I wanted to take my 94 LT-1 and convert it to an LT-4. The only questions I have are instead of ordering the whole kit can I go to a junk yard and find a scraped vette with an LT-4 and buy the manifold, cam, rockers, etc. Basically are the sizes the same, or when the conversion parts came out they were engineered to do the same thing and look the same only different measurements. Granted its a 5.7 liter block but maybe the cast for the vette block is not an exact replica only similar in many ways.....Please get back to me if you are certain....and not almost certain.....to really break has anyone else done this themselves....
