the 440ci made nice power but i think tigger has a better setup for the $.he made 707 on 93 pump gas.dart uses aftermarket block,big ci,and c14 race fuel and super vic intake.lets put tigger engine on c14 and a super vic 4500 and see what the power difference would be

The numbers are nice BUT.... those numbers have been hit multiple times by Chris Frank with his LS7 brodix and RHS heads, and Chris hits those numbers on street cars!
this thread leaves a lot of questions....
1. thinned out oil
2. pump gas? how much octane [ I assume 93]
3. cam? don't need the exact details on spec but is that combo conducive to street driving or all out race?
Again Chris has been hitting these numbers on a soft aggressive cam that makes the package streetable.
these guys are on the right track but there is still work to be done.

Hey guys, Our LS3 Dart heads will be in the $3400 price point. They flow over 400cfm on the intake and 270 plus on the exhaust. We found that the dart head comes as cast at 280cc and flowed 340@.700 on intake and 230 on the exhaust@.700 on our flow bench strait from dart. Our stage 1 stk casting ls3 head is 280cc and flows 375@.650 and 255@.650. So we decided that the dart head would best be used in a larger CI application with a solid roller camshaft. So our head is designed for larger bores 4.100 bigger to make big power in race applications. We will offer a version that fits on a small bore(4.065), but we feel that a stock 821/823 casting will still perform better on the smaller bores.I'll get some pics posted later.

The Dart heads run pretty good on my 4.005" bore engine:

Not saying they won't perform good on small bore I just prefer something more efficient. If they are used with the stock plastic intake or fast, msd they won't make the power as a more efficient head will. the dart likes more aggressive intake setups.
