Default Modding a High Milage Car

Okay, some of you know I'm currently looking for my first vette, a C5 to be exact. My spending limit isn't exactly the largest amount, so I'm going to be limited on what I can find/buy in my price range. My question is, is it safe/okay to mod high milage cars? I'm talking heads and cam on a 70k miles and up car. And obviously I don't have a huge budget... so this would happen quite a while after I purchase one(I'll just be thankful to own one... mods really will be the least of my worries)... which means even more miles would be put on the car.


If its highly NOT recommended to mod higher milage cars, what exactly would I be looking at doing to eventually end up with a 450 - 500 rwhp DD? Engine wise. I'm trying to find cars in the 40k mile range but generally they are out of my range or snatched up quickly.


I don't mean to sound so much like just a kid who wants to go fast... I mean I do, but I want to do it right. Theres no point in me putting my hard earn cash into a car and have it give out on me a year or two down the road b/c I did it the halfass way. I'm just trying to learn for my future plans.


Please excuse my noobness.

70K is nothing if the car had regular oil changes. The clutch, brakes and tires are the only wear items I would begin to worry about. These motors can go several hundred thousand miles no problem. Most look new inside at 100,000 if the oil is changed regularly.

Well, I agree generally the most obvious of wear I see on these higher milage cars is the seats(cheap leather), tires, and for some rocker panels and front ends with small chips.



Anyone elses opinion would be greatly appreciated.

The LS1 is one tough engine. Assuming that all of the routine maintenance was performed in a timely manner you should be able to mod it without too many worries. The sage advice that always applies is buy the the lowest mileage car you can afford.

I wouldn't shy away from a slightly older car with lower mileage, versus a newer car with higher mileage.
