my cam part number is 249-12-609-5. would i be safe running 64cc chambers without going to high in compression? i would love to run 64cc's but im a little worried about it.

as for the motor specs...

bore-4.030
stroke-3.480
rod length is standard for a 350, presuming 5.7
deck hight and piston dome volume is unknown.

most of the reason why the performer rpm's were calling my name is because they were complete aluminum heads that cost less hten a grand. if anyone knows of better assembled alumin heads for less then a grand that would be helpful.

So i was jsut looking at DART's Iron Eagle Platinums. Particularly the 200cc intake runner, straight plug with 64cc chambers. cost $499 each, which is my limit. do you prefer these heads over edelbrocks performer rpm's?

Please don't go beyond 180cc you will hate the set up. There are new aluminum heads on Ebay that are the same price that are in the 180 range. Don't think bigger is better in you're case. The cam you are running will love a GOOD chamber design and a 180cc intake. I added a URL so you could see what a great design combustion chamber looks like in my previos post. Please look at the chambers only. the intake cc's are too much for you're application. You can get a great set of aluminum heads with the correct combustion chambers and 180cc intakes for under $1000.00 a set ready to go. Adam

I would run the Iron Eagles over Edelbrock any day. Look at my earlier post because those ports will make the mouse a mole Rolling Eyes

Hell no!!!
Even if you had 0 deck and -5cc piston the compression is still low.

I still dont know what you would have agianst the rpm head; but just to refresh here is a picture of the rpm's chamber, maby im wrong but thats a kidney bean if ive ever seen one. 1000 bucks complete with a 170cc runner, a 64cc chamber, and the weight reduction,this is a good coice for the combo

Big time different from the heads that mock the LT1 that are on the market. Kidney v/s heart. It doesn't seem much until quench comes into play. Quench on both sides of the combustion camber will force all the available air/fuel to the place it has to ignite. Heart shape is the only one I would use period. Adam

Comp cam's doesn't list the specs for the cam online. Do you have the cam card?
The deck height, and piston dome volume need to be known. I'd suggest checking what you have before you buy. Otherwise you're just guessing.

Below is the output for some guesstimates on your engine. Assuming these are correct your cam should be in the range of IVC from 60-67 degrees ABDC.

Code:
 Bore 4.03 (inches)
Stroke 3.48 (inches)
Rod Length 5.7 (inches)
Cyl. Head Vol. 64 (cc)
Deck Height 0.025 (inches)
Head Gasket Bore 4.1 (inches)
Head Gasket Thickness 0.015 (inches)
Piston to Cyl. Wall Clearance 0.003 (inches)
Top Ring Land Height 0.25 (inches)
Piston Dome Vol. -6.2 (cc)

Compression Ratio:
10.24 : 1

Displacement:
355.1(ci), 5.8 (liters)

Bore / Stroke Ratio:
1.158 : 1

Rod / Stroke Ratio:
1.638 : 1

IVC ( ABDC)   Dynamic Stroke (inches)    DCR
55   2.919   8.751 : 1

Std deck on a sbc is 9.025", however I had mine decked to 9.00" for compression which with the 6" rod and KB pistons put the piston out of the hole .005". If He's going to just replace the heads and cam in the car(good luck with doing the cam in a 3rd gen F-body) and not take apart the short block, I would say get a small chamber and maybe a .016" steel shim gasket to bump compression. One thing though..no matter what you do, if you are changing the cam get a dial indicator, degree wheel, light"checking valve springs" and make sure to carefully degree in your cam before you fire the engine. If you don't it will probably not run the best, at the worst it will destroy pushrods, valves or pistons. Don't assume that you can install an aftermarket cam "straight up" like a stock cam. My cam had to be advanced 3 degrees to keep from mashing the valve into the piston. If you don't know how to degree a cam find someone to teach you, it's invaluable knowledge. I wasn't sure about it and I had the guy that builds Doug Herberts top fuel engines tutor me over the phone..saved me from screwing up a bunch of expensive parts!

no infact im not going to buy a new cam. the cam jsut recently got examined along with the lifters and its still in brand new condition. basically jsut a head replacement. i have been trying to find aluminum heads 64cc chambers, 2.02/1.6 valves and less then 200cc, but having trouble finding them for less then or right at $1000. as for the head gaskets, i did infact find the felpro #1010's and that should be allset. if anyone can help me find a link to some complete heads that i need, and also does anyone know the torque specs for heads on a 76 small block 350? thanks i really do appreciate the help. whether they are edelbrock rpms or not, overall im jsut looking for a head that will breather better hten what i have, give more compression, and cost less then a grand.

The start up companies are bitchen on Ebay with their prices. The heads have the same combustion chamber as the Pro Action heads. The ports are very good also.
