Yeah, the throttle response is unbelievable. If I floor the throttle right off idle (initial start/roll) I can break the rear tires loose for 3-4 feet. The motor pulls hard till 6000 rpm from 700 rpm, instant power. I hardly rev the engine beyond 4000 rpm these days, but the other day I manually shifted the auto transmission and held the rpm abit higher. The engine really starts to come alive above 4000 rpm. I have 2.73 gears and still run the 700r, so 60 mph is around 1500 rpm. 80 mph is 1900 rpm. I'm running 2010 C6 Z06 wheels (fronts R18in 275 35 and rear R19 325 30). I've owned several 355HP 5.3L gen V trucks and the LQ9 seems to have more grunt/power and driveablity than the 5.3

Not sure how much more I would gain in my current engine configuration running the long tubes vs. my shorty's.

X2. That is what I would pursue.

are there any mods to the lt1 for the l98 or is that a direct bolt on? I have an all stock '85

aklim

Last time I looked at my 91,it needs some work

If you get exhaust including cat converters maybe not. IDK how well they will connect to L98 manifolds. Without converters you will need to fab pipes from manifolds to exhaust system.

something like these?

Kevova

Those would be for an LS. Chevrolet is kind of whacked about LT1 as a advertising nameplate. The LT1 was the "hot sbc" in 1970-71. Then the Gen II sbc became the LT1. The gen III LS gets an update it becomes the LT1/4.
You want to be sure they are for LT1/4 92-96 Corvette. 93-97 Camaro/Firebird and 94-96 full sized cars used different versions of the LT1. They all still were called LT1s and use different exhaust manifolds. Things would better GM wouldn't keep reusing the same 3 digits.

sb66

thanks - yeah that can be confusing - especially to a newbie like me to all of this

sb66

so more like these

Kevova

Yes

sb66

and that's a straight bolt on for $100?

aklim

Would it be worth it? IDK.

thanks - if you do not mind me asking - what headers do you have that are cheap? - inexpensive I should say

thanks

aklim

Cheap ones are those that make the best bang for your buck especially in the future where it isn't difficult to install easy to get to the plugs, good performance and long lasting. Low Purchase Price is usually none of those. LPP isn't good because it can't be. Higher Purchase Price is because it does not have to be a nor can it be.

I would like to add a point regarding an experience of mine. I bought a set Of Hedman Headers for a 1968 C3 big block with the Silver ceramic header coating, both inside and out from Jegs. The quality of the parts are great in over 25 years with them I am happy to have chosen them for my Corvette needs. The ceramic coatings look great (for a while) and they are supposed to reduce the under-hood heat.

The take home point was not meant to be the cheap headers, it was the exhaust system mentioned in the 1st post. You asked about the dual kit. I have it and it bolts right up to your stock exhaust manifolds, perfect fit. If you're staying near stock i recommend it. Regarding headers, I have hedman 68440 un-coated headers that i sand blasted & ceramic painted and cured in my garage. I have
a T56 6 speed and aftermarket heads. I had fitment issues, to state it mildly. "Hammer to fit and paint to match" was the motto building it. They are 7 years old & beginning to show their age. My next set will be good ones.

If you are not installing long tube headers, don't waste your time or money. Most headers I have seen will always need a little bending to get them into place on a L-98. IMO long tube headers and a free flowing exhaust is one of the best upgrades you can do to a stock L-98. If done with good matching parts you will feel the difference.
Just my experience.

aklim

Totally concur. Either pay more now and have something that will perform in the years to come or pay less now and get little to nothing.

I'd save up for good stuff that lasts instead of the mental instant gratification and wallet regret in the future. BTDT and don't want to do it again.

ctmccloskey

I concur as well, tried both the long tube header and the shorty style and the long tube design is far better for making power.

On my Hedman Headers, I never picked up a hammer or had ANY fitment issues. They bolted right on, and fit around my clutch assembly, a sign of quality company who does their homework.

Long tube headers do cost more but they are worth more to your car's performance capability! I would also get the Ceramic coating put on at the factory, after a couple years I saw spots developing on my headers and Hedman replaced the entire system just to keep them "looking" good. They could have had mine re-coated but they gave me a whole new set just to keep people happy, I like companies like Hedman!

Don't save money on headers buy the long tube design and you will never regret it.
