Default Head and cam swap and mileage

I have a 2002 M6 Firehawk with 14500 miles. I want to do a head and cam swap but I am worried that I may have too many miles to do it. Can I do it without having to rebuild the engine or upgrade any other parts of the engine?

You'll be fine. I did my swap at 29,000. Absolutely no problems. There are a lot of guys modding 90,000+ mile engines on here.

14,500 is barely broke in good.

Should be easier, you won't even have to change chain or oil pump. Piece of cake.

dude there is no reason that should be an issue. 14500? if you had ten times that, then we would say it would be a problem!

There are many 145K + ls1s , both modded and unmodded, that are running quite strong. There was a turbo 98 formula a sponsor had with 130K pushing ~800 RWHP or so on the stock bottom end for hundreds of pulls before the stock bottom end let go.

Guys the miles on a motor are irrelative.

This is my recomendation upon wanting internal modding:

1- Do a compression test
2- Do a leakdown test

Once you have the results on these two, you make the decision on how to proceed.

This man knows a lot, and this is probably the best advice youll even hear on the subject.

I will also add, that if youve owned you car the entire time, you kow exactly what it's been through. If youve put it through hell and back, dont expect it to live forever with new mods. If youve always taken care of it and kept on top of the maintenance, mod on with confidence. Id rather drive a car with many well cared for miles, than a car with lower, but hard and neglect ridden miles.

You would think they meant 145000, I can't imagine anyone being concerned at 14500!
