Nice work!! Glad to see you guys are a sponsor here,will keep you guys in mind on my next round of mods

Damn, nice power. I can't believe you gained 43rwhp over a FAST going to a sheet metal intake! That is just awesome, makes me very happy I decided to spend the extra and get a beck.

Seems a little weak dont you think? Nawww just kidding great lookin sleeper and big power to boot.!!!

Remember we actually modified the Beck intake. I don't know how much that helped. The manifold was beautiful but it was designed for a Camaro and it didn't fit under the GTO's hood. The hood on the GTO has a good swoop to it. We cut her down and also opened up the inside behind the 100mm TB opening. There was a big hump in there. I believe we removed over an inch of material causing a big airflow speed bump inside. When we were done you could put your arm inside and before you couldn't get your hand in. Beck makes a great manifold but the clearance issues made this one a bit more involved. All said it did massively change the characteristics of the engine. Almost like a different motor.

who is the car for where are they from?

Why do you ask? You will see it in the Chicago area if you are near (At the track and such). Or if you have any questions on the build I can answer most, and I know the owner will contact you if interested.

That's an all around nice package.

Awesome job guys & Big Congrats :cheers:

Time to Back it up with some low ETs :devil:

peace

Awesome numbers great work and congrats to the owner.

The car will fly at the track is it a full weight car??

Full weight and some from the block....

Why does the video tag say 700+ hp?

At the crank......715/630

Love the sleeper look of the car LOL! Amazing job, props to yall. How much maintence is required with it being a solid roller setup....or what would be the extra maintence if daily driven due to the solid roller setup?

In the LSX block I bet we don't see much adjustment after the whole season. It is a very rigid block. I would check after every summer if it was mine. Some don't and some do. Believe it or not the solid rollers are quieter than the hydraulics. IMO

how much did the beck set you back ?

Very nice.

Wow, that thing sounds wicked!

The manifold was $2400 but we put another $700 or so in mods in it. Especially trying to get her to fit under the GTO hood. It is designed for the F-bodies. The GTO hood actually slopes harder in the front. We looked at Hogans also and they were about $600 more but maybe we wouldn't have modified it. Who knows. Both companies make a nice piece IMO and sometimes worth every penny, like in this case....

'Trust' it has a real NASCAR sound to it in the higher rpm ranges. You hit it on the head. It really does sound wicked! You should here her without those chambered mufflers...
