4v Compression Ratio's
Some of you might have saw my thread about my Bullitt's 2v ticking. After bore scoping and looking at the pistons, I have at least one with a couple nicks right on the edge, so I am going to pull it apart and take a better look. Well since it will be apart I thinking of maybe switching to a 4v.
I have a chance to purchase a full 4v engine with a 5.0 stroker kit. Engine has about 20,000 miles on it he says. Its a teksid block with B heads, 96-98 Cobra intake. I'm not sure of what CC pistons are in it but he claims it should be at 12.5.1 compression Ratio. I'm not even sure how you get the C/R that high. All the storker kits I can find only show the C/R being around 10.1, even with a low CC piston. Obviously 12.5.1 is way to high to be able to put my Novi 2000 on. What will I have to do to drop the compression? Will swapping to C heads lower me down enough to put boost on it? Or will I have to replace the pistons?
Any advice would be greatly appreciated. Thanks.
