Well the decision had been made about our 406 in the Camaro, It has about 100 runs on it at this given time, no issues thus far, Here is the thread on the Camaro 406:
http://www.chevelles.com/forums/showthread.php?t=219983

It will be a 505cid engine :D

But we also located a good usable 454 block. We are gonna have it sonic tested {cylider walls} then we will install Milodon splayed main caps, Fill the water jackets with Hardblok, 4340 crank, 4340 steel rods or Aluminum {decision not made here} and 2618 forged pistons which will yield on paper about 14.1:1, we will have to CC everything out to see what we have in the engine after mock up and adjustments

We have a set of fully ported heads that flow good, they were ported by ladd porting, http://www.laddporting.com/ , We will start with these then try a set of fully cnc ported heads from Dart

It will for sure be a solid roller cam and lifters. Top rpm should be about 7,200-7,400rpm. If everything works together we think we should be able to hit low 9's maybe in the 8's but that will take some tuning as the 406 took some time to go from 10.88-10.94 to 10.40's

It will have the following parts thus far :
- http://www.kingbearings.com/ We really like the King bearings - very high quality

- http://kb-silvolite.com/forged.php?action=details&P_id=360 We will be using these pistons as they are very nice quality and not to mention the KB Hyper's are excellent

- http://www.totalseal.com/ Total Seal has very good tech guys, we have tried their std moly ring and seems to be pretty good so we will be using their better line of rings, Gold Finish which is close to the Diamond Finish rings but more for the bracket racer they say

- we will be using one of the following heads, one is cnc ported 335cc aluminum and the other is cast iron 345cc

OR

http://www.dartheads.com/products/h...eads/bbc-iron-heads/bbc-iron-eagle-heads.html

We will be using Crane Cams for Cam and Lifters, H-11 springs, rockers and more on this application

If anybody has any ideas on what would be some interesting testing or ideas please let us know, post it

Sounds like a fun motor project Butch! :thumbsup:

If interested...I've got a Jomar girdle with nuts, a set of Comp Pro Magnum 1.7 rockers, and a set of Isky Red Zones (rebuildable) recently removed from my BB that I'll let go cheap to help the project out...;)

The new Brodix Head Hunter series and the matching oval port manifold are worth about 50-80 H.P. over the 335 CNC Dart heads. You might as well get the best you can the first time around, not something that is already out of date. Ed Bigley went with the 332cc Brodix -3Xtras CNC's and his 522 made 894 H.P. I think our 540 had about 830 H.P. with the little "Dart 335 CNCs". I have had several different sets of heads and been around lots of others and the AFR 357 CNCs make more power than the Darts, 335s or 355s. I still think the new oval port Brodix's will make the most power right now. P.S...... There are better springs than the H-11 springs too, the newer PAC 1300 series are said to "not loose" any pressure from repeated heating and cooling cycles. They are also available in smaller diameters (1.50"-1.55") to avoid interference with the rocker arms like the stronger H-11 spring which typically have (1.65"- 1.70") diameters. The best stud girdles on the market are the BLPs, they have seperate bars for intake valves and exhaust valves, eack valve can be adjusted without loosening the adjacent valves, (try that with the typical bargain basement stud girdle) and can be used on any big block head with the same valve angle cant and 4.84 bore centers. P.S.#2.... You car is really light but will be about 175 lbs. heavier with the Dart big block in it. The block is about 100 lbs. heavier than a small block before the heads. The Dart 335 CNC heads are the lightest i've seen in the way of aftermarket heads at about 27.5 lbs. each plus rockers, studs, etc.

Its a GM block thats gonna be getting Milodon splayed caps installed and the water jackets filled with Hardblok

The H-11 Springs have never let me down, I have looked into the PAC for my Small Block but have not found many people that have used them. Now, are the PAC springs the same as the old Comp Cams Pro Pac springs? If so, those were very good.
