Honestly? Building engines with that kind of output is not for the garage builder. You can certainly work with a local builder and pick and choose your parts, but building a moderate street engine (especially a Chevy, which is an easier build than most) is one thing, and putting together a high-revving, 1+ HP per cube engine for a light car is a lot more demanding.

Anyone can bolt the parts together. Only those with experience can get the most out of the combination, including a lifespan measured in thousands of miles.

PS- 12.5:1 was a wonderful thing back in the days of 102 octane pump gas. You will not be able to drive it on anything but Unocal 105 (at $8 a gallone) or pump 91 with a 'spensive bottle of octane boost in it. Think it through - nearly all of us have about 10-10.5:1 compression for a reason.
