Camshaft help?

[raymond73]

I would get bullet called very soon for December. For technical help we ask for Tim Goolsby, but I would guess anyone would know how far out they are w flat tappets. I think it's been hit n miss on cam cores.

I Will do that.... Thanks for all help....

Stay with 705 over those two.. The bigger one probably will make a little more power but longevity is questionable. I don't think you will do any better for a hydraulic that what you have.

Bummer that Bullet is that far back. A few years back..they got us Cams in a week. Your right... Pickens are slim if you want it in december.

As far as a solids ready to ship:
Summit has a xtq solid grind available The XTQ would be quicker and make more power then the 705. I would rather have it on 110lsa though for what you are doing.

Could call crower...see how far out they are...may have one in stock? Not thrilled w what they offer though off the shelf, custom be likely same time as bullet.

Hi and thanks for all help i have to ask about dynamic compression with this 705.. We have pump gas like your 91 octane.. And My static compression Will be at 10.7 and if i use a calculator on this will the dynamic be 9.56 if i do this right... I have heard thats way to mutch on pump??? Any on this?

Sorry My fault i forgot to ad 15 degree on that @50 abdc number.... IT Will be 8.7:1...

I dont think your plugging in the correct numbers. To find a dcr use the seat timing, .050 number dcr doesn't mean much.
Look on your cam card for the seat timing. Advertised is 284, actual should be 287 for 705voodoo.
The voodoo is assymetric, meaning they close the intake valve 4-5 degrees later. So the number if it were not assymetric is 69.5. The actual should be about 73.5-74.5 (since it's assymetric).
Should be looking at a DCR in the mid 7's. Plug in your details. Wallace racing has a good site.

[Curiousyellow71]

925 Looks like the same spring as what you already have. One suggestion install a .020 shim get the seat pressure around 130-140. Imo.. 120 isn't enough.
