Re: ZR-1 price variations?
I would be surprised if you got 125HP from just those mods... 450CHP maybe. I would think a 475-500chp LT4 would put a hurting on a sub 500HP LT5, on everything under 120mph.
I love the LT5, but the cost of making an LT4 fast is just so cheap compared to the LT5.
A full exhaust and 4:10 would be the most I would do to a Z personally.
