3.4 engine switched pushrod

would the engine run smooth and idle ok with a switched pushrod. I mean exhaust with an intake. My car idles great but has hesitation and low power when taking off.

you're a brave soul to even think about writing that. if your impala found out what you're writing about it would probably never start up again. have you read some of these threads that people posted. these new body impala's make yugo look like a sturdy car. goodluck whatever you decide.

What!?

didn't switch pushrod. The cat was blocked replaced it with a hi-pro and it runs like a raped ape!
