[l3lomi]

Ok so I have a 99 camaro as with a 5.7ls1 and about a month ago I went through some flood water and messed it up so a friend of mine is saying I probably just need to suck the water out of the cylinders and ill be alright so I'm gonna try that tomorrow but I'm case that doesn't work any suggestions or even if you guys could tell me about some engine rebuild shops that are good and keep in mind I'm a 22 year old college student I can't afford a 10000 engine rebuild I'm in Houston Texas so any info will help thanks guys
