Hey hows it going everyone, I know the CTR piston in a GSR topic has been covevered but heres another question that isnt covered. Most of you are going to say that I should just clay the motor, in which I might just do but I want a little feedback.

WILL THIS CLEAR? :
-CTR .25 over pistons
-GSR BLOCK
-GSR HEAD
-SKUNK2 stage 3 cams
-OEM 3 ply headgasket
-slight "skimmed kiss" on surface of the head (cleaning)

many say yes it will clear but I just need some feedback...preferable from ones who have this set up already. thanks guys....

 

ttt? no one knows or no one has this set up?

 

better to be safe than sorry....clay the thing...

 

indeed thats what i will do anyways, just incase but kinda wanted opinions. theres a 0.40 clearence i heard for the pistons however i guess i should just clay the thing!

 

don't know how the lobes compare, but i had a similar setup w/ crower stage 3 cams... dunno if its from rod stretch or what not, but i had piston to head contact.... the " in" and the arrow on the pct pistons were indented into the head.... dunno if this info is relevant for you but just letting you know....keep in mind that this setup was driven for nearly 3 years, and ran great the first 2 years....

Wow, interesting, so im taking it that your valves bent becuase the "in" symbol is on the flatter portion of the pistons?

skunk2 stage3
IN. 0.504, 270
EX. 0.465, 279

crower stage3
Int- 263 mid
Exh-255 mid
lift:
Int- 468 mid
Exh-468 mid

if im not mistaking the skunks are "bigger"

You've failed to notice something grasshopper!

Crower Measures their cam specs @.050 and Skunk2 measures @ 1mm.

therefore you have to convert crower's specs to mm.

-Skunk2 Stage III -
INTAKE lift- 12.8 mm, duration 270 @ 1mm
EXHAUST lift - 11.8 mm, duration 279 @ 1mm

Crower Stage III's
- 63403

INTAKE lift - 11.98 mm, duration 246 @1mm
EXHAUST lift - 11.83 mm, duration 238 @1mm

Your were right that the skunks are bigger, yet they are bigger than what you thought!

 

arent your cams too big for your motor?

 

you'll be fine with those cams ... if cleanup is 5 thou or under. the CTR pistons have good valve reliefs.

thanks guys for your in-put. The stage3's are pretty large and the head was barely "kissed" so its for sure under 5thou the stage3's are great cams in my opinion,
