If you want to haul up to lake Tahoe, Advantage Marine is a great shop. They do all high performance work - honest and good to work with.

Maybe consider tow boat to So. CA and use Teague. You know it will be done right.

Or drag it to GT Performance. Those guys do some nice, nice work. Dyno, EFI tuning, you name it Gary can build or rebuild it.

Call "Motor Machine" in Sac. They just did a set of hp 500's for a friend of mine. Talk to Don the owner.

We would be happy to help. We have years of experience with the 500 hp EFI . We also can tune your ECU. Our pricing is reasonable & we stand behind our product. We offer all our work with a money back guarentee. Feel free to call our shop (530) 550-1638 or check our websites www.advantagemarine.co or www.pigironracing.com
