So I recently got a 94 z28. the guy I bought the car did the following this is what he emailed me. crate lt1 engine by ATK,,WITH a lt4 Intake ,TBand lt1 injectors ,Headman full length race headers welded all the way back threw to 1 twin chamber flowmaster than ends with a chambered chromed tip also have 4:10 gears but what I want to know is what is the estimated Horse power you guys think this car has. this is my first chevy so I don't know to much about the car. just trying to get a little info.

also has a cold air intake.

 

I would say 270-300 wheel.

 

Same, however I doubt it has a lt4 intake since it will only bolt up to lt4 heads .. People think they paint them red and magically they are lt4..

 

cool thanks i just have 1 last question, if its not too much. but the car is dual exhaust but only has 1 exit pipe, is the hp a big difference if i added another exit pipe to have two pipes coming out the back instead of 1 or its not that big a deal?

 

Not an issue.

 

I know it would be louder

 

There really isn't anything power adders on the car besides headers I would say what someone else said 270 to 300

 

Basic CAI/header/exhaust cars put down anywhere from 250-270whp with M6 cars averaging slightly higher.

 

What is m6 cars? Im also looking to see what else I can upgrade that isn't any serious work. But I can't think of anything looks like the headers aren't factory buy I will post pic when I get home

 

Do you have an automatic or six speed? M6-T56 manual.

Back when I had 1.6 rr, BBK shorty headers, K&N CAI, 10 bolt with 4.10 gears, the car put down 300rwhp/318tq. M6.
