well you can buy close-deck sleeves from darton for about 450 and have a maching shop put them in for about 500-800 depending on where you go....

400whp is the "average" around 20-24psi is where they tend to fail.
CJ had a car that ran 350whp for 3 years, one week at 400whp an it busted a sleeve.
Most people will be ok around 350-375whp if they take care of the car. 400whp and one wrong move an its game over.
