internal balanced stroker kits.
hello.
I search around to find a internal balanced stroker kit, not a killer kit. I dont know what to look for. I wounder if you could help me some?
Im going to run the hotcam kit, with a lt1intake. The heads will be my LPE ported 113 heads for now, next year a set of afr195 heads ar going to be installed.
The only thing i decided on is that it must be internal balanced. Dont recomend med some nascar super kit, im sure i dont need that ;)
This will be a weekend warrior, my goal is 450 hp at the crank ( with the AFR heads, 410+ with the 113 heads )
so..
What comp should i run, I whant to build for my AFR heads next year, and those got bigger chambers then my 113s, right?
Do I need fordge pistons or will hyperxxxx do ?
This car will NOT se NOS, or a supercharger, and i shift around 6000rpm
I really dont whant to spend over $1000 for the kit.
ANd I need a good compay to back me up, this kit is going to Sweden so I dont need a company with a troublesome history.
Im sure you can help me, like so many times before.

Re: internal balanced stroker kits. (devilfish)
under 1000.00 bucks is gonna be hard.... especially with forged pistons, rods and crank..
at 6k RPM I think you could get away with a cast crank (SCAN 9000 or Eagle), and hyperutectic pistons... (but dont add gas or forced induction!!). I would however, invest in some killer rods and good head, rod and main bolts!

I would go with forged pistons, just because you never know if you will want to spray it down the road. Never hurts to overbuild, well it hurts the wallet, but that's it.
I would look for an eagle cast crank, eagle H or I beam rods, and some forged pistons. Pistons will be the costliest item there, but the total should still be less than 1k.
Also, I recommend clevite77 coated bearings. When we tear down some of the motors at work for a freshen, some with 500 passes have bearings that look brand new.
You might go over the 1K limit if you're looking for a kit with bearings and rings, but should be able to get the rotating assembly for 1K, crank, rods, pistons. Everything else will be extra.
I would think the shipping is going to kill you though. :cheers:

devil, about the best deal I know of for a really decent full rotating assembly is the Scat forged crank kit. You can have your choice of rods and pistons etc. A 383 internally balanceable crank with 6" H beam rods and JE/SRP forged pistons (floaters) is about $1200 USD.

Re: internal balanced stroker kits. (JCAIRE2)
true, we ben over this. But I got so many diffrent answers. I thougt scat cranks dident have enough material on them, and that you must weld heavy material on to them.
Thanks for all feeback. Could you give me some names to those company you talk about.
Sorry if I repet myself from other topics, but this is still some confusing to me.. All this balance thing

Re: internal balanced stroker kits. (devilfish)
devil, it's real easy to get confused on this stuff, especially when you get various and sometimes conflicting information. I believe that you will want a forged crank with the 383. Many talk about the horsepower a crank can handle, but it's really all about how much torque can it handle. If you were going to just spin it at a dragstrip below 6500 or so, then IMO, you could get away with a cast crank. Running through the gears, up and down, continiously on a roadcourse, I would want a forged piece. Arguably you will probably get near 500 lbs/ft of torque out of a good 383 long intake runner engine. (like a big tube, or Superram type intake) That's Viper country torque. Believe me, you can and will melt your tires if you choose. Lastly, it was my impression that they didn't recommend drilling a cast crank and plugging in Mallory metal to internally balance it. You may want to talk to "Beach, Phil (Hoover), or Ralph on this subject. They have proven to be pretty good authorities on sucessful motor builds. They usually hang out on the "Engine Mods" Forum. Good luck!

Re: internal balanced stroker kits. (h rocks)
you can balance a cast crank.. my scan 9000 crank is balanced.. and it did require a bit (125 bucks worth) of hevay metal... but no probs... it seems to handle 400 ft/lbs ok... so far.. (I only have 5k miles on her) anyways, good luck in whatever you choose..

I have heard good things about http://www.flatlanderracing.com/ on the corvetteforum. I have never bought anything from them, however.

Re: internal balanced stroker kits. (Raistlin)
thanks..
Yes this is confusing..
WHat I hear is that for my app I should be ok with a scat crank? But then I need heavy metal to be welded to the crank, so mayby the price for a fordge crank vs a scat with heavy metal on it is around the same?

Re: internal balanced stroker kits. (JCAIRE2)
Oh, and you can spin a cast crank to 6500 reliably. A no twist forging will get you 9000 all day long.
yes yes yes. if your spinning 6500 max and making less than 500 hp dont waste ur money on a forged crank. You would be surprised how a budget motor can hold up.
