Before I start I did research before posting this! Looking for supertech and Brian crower, And most forums I read people use only springs with oem retainers rev to 9k with no problems on stage 1 or 2 cams
But the price different from each other BC 240 and ST 300 supposedly they are made by same manufacturer with same material!

Now I have a d16z6 doing N/A with parts I had sitting for a year because I got my hands on a b series now I want to build it!
P29 pistons .40 over on stock rods with arp rod bolts
Thick cometic head gasket
Blox stage 3 cam
Skunk intake mani with 65mm throttle
Custom made headers


I just need the springs and retainers! I was about to buy the BC but not sure how they would handle the stage 3 cam
supertech I have in my b series and they hold my cams pretty well

What you guys think? Is BC waist of my money or spend the difference and get Supertech? Should I get only springs or get springs with retainers? Again running stage 3 cam on z6 head

Thanks

 

Contact my brother at rdspring2@AOL.com think we have more of the springs I'm running in my z6 head with 455 lift cams just tell him how large your cam is how high your rpm limit he will guide u on installed heights and coil bind issues that u may need retainers

 

Thanks I'll check that out

And what springs you think would he bet

 

We design our own spring retainers head and valve work we can setup your entire head if you would like,port work valve work and they are some of the best in the world they run them Indy cars NASCAR every form of racing even motorized racing bar stools and drag lawn mowers. Lol.. depending on cam size and desired rpm we can make the retainers for proper seat pressure and spring travel. I believe the stock spring at stock installed heigth of 1.97 can lift 430 then it binds its seat pressure is around 35pounds.

 

how much you guys charge for that same price range as the supertech and crower? im a little on a budget right now most ill spend is for supertech

i was just wondering to which ones would do the work for the blox stage 3 cam trying to get this build done by next week for import wars lol

 

Or last question

On Blox stage 3 cam what springs would you guys recommend? dont know the specs just yet but as soon as i find it ill post it

 

D-series Stage III SOHC VTEC Camshafts Specs:
Intake (lift / duration) 0.442" / 239
Exhaust (lift / duration) 0.468" / 226

 

The springs are 180.00 without retainers but they are compatible with the stock ones they will be more than sufficient to handle that can looks like our running a nitrous grind do u have nos

 

How much with both springs and retainers?

Yeah 20lb bottle wet probably 50 shot not sure yet

 

350.00 for spring kit with ti retainers

 

The BCs or supertech should work fine for your application we are more expensive because we get exotic bar alloys from japan as well as everything is made in the USA baby! The retainers in my price would be a comp cam retainer if you wanted our retainer the price would double due to the ti alloy my grandpa designed . Not to sure if you will be able to take full advantage of that cam without head work and a larger shot. I would recommend running a 75shot with 6 degrees of retard do a short 2nd gear pull then check ALL the plugs. THE MOST IMPORTANT step you need to worry about is the cam break in the EPA has taken out most of the zinc and phosphorus out of the oil which is there to let the valvetrain live. Make sure you get some comp cams cam break in oil additive or another similar zinc additive from your local hot rod shop. I just talked to a guy who has ruined two sets of those cams and his valvetrain but these failures are not just limited to that brand.
