Guys, list some of your favorite modifications and why you liked them in this thread.

 

NITROUS!!! because it made me blow my headgasket which gave me an excuse to disassemble my engine and "fix" things

 

Headers and true duals because God intended for a SBC to have duals!!

 

Not if its a turbo

 

Twin Turbo's will fix that

 

LOUD exhaust.. God also intended for our cars to have the ability to make everyone think the apocalypse was coming down the road, when in reality it's just an LT1 mashin the gas a little.

 

Ya stock LT1 exhaust blows chunks. At least just weld in a cut-out. Flowtechs cost $30

 

4.10 gears, and B&M ripper shifter

 

Headers, sub frame connectors.

 

headers and cut-out, makes for one mean sounding beast

 

Long Tubes for sure. The stock manifolds are the biggest pieces of crap I have ever seen. And what a PITA to get them out OMG!!!!!!!!!!!

 

Turbo kit

 

God did not intend for a SBC to have turbos, He meant for them to breathe naturally..........unless it's a 6-71 blower!!

 

short throw shifter. long tube headers. 4.10 gears of you choose. good drop springs and shocks. bigger front sway bar.

 

Weight reduction, nothing like throwing a hole buch of pointless junk in the corner of the garage, while helping out the old track times.

 

Headers and at least a 3.42 rear gear in an auto car, 4.10 in a manual. i'd also recommend a mild cam.

 

So far the best money spent was on Sub-Frame Connectors and an LS1 brake Swap with Hawk HPS pads.

 

Yeah LS1 break swap
K&N Cai or equivalent
Long Tube Headers
Ditch The ac and the A.I.R and EGR
LT1s are meant to lope so get a damn lopey cam in there

This is what happened to me two summers agostock with cutout I ran 13.9@104
Then
224/230 112lsa and 1.6rrs
Long tube headers(jethot)
And misc things like pushrods and new timging chain
Ditched ac and emissions crap
I gained 10 MPH!!!
Thats almost 100 hp
Just make it breathe better and pollute better and youll be all good

 

nitrous.. god bless the cast iron workhorse block of our LT1's...

 

Big cam, long tubes, and probably the best 2 mods for an automatic: stall and sticky tires!
Just switching from the cc305 w/ shorty headers to cc306 w/LTs, and getting a new opti I gained 50rwhp and 50rwtq!
