I need some feedback please. I am thinking about buying the Kooks 1 3/4 x 1 7/8 x 3" LT1 headers for my 93 Z-28. Will I be able to use my new LT4 starter and can I still use the factory oil press sender at the 93 position just above the oil filter on the block? Any help would be great. Thanks.

 

What mode do you have done? Those are awfully huge primaries for very high horsepower applications.

 

Thanks for your reply Kwik Ta. I have enough motor to use the stepped if I was racing. I am going to the straight Kooks 1 3/4 " x 3" header since this is a street touring car. Average Hp and tq will be better with the straight header and duel cat Kooks Y pipe to a Corsa catback slightly doctored on intermedate pipe. Still interested in hearing if my LT4 starter will work on straight Kooks header tube? Any info would be great.
