So what are you guys doing with all this HP? I've not seen anyone post any kind of 1/4, half mile, or mile numbers? Are you just looking for the limit of the stock bottom end? Goals besides HP?

I'll be going to the track as soon as my car has a tire on it. Ordered parts today.

Are your 18's Z0 fitment or some special fitment?

Thus far we have not seen any issues.....I can say this as we have plenty of high powered engines in excess of 1000 wheel that have had engines torn down for various changes. We always disassemble them and end up putting them right back on.

So far so good.

Great to hear! This makes it worth the price alone, IMHO.

Well it most certainly isn't a "cheap" mod but its effective. We always make power with these heads. There are a few details that need to be considered when using them that add to the cost of the swap.
