was using CSIROC's quote, being funny, but you didn't get the joke. lol 

CSIROC wrote- "Contradict yourself more. Please. Who builds a 400HP cast crank 383, with 13:1 pistons???" And wrote- "You have fun with your 13:1, 400HP, 4.11 geared, big cam, cast crank, 383. I'll be driving by on the highway with my 10:1 compression, 400HP"

And I informed him that is not what I posted, but I posted-

What I said was: 

I also put a 300 shot on a stock Mustang GT with cast crank and cast pistons. 

Duck and cover!!

"...I have made over 850hp on a chevy cast cank (600 motor + 250 shot) before import cranks, its all in the machining of the crank if it will live, I have a stroker 365 chevy with a cast crank that spins 8500."

Sure.  And Santa is real.

Wow, JCharlieM, of all people not to believe me, I thought you were old school. Anyway here are some people making the same kind of HP  or more HP with cast cranks-

I am old school.  That's one reason why I question your statement of a small Chevy cast iron crank handling +800hp while on juice.

Having built numerous sbc motors(as I'm sure you have too, Gibs), he's full of B.S..
You won't run 13:1 comp. on pump gas,HRM PGD'S, Engine Masters, some went with 13:1 while others went with 12:1 on pump gas- 

"The compression used by most contestants was 12.5:1. This seems to be the power sweet spot. 13:1 is a little high and 12:1 is a little low. 12.5 is where I suspect we will see most engines in the future."

CHEVY Mania!

In the late 80's early 90's mag's wrote alot about Joe Sherman built  383 SBC motors  with cast cranks, many used his comb's and added as much as 300 shot of Nitrous to these combo's. Good forged Cranks costed $2500, so machining a 400 crank for @ $150 to 350 mains was really the only choice. His motors made excess of 700 HP, we were no Joe Shermans, our motors averaged 600 HP, but add 150 to 300 shot of nitrous and we were right there in power levels, his cars went low 10's, high nines, ours went high 10's on the motor and low 10's and in the 9's on nitrous with his combo. We paid $250 plus freight for one of his cams, and it was worth it, we ran those same spec's for many motors for many years, and if your wondering what those spec's are, it cost you $250. 

 I also put a 300 shot on a stock Mustang GT with cast crank and cast pistons.

I did not say there wasn't, all I said was you should get a forged crank not that you have too. You implied that I was suggesting items to fatten my wallet which I was not . I was merely suggesting that a Forged crank for someone money challenged might in the long run be more economical if he SHOULD happen to blow the thing up. Suggesting which parts a customer should buy has as much to do with the technical acumen of the buyer as it does anything else and I think in the case of a highschooler a pennys worth of prevention is worth a pound of cure.  Also what year was that Mustang because if I am not mistaken 5.0 GT engines with the exception of the 92-3 were forged piston engines, not cast as you stated. 92 and 93 were cast hypereutectic so just curious as to what year you built there.

I disagree, a cast crank will handle anything this kid will throw at it due to the fact he is money challenged, not just my opinion either -  CHEVY Mania!

"How much power will the stock 400 crank handle?
I have used a prepped 400 crank to 700+HP I have used basically stock cranks to over 550 HP so a stock nodular iron crank is fine for most buildups. The crank is strong because of the beefier construction of the crank."

I'm not the only one to do this, many others have, and mags have writen about it-

We quickly hit the engine with a one-two punch of 100hp and then 200hp nitrous hits that the engine handled without a whimper. With the 200hp kit, our mighty Mouse was steamin' at 521 hp with 587 lb-ft of torque! Next, we hit it with 300hp and saw the power shoot up to 599 hp and 655 lb-ft of torque. When we re-baselined the normally aspirated combo, our little hero small-block stepped up with 325 hp, an increase of 15 hp over the previous baseline. We attributed this to better ring seal after the nitrous knocked the carbon off the rings! Now we were ready for the big squeeze!

I can't even begin to follow all the B.S.! See ya

Well If you would read My posts I have a scrap pile of junk cast Scat cranks that say NO they will not handle whatever you throw at them . Now you can either believe that or what you choose to think because of your experience . Hey your decision . In your case it held up greaT FOR YOU !I on the other hand have a pile of warranty cranks that have been split in two because someone over did it . With too much nitrous 200 + shots , supercharging or in some cases heavy towing loads. But you seem to to be the genius here you have him buy that cast crank. Oh and your Mustang had Forged pistons , it was 86  right ? They were forged. Good luck to ya . I know I do not want to follow your burnout because the clean up one of these days is going to be time consuming.
