Well, I'm out of "ideas".......:(

Hopefully, Crawford has a solution.

What a bummer ...... all that work ...... :cry:

Please let us know how it turns out.

I will report everything I get back for you guys to read.

Maybe you pulled a wire slightly out cuz I hear they are a tight fit??

Just my two cents, but as those blocks change the amount of air that engine can access instantly - before opening throttle. did you by any chance disconnected battery to have ECU relearn all the fuel trims and ratios? as fueling has changed, i think it should be reinitiated like that. it may help.

Any feedback from crawford already?
hopefully this thread isn't forgotten.

So today I installed the Crawford Billet Power Blocks. I took the car for a drive after I installed them, and everything seemed normal until I revved it to about 4k under load, and it seemed to stutter and not want to go above that. I took it home and tightened up the intake tube and looked over everything and it all seemed fine, so I took it out again and under a bit more throttle revved it to 4k. Same issue, but this time I got a blinking CEL that went away after a few seconds. I checked the code with my OBD reader and it's a cylinder 2 misfire. Any idea of the quickest way to fix this or find the problem? My guess is the o-ring on that cylinder has come undone and is causing a vacuum leak. Thanks in advance

By the way - my only other mod on the engine is the Perrin CAI and inlet tube. No tune.

What did you hear from crawford?

I got absolutely nothing from Crawford. They never answered any of my emails or calls. I can't say I recommend dealing with them.

Too bad ..

So that totally turns me off of buying the crawford BPBs, would money be better spent on pulleys and a front pipe then?

Crawford Performance is a joke...need some answers as well.

Yeah man go for something other than their product. They may be good engineers (I can't speak for if the product works in all cases) but they do not know how to run any sort of customer service. Just make sure to always check the return policies and you'll be fine.

But don't make this about the product, seriously. I'm sure it works great in most cases. It just didn't for me, and I got no sort of support from them when that happened.

Sorry to hear..
I would post this on their FB page. If they don't have the decency to return your calls or emails, screw 'em.

Yea, I believe they got kicked off the vendors/sponsor list here because of there service and claims at some point. Also the dyno numbers for the block seem quite embellished, I was so sure of buying this but now I'm just gonna swing on some cnt uel headers, grimmspeed gaskets and a perrin pulley for the same money as the block and proven gains.

Even more important note they never say that the power is returned to the location of the torque dip or say that you'll lose power on the top end. I think there's a ROM tutorial available that keeps you from losing all that power up top
