I'm worried my stock head gaskets are going to blow. I have 101,000 miles on a EXCELLENT running car. Check my sig for more info.

Anyone here have a L98/LB9 with a blower with high miles and no head problems?

High milage itself should not hurt stock steel shim type head gaskets.
The only way you are likely to hurt a steel shim head gasket is from detonation.
The main thing to look for in a high milage car that can cause problems is oil getting into the combustion chamber. That can cause detonation and the detonation can eat parts.

126,000 on my 350tpi. No problems. so far with my paxton (crosses fingers). The first thing you need to worry about are the rings really though. Head gasket is not a big consideration.

Yo Wraith, how many times has your paxton been rebuilt? Just curious

i've only owned it since fall.. the previous owner had it rebuilt once, i don't know of the history from before that.

I have a paxton sn2000 with 8lbs of boost and mine has run fine for the past 1 1/2yrs. I put about 10K on the s/c but i hear of people having to rebuild them? I do have an oil cooler so I'm sure that will help a little. Like I said, I have had no problems with it (knock on wood!) but i would like to know what sighns to look for in a unit that is going out. Any info would be greatly appricated!!! The only reason i pruchased a paxton was because they are very quiet and i had to sneek it in the car with out my wife knowing.....wish i would have purchased an ATI!!

Man I have to get in on this. I put a Paxton SN93 unit on my show truck www.bharris.org/92GMC and changed the oil religously at 3k or less and it blewup about once a year at about 10k miles. I never pushed it above 5k rpms. I even had an oil cooler on it once until it blew up and melted down the external pump on the way to a show . Blew burn trans fluid all over the hood. As far as performance gains. You only get boost from about 2500 up. No bottom end power at all. I sold my last Paxton unit (since they covered every other one under warranty) off and I have been in the process of building my 350 5 speed to achieve the same horsepower but with a much better power curve. Just blowing off a little steam. I wouldn't have another paxton if you give it too me.
