Asked by BillZ06 Jan 06, 2008 at 09:20 PM about the 1991 GMC Syclone

Question type: Car Customization

I have a 10,500 mile Syclone that apparently has been sitting too much and needs a rebuild.  Do you have a receipe for 500 rear wheel horsepower?
And approximate cost for parts, labor, etc.?
Thanks,
Bill

I would suggest reading up on what some of the engine guys are doing in some of the trade magazines. They regularly have builds like this.
