Is that sarcasm? I wasn't trying to be a dick. I was just saying.

Karl knows his **** and has done this before, with no issues.

If it can handle the stresses of a high rpm drag racing application I th ink a little street duty should be no problem. They are being used in lots of applications with great success..

 

small journals on that much stroke ain't good......................... well depends how hard you're turning the motor.

btw love gregrob's new avatar

 

Pro stock engines making double what anyone has ever made in an N/A LTx use them. With no issues.

And they crank some R's too.

I thought a few people around here would get a kick out of my new avatar

 

nahh i wasn't being sarcastic greg........didn't mean it like that i was just seriously saying im allset with that lol........and ur right prostock and circle track guys use them alot but they only need their **** to last a short period of time.......

 

Pro stock also uses a 4.600 bore x 3.760 stroke. 500ci (well 499.9). They really wind the motors out and benefit tons by using the Honda journals. I personally wouldn't do it on anything less than a max effort build (but it hasn't stopped me from looking into it for my 383...lol).

 

i have talked to people about getting a 408, the few extra cubes isnt going to make to much more torque over a 396. The only reason i could see getting one is because not to many people have them? Hell i shoulda just saved my money and stuck with a 355 and sprayed the **** out of it!

 

I have always been a "All throttle, no bottle!" man, but I think that is the way I would go. I just wouldn't cheap out on setting the n20 up very safe.

 

I always said that too, but nitrous is like crack, i tried it once and now im hooked lol. im spraying a 125 shot through my 396 last year now but now im getting some more nitrous friendly pistons and im going to spray a 250 shot. I kinda wish i woulda stayed samller cubes so i could run a shorter rod and a thicker piston to spray the **** out of it.

 

that is kind of my plan. id like to run as big a cube as i can, a slightly shorter rod, and a piston with a thicker top deck so i can spray it to hell and back and not worry about my pistons checking out on me.

 

FWIW, CarCraft did a 408 a while back. On the 9.025 deck, 4" stroke and 5.85 they used an off the shelf Probe forging for a 347 ford. Compression height was 1.175", and they planned on spraying the **** out of it. Now they did everything budget wise and used stock cast iron heads with a valve job, and a really mild cam and made over 400 crank hp. I know it doesn't sound like much, but that was based on a $3000 long block. So spend a little bit of extra coin and get some good heads and a matching cam and you can be well above what they did. I say build what you want. And IIRC the reason the "big dogs" go with the 1.88" rod journal is because it reduces the bearing speed actually allowing them to live longer than the 2.1" the SBC was designed with while not reducing the longevity.

again I'm not quoting anything cause it's all from memory and mine sucks sometimes.

 

ide say +1 for Karl Ellwein. Hes building my 383 ESE#33 on the site

 

very interesting. do you recall what issue?

 

The orginal article was in the Aug '09 issue and they did a follow up after it was put in a '55 chevy for the Jan '10 issue. I was wrong about the cam but it's still mile in my mind 236/238 @ .050 with .501/.501 on a 108 LSA. After they added the E-street Edelbrock heads it made 429 crank HP, which is 75 more than with the iron heads. On top of ir it is sprayed and they said the car has been well into the 9's, but it doesn't say if it was with that motor....so it's something to think about. If built properly I don't see why it couldn't embarrass a similarly built 383/396 combo.

 

well i emailed karl. lloyd elliott told me about him a while back but i lost his site when my last comp crashed. thanks for the refresher guys! his 370ci "king" has caught my interest. he is gonna whip up something for me.....
