here's mine...

------------------
86 SC, 305 LG4, TH700R4, SLP headers, 3" cat and exhaust. Mild cam 204/214, .423/.442. SLP shift kit, richmond 3.73's w/limited slip. Susension Technique Sway Bars, Globel West Wonderbar, Poly everything bushings, Metco LCA's, Lakewood Panhad Rod. 16" ROH, with Toyo 245's. For autocross, 16" IROC's w/bfg R1's... Need more speed.....

 

My mods are in my signature. I'm still using the orginal block and pistons from my LG4 that have about 100K miles on them. The heads are orginal too but have had a lot of work done to them. I've had a best 1/4 mile run of 13.4 at 101mph so far. So an LG4 can run decent times if you match your combination up well.

------------------
84 Camaro 305 ported & milled heads, 3 angle valve job, Edelbrock Performer RPM intake, Hedman full length headers, Accell ignition, Crane 274H cam, B&M 700R-4, 3000 stall speed, 4.10 gear,

Current Plans: 342 posi disk 10 bolt rear, coming in late december, in february or april, level 10 tranny, new convertor, june- lowering springs, possibly torq thrust II chrome wheels, and new 245 stickies up front, 255's out back, the cowl hood will be installed and painted, new cold air induction, mid summer, hoping to have enough money to scrape together a 350 hp 350... gonna keep things fairly mild.

My Webpage- Battle of the birds, My own Thirdgen Page, still under construction, http://www.geocities.com/soares711/index.htm

88 Firebird Formula- deseased 2/9/99- 305 TPI, SLP 3 inch exhaust, SLP Intake runners, SLP cam, 3.45 BW disc brake posi, WS6, NOS, and all that good stuff, 13.8 on the motor, 12.89 on NOS and slicks! Hit by what else!?!? a FORD EXPLORER!!!!!!

 

fb305svs, how did your carb spacer work out? have enough underhood clearance? ive yet to start work on my lg4 iroc, but once i do my first mods are gonna be a slightly bigger carb and spacer, but was worried about clearance..

aside from that mods to be done
head job, cam, performer intake, carb, cooler stat, catback kit, etc.. i dont know about headers yet.. possibly, yet doubtfully..

 

Mine are in the sig, oh wait, I guess I don't count any more. Hey, its still the LG4 block, heads, and exhaust manifolds!!!

This was the best mod I have done to my LG4!!

Nothing very exciting, but parts are waiting for warm weather and dry roads. (intake, exhaust, MSD)

------------------
'86 IROC-Z, 305 LG-4, T-5, T-Tops, 50k Original Miles, K&N Air Filter, Jet chip, KYB Shocks/Struts, Centerforce Dual Friction, B&M Ripper Shifter

 

Getting rid of that stupid clutch fan made a difference off the line (Dual electric). Regular maintanence has been a big factor, but more in the fact that it's still running at 199,500 miles. Timing reset to about 10 degrees.

The best mod that I will be doing to it in the future, is replacing it with my 350 (basically a ZZ430).

That looks sweet in there GMTECH. Nice airbox!

Good luck with whatever you do!

The best mod for the slacking lg4 is to replace it with some more cubes like I did mine with a 383 stroker 330+hp 440+lbs-torque

 

I been needing to try on my FlameSuit on again it's been a while. Dual snorkel intake, headers, performer intake reworked Q-jet and gears should get you low 15's high 14's at around 90-93mph if your engine is in good shape. A performer cam would lower that by half a second at least and add 3-5mph trap speed. 204-214.

 

K&N open air 14" element, double roller timing chain, no smog pump, carb tuning, shift kit, no cat, lead foot.

------------------
'82 Firebird, dead stock, 9 bolt disc rear, over 200,000 miles and still going strong, more to come...

 

i used to have an LG4. I had a 14" K&N filter, Holley 650 carb, 1" spacer, edelbrock performer intake, plugs and wires, as well as a valve job, i also removed the A/C and the air pump, no cat. I'll tell you one thing though, the holley 650 had some great throttle response. it never bogged and always wanted to go. I reccomend the smaller carb actually. Just from personal experience.

------------------
If it breaks, it wasn't good enough anyway.

 

removed lg4... installed L69... slp catback... installed 700r4... much more fun...
