Also be aware that some piston mfgrs quote comp ratio at zero deck height and not the production .025" below deck so verify with the piston mfgr. Again, the IK200s use a fel pro 1206 intake gasket which is huge and you could have some mismatch or fitment issues with the IK200s. Call and confirm your selection with Brodix.

When balancing a crank a drilling a cast crank its like cutting through butter compared to a nice 4340 crank!!
He is a quote I did on another site
Went to the PRI Show and told Tom Leib the problem I had with there cranks and he saids I was the first to ever tell hime that, My friend that broke some near me went at told Tom the same thing I did and he told him this was the first he had heard of it and Bob pointed to me off to the side and and Mr. Leib did not know what to say.
Since then both of us have gone to forged cranks and so far no broken ones in the last 8 years.
The Callies Compstar for around 650 dollars is a dam good choice.
Here is a link from another site

I wish like hell that Dart had come out with the SHP a couple of years earlier. I was thinking my next engine would be a LSx, but now I'm no longer so sure.

. Good point on those summit heads. They look just like the Brodix heads. Anyone know if there are any major differences? I agree, the parts replacement on the side shows BRO. After a quick comparison, they are the exact replacement parts. Although, I wouldn't want something that is ported less than the Brodix that appears to be the same. May have to place a phone call..So now I have another issue(solved, but with more money, ugh)....I am very thankful that someone pointed out the performer rpm will not align with the Brodix 200cc. The power band on the performer rpm is 1500-6500 and fits under the hood if used with a low air filter. I looked up the dimensions on the weiand 8150 and it is nearly the same height. Hence, I may have to spend that extra money on a carburetor for a weiand8150 (powerband 1500-6700) instead of re-tuning that Q-jet,
. It may come out better but my budget has become tight. (after you figure in the money on the heads and rotating assembly)
Liberty Engine parts had 8 Eagle cast 383 external balance cranks break last year and all broke the snouts off and this did not happen at just one shop.
I have had guys call about replacing theh cast crank with a Forged crank but no one has ever called wanting to replace their forged crank with an cast one.
Thanks
Thanks
Most of the time we will try to fit an old cap up so we can just do a line hone and that runs about 185.00 dollars.
If its not cracked and sonic tests good I would keep it.






OK, this is going to fly against what I did & what a lot of guys recommend, but you are building a street engine & need to have a fun car without going broke.
1. Use Dad's block (I would prefer that you find a roller block)
2. Forget the Brodix heads, Procomps are $600 on fleabay. You don't need the flow that the bigger heads will give you. Many people run Procomps & like them. Clean up any flashing & run. They are probably much better than the fuelie heads we all had wet dreams about in past days. http://cgi.ebay.com/ebaymotors/350-3...Q5fAccessories
3. Get a balance Eagle cast kit on fleabay - $520. For what you are building hyperteutectic are fine, the factory uses them. http://cgi.ebay.com/ebaymotors/EAGLE...3A1|240%3A1318
4. Get a Qjet intake of your choice & use your carb
5. Go stock on everything else, maybe a 1 qt larger pan
6. Find the 2 1/2" rams horn exhaust manifolds (fleabay)
7. After the car is running & you are enjoying it you go for things like a MSD dizzy, headers, exhaust.





I originally was going to just rebuild the 350 (but you know how that goes, lol). So, I wouldn't mind going hydraulic or solid, even if it did cost me 50hp as opposed to roller. I see the main thing here being going roller...to be, or not to be roller.

I'm with Carl, why risk $500 or more of block work on a cheap cast crank. Plenty of broken SCAT cast cranks, even Lars reported seeing them occuring.
I was just eating thinking about why I didn't want to go roller. I had read that you can float a lifter ( i know i know Scott...stop reading other sites - that was something I read a week ago). Anyhow, I am not going to have rpm's reving that high. Hence, roller would be the way to go to increase my torque band like mentioned above. I would have more money to spend .... but I am looking to get a ring afte summer....I would be in trouble if she found out how much I am spending, LOL.
Also, I realized the rotating assembly is cheaper for the roller block. More money saved, yay. So, I am partially where I started except a roller block.

The brodix 200 head has been used with the edlebrock rpm manifolds by forum members and by chevy high perfomamce ragazine in a manifold test. just use the rpm Q-Jet manifold #7104.
Your Q-jet has a 750 cfm capacity its plenty big enough for any reasonable rpm 383, no sense if your on a budget having to spend several hundred for another carb.
A soild flat tappit is inexpensive will make better power then a hydraulic flat tappit.
Buy a scat IB forged crank, forged pistons rotating kit, then you are pretty much set for any kind of power level you would like to have now or in the future.
Use the 200 runner head its fine for a 383, gives beathing for any future upgrades in power, you use the 180 head your stuck with it.
