Whats the best year LS1 in an Fbody??
Re: Whats the best year LS1 in an Fbody?? Best year is '02 as far as total performance and least amount of "bugs". GM always puts out the best product the year they kill it, LOL. '01 would be equal.
They have:
LS6 intake, stock. ('01 and up)
No EGR ('01 and up)
Bigger fuel tank (vs. '98s smaller one)
better exaust manifolds and cats ('00 and up)
bigger injectors like the '98s
"possibility" of getting LS6 heads like some of the '01 models got (production overrun)
2nd gear start mode for Automatics ('00 and up)
torquier cam ('01 and up)
Only bad thing about '01 and '02s are the tighter pcm regulations and increased torque management.
I like the '98s from a performance per value standpoint, but from a completely stock standpoint, the '01s and '02s are the best of the lot.

Patrick G, how can one tell if they have the LS6 heads on their 2001 car??

Re: Whats the best year LS1 in an Fbody?? Hard to tell with out removing the exhaust manifold. The exhaust port is D shaped as opposed to a regular O shape.

Re: Whats the best year LS1 in an Fbody?? '98 were made with bigger injectors and a bigger fuel pump, also a less restrictive manifold. Perfect for nitrous. But also the '01-'02 LS6 intake manifold makes a nice addition.

In 2001, GM went back to the larger injectors on the LS1s. The 98 fuel pump is higher capacity, but I am not sure what manifold you are talking about. Both the intake manifold and the exhaust manifolds are more restrictive than the 2001 + intake and the 2000 + exhaust manifolds. The double wall of the 98-99 exhaust manifolds puts a very serious restriction in the manifold and the Y-pipe is much more restricted than the 2000 + version.

Verdad Gallardo Re: Whats the best year LS1 in an Fbody?? Todd's right. The exhaust manifolds on the '00 and later F-Bodies (cast iron) are about 5 rwhp better than those on '98-99s. The smaller fuel pump on '99 and later F-bodies doesn't become an issue until you exceed 500 rwhp.

I am curious because i just ordered an 02 and it will be here in about 3 weeks. I would be the happiest guy in the world if i got some LS6 heads on it from the factory.

What type of bugs are associated with the 98's?
Can you delete the EGR on a 98 with HPP3, LS1 edit, or something similar? So the 98's show greater gains when switching to a LT header/off road y pipe than the 2000 and up cars? If you do remove the egr system from a 98 car, do you still order 98 Headers???

Re: Whats the best year LS1 in an Fbody?? Second gear start is a joke! My sister has a '97 RS V6 w/ that. In the rain, it actually causes people to lose more traction because you have to give it so much gas to get it going.

Re: Whats the best year LS1 in an Fbody?? The 98s have one major problem if you ever plan on boring the engine due to excessive miles.
The 98s were manufactured with thin wall cyl sleeves that will not except more than a .005" cyl hone (no boring machine bar). Sometime during the 99 production year, the sleeves were re-designed so as to be able to except a boreing bar up to (I believe) .020" cut
This may not present a real problem for most, but just remember; You aint going to bore the 98s.
And, like I stated; Some very early 99s have the same thin wall sleeves as all 98 (and all 97 Corvette LS1 motors).

Re: Whats the best year LS1 in an Fbody?? For me? I would have to give the nod to the 98's.
If cost wasnt an issue? 2001-2002.
The 98's had stainless steel exhaust manifolds that could be ported. Larger injectors, etc, etc.
The down sides to the 98 would be the HPP3 adjusting the shifts by MPH and not RPM. (That sucks)
The tranny programming is VERY aggresive in the 98's. In the later years the Torque magt. gets to be very intrusive. It pulls out to much timing for me. 98's tend to be able to run LOTS of timing with no problems. (IMO)
Are the 2002's coming with different (stronger) head gaskets?
Man I like the 2002's...

Re: Whats the best year LS1 in an Fbody?? I will also favor to the 98's as well for similar reason's stated above. Fuel system, cheaper on the wallet, and some of them are FREAKS.
FWIW, my 98 ran 115 traps with a completely untouched motor, unported Mac headers, stock granny gears, timing problems, and a slipping clutch. Guess they ain't so bad eh? <img src="gr_images/icons/wink.gif" border="0">
