Here is the cold start on our custom Whiplash LT Camshaft on Chase's A10 ZL1 with our X1000 package on it, putting down 870whp on our Mustang dyno!

You can buy the same cam direct from our store:

A shop down in Houston broke the fuel pump with the 50% lobe on one of my parts customer's LT4 CTS V3s. Our 38% is about the highest you can go and even then you have to measure the preload on the pump and we also run the stronger fuel pump springs and provide ARP studs for the fuel pump.

Is that stronger fuel pump spring something we can buy?

Thanks everyone I'm currently waiting for the Stainless Works Exhaust to come in then after a few more miles I will be getting the Cam and all the other goodies that go with it. Luckily we have a shop right here that dyno tunes so she will get a custom tune along with it.

Great question, bud. Hopefully someone answers it

So far so good Brantley. I haven't had any temp problems since the Stage 3 cam install. I did have a prospeed heat exchanger installed by Ryne @ CMS and my car runs 4-5 degree a cooler than it did before the cam install. I drove 400 miles from LA to Home and Sat in LA traffic for hours as well. I do plan on installing a Converter from Circle D Specialties but they still have to make one for our cars. There's no Converter for the A10 available yet.
