The question was how much for a Shelby Aluminum-based motor.
Well, the threadstarter certainly didn't ask for an [un]educated guess by someone playing with numbers, kunick.
With all due respect, I'm not sure what Rick has offered up since his sig refers to a 428. If it is an aluminum block, smart shopping may very well have resulted in a great deal--and doing it yourself does save quite a bundle. Realistic? That's for the buyer to determine based upon the approach he or she wishes to take. There are variances all over the place.
Pat noted Shelby's stated price for a complete motor.
Bill commented on realistic labor costs, and noted the quandry one might have in putting certain parts in a motor with basic costs already being significant.
JBaird's (the only builder to respond--many thanks) price for a Shelby stroked motor is not substantially different than what I laid out.
And I know George at Gessford is in the same ballpark for the Shelby-block motors.
Ultimate motor--oh hell no! They cost a whole bunch more. Mine is just a good build. Set forth the specifics because I got tired of the wide range of guesses I've seen prooffered everytime somebody asks about this.
