I just wanted to post my experience with powerbyace.com. As you may know there is no phone number on the site that you can call. Your only options to contact them as stated on their site is email or postal mail. I chose email and within a few days received a reply. After a few more emails to him I was given a number to call and had a fairly long conversation with the owner. Also, the only method of payment is postal or other money order as well as check.
I know some are wondering whether the company is legit. It is! I am going to paraphrase the conversation I had with the owner. He is retired from the automotive industry where he has been engineering/designing parts for his entire lifetime. He is financially secure, retired and operates his business to keep himself occupied. He moved to a low cost area of the country. He owns the property, the building, machinery, etc. outright so he has little overhead. He is able to do something he likes and make some extra money.
I decided to buy the lsx vega/monza parts he offers because I feel that it is far cheaper to buy them now rather than in the future potentially have to pay someone to fabricate the parts if they are no longer available, although he assures me he is not going anywhere.
The parts I received are in my opinion equal to or better than parts I have seen from other companies. They could just as easily have been from moroso, hooker, etc. I cannot review fitment as my car is in another state and will not have it at my house until next summer the earliest but I have spoken to people who used his sbc vega/monza swap parts and they were happy with fitment. I believe 9secondvega on this site used his lsx headers but not the mounts. pan kit, etc. I also found positive reviews on other sites for his chevy luv swap mounts and headers.
I bought the lsx to 4cyl adapter mounts. If installing these on a v6 v8 car then there is an additional kit needed that mimics the plates that are welded to the stock unibody that would have originally accepted the factory 4cyl mounts. I also bought a set of adapters that allow an ls engine to be used with the stock v8 mounts. I bought both because I am going to use exhaust manifolds (hooker, cpp, ctsv, or 98 fbody) and I may need the additional clearance that the factory v8 monza mounts afford as they sit further forward on the engine. I am pretty sure his lsx to 4cyl mounts will afford the clearance I need but bought both just in case. I bought 2 of the oil pan modification kits and pickups (at some point I may build a second car). He offers transmission and engine mount shims which can be used to fine tune driveline angles or clearance - they were cheap and not readily available. Everything came with detailed installation instructions. He also refunded a shipping overcharge.
At present the only transmission cross member he offers is for the 71-74 vega. He does not have a working design that takes into account the changes that took place to the floor pan in 75 for the catalytic converter or the changes that occurred on the 76-80 cars. He has shown an interest in working with me to develop a transmission cross member for my 75 monza (The floor pan is unique in relation to earlier or later cars) that will allow t56, 4l60e and other transmissions to be installed. If the transmission cross member ends up panning out I have some other ideas I am considering discussing with him (hydraulic clutch conversion, rearend brackets with additional material on the upper brackets that can be used to raise the upper control arm mounting points, traction bars, adjustable front control arms, 76-80 transmission cross member, 8" dual diaphragm brake booster to firewall bracket, etc.).
