Thread: Custom grind blower cam

Located in South Haven MI.

$200 Shipped

Specs: 218/ 224 duration 330 / 335 lobe lift 528/526 valve lift 115 LSA

From what i know, this cam used to be a IS3 blower cam that was reground by its previous owner (orangel67). I recently pulled it out of my old dd/strip car. Since i went turbo id like to put in a turbo specific cam so the blower cam has to go. There are signs of wear like most used cams but, there is no pitting or gouging. Its ready to run. I added a video of how the idle is at the bottom. Its on Chris' car not mine. When it was installed in my engine it was ran for under an hour total.

Bump, price drop

Tempting but I don't want to run a double roller. Were your heads stock?

Yeah they were stock with 90# springs and the stock chain. It was run with a double roller before but that's because he was still using the setup from when it was an is3

I forgot to mention that I was using Manley modded retainers and viton valve seals

Yeah that's just too much for what I'm putting in the Fiero. Still looking for a VS or XP cam.

I have an xp that I'll be selling after a while. It all depends on when I can pull it out of my dd to throw in a turbo cam

Cool let me know. The one XP I got from here is all torn the F up on one of the lobes. I'm not in a hurry either. maybe in a month or two?

Thats the plan

Update: this cam can be used with stock heads. You'll need some modded retainers though (just like with an xp cam)

Was the price dropped to 200 or is it lower then 200?

It was dropped from 250 Shipped to 200 Shipped. I just edited the first post so people see it when they read the description.

So it has duration similar to the IS2 cam and lift of a s1x from a IS3 ? Very intriguing. Did Chris make any runs on this ?
sounds like a great hybrid cam for someone on stock heads.
I would still use modded retainers and seals of course

As far as I know he never made any runs on the cam but he did say it made more power than he had felt out of the car before and it pulled hard to his 7k shifts.

ok thanks ill consider it

wait a minute here supposedly this is a reground IS3 cam?

s1x is reccomended to have 105# springs

IS2 is reccomended to have 105# or 130# springs

IS3 is reccomended to have 130# springs

basically my point is i think running this cam with 90# springs wouldnt be a very good idea.

hell my s1x was on at least 105# springs and id use notbing less than 105# springs or maybe even use 130# to make sure it doesnt float the valves.

the above statement of using 90s on this cam sure doesnt seem like enough spring to me........

i bet it would rev right past 7k on some wimpy 90# springs lol

Well in respect to the seller, this forum tends to favor the 90# springs when using the stock timing chain.

Will you potenially get valve float ? Maybe. But hey you don't need to go to a DR chain - is the general consensus

My base tune for the car had stockish shift points to avoid valve float. I planned on raising it when I upgraded to 130s.

all i was pointing out is i wouldnt run anything less than 105# springs and yes my s1x was on 105s and ti retainers and stock timing chain.

as mentioned above by james id run a fresh stock chain on an xp cam too its not much different than a s1x spec wise.
