As a private builder I can do a lot of things... But I think the 1.1hp/inch, for less than $16/hp, compelely dyno'd and ready to go is a next-to-impossible package to do for anybody. The 496 I'm assembling now is low budget. It's a previously machined 383 block plus all his other ancillary components that have only 800 miles on them. I did a little more to it, but the block was basically set except for a sonic test and main studs. With the new heads (decently ported Stealths he basically stole from a pro shop), new cam, and rotating kit - he's into it for close to $5K. Nevermind the dyno time which is another $600 plus supplies. So - what do you already have? If you have a wish and some cash - you frankly don't have enough and I'd really question the ability to have anyone do it for your limit. You cannot build to play with the big boys on a cub scout budget unless you have a boatload of the right parts already. The power requirements are no big deal although the hydraulic lifter would be an issue for me given the vacuum requirements. The budget is way off base IMO.
