Before you sell the setup short I would take and run the car in the 1/4. That will be the true results and you will get a good idea on the power it's making. Like I said before I made 420 on a Dynojet but run low 10's@130+. However, I have seen hundreds of cars make more power than me and run 15MPH slower in the 1/4.

Car is still in the shop, I came across a REALLY good deal on kooks true dual system which had less than 100miles on it so I opted for that in stead of my ARH LT's and custom Y pipe. Had the shop recheck all the valvetrain since I was having them put on the new roller rockers. Turns out that my pushrods were the wrong size (too short I believe) Ill find out mroe details later this evening. MAF is installed, also going to have some polly MM and Trans mount put in since the old exhaust is coming out. Makes life alot easier there. Cant wait to compare the numbers once back on the dyno!

That's what I was wondering. How do you have a "pro" shop set up a car with valve train problems. Stupid old me had no problems setting up mine. At 10.25 you sure are on the low side. Must have pretty large chambers.

Did that shop originally just toss in a set of pushrods without checking the pushrod length the first time when installing the heads, etc? If that's the case, that is not exceptable from an experienced shop. Checking pushrod length is very simple and does not take much time at all. This is one thing an experienced shop should never make a mistake on.
I would have problems trusting that shop with my car

Just got off the phone. Pushrods were to short. They first put 7.450's in there......now they just put in 7.525's. Also was told all other valvetrain parts were not damaged. PRC 227s with TSP Tsunami, seems like a big jump in PR size. Should get some good flow numbers now....

Did they give any reasons for their **** up? Not that there's a good excuse..but still..that's HUGE jump in pr length. I would still keep an eye on your valvetrain..they didn't even take the time to check pr length on the initial install so how thorough were they when they were inspecting the parts that had "no damage?"
