iv got a 1984 camaro that im going to put a 604 crate motor in it has d port heads, with a kick out oil pan, what headers would be my best choice? i would like to use long tubes 1 3/4 max. or 1 5/8 min.my car is not lowered. im going to keep the AC,power steering, alternator. the car is for the street and maybe a couple of times at the drag strip

 

How much are you wanting to spend? Though I'm not sure if big block headers for a Thirdgen are still available, the port spacing between big blocks and LS is said to be very close. You may look I to the cost of long tube 1.75 LS headers and just have a shop modify them.

 

its a small block. i dont want to spend more than 900. i want to go a with a daul exhaust system

 

Wouldn't a 604 be a big block?

 

No it's a small block the 604 is the last the numbers is the casting number the 604 is a racing motor

 

Some parts from the zz4 will fit the 604

 

Best fitting for small block would be the hooker long tubes. The fit is fantastic but they aren't great for lowered cars
