Blew the engine (spun bearing) in my 99 T/A...was running a 7.9 1/8 mile with a 3600 stall/ 224-230 cam/headers/342's/drag radials.

MY goal is to run high 6's in the 1/8th mile on motor alone. but also be able to spray is little bit, nothing huge, and really fly.

I am not against iron blocks or strokers! im just looking for bang for the buck!
what ya all got, or know that works?

Money? keep it under 5-6k

6.0 truck motor /w 317 heads so after 2000 if you wnt to go really cheap swap the old intake on the truck motor and maybe even the cam if it isn't damaged. Swap the water pump and pulley and oil pan. Get brackets for accessories. Put in new pushrods, gasket, and arp head bolts and you're looking at $1500-2000

I wouldn't be posting in new ls1tech users to ask how to run 6s first of all.

Under 5-6k is not going to get you a good 408. I would look into maximizing a 6.0 or 346. I would personally go 346 for the added weight savings. The 6.0 isn't going to make that much more power.

If it were me..
Afr 215 heads
a cam suited for your setup.. Probably something along the lines of 232/234 .600 112 Talk to Pat G or Pred Z, either will get you squared away.
FAST 102/92
3600-4000 converter... Really to maximize your setup on motor you need a 4000-4400 converter. But most converters that size won't like a decent size nitrous hit on it (100+). I personally would call PTC and see what they would recommend, *amazing converters at a good price.
410s or 373s... This all depends on how much you drive the car on the street/HWY as well as what size tire you are running.
Underdrive pulley
Chrs1313 ram air
LTs with a good flowing exhaust (cutout) or more preferably Xpipe, will cut some weight and flow just as good. And sound WAAAAAY better!
Suspension... LCA/panhard/TQ arm/shocks
Tune
That should get you there as long as you are running at a good hooking track and average DA.

ummmm...406-427 short blocks are only 3500... Lemons i dont know where your getting your info and its is rare to see an LS1 engine without N2o run a high 6 on motor

i would suggest you take your valve stem caps off, all that rotational mass will kill you

Ok, have fun. Just remember, you were the one asking how to run X.XX times, not me.

Let me know when you get there and I will let you know when I get there. I'll probably talk to you in about 2 weeks.

Also, let me know when you put together a 408 long block (a decent one not some half *** budget setup, you can run as fast as a tight budget 408 with a well built 346, ask me how I know) for under 5K, I want to order one from where you got yours. It is rare to see a non drag car 346 run 6s because people don't pay attention to what works and doesn't work and do their research. You do that and you are guaranteed 6s (granted DA isn't outrageous) if you will spend a few thousand bucks on H/C/I/E/Susp. A car works when it is built right.

Hope you hit your goal.

If i say with the 346 i was going to do fly cut pistons/Trex/Dart head possibly/LS6 intake, but i just dont have much faith with it hitting that goal or being very reliable...but i dont know. I already have the suspension things you mentioned(other than the panhard) and the headers/cutout/etc. Im looking for engine only at the moment...even though about a 370, or a 383...just dont know. there are so many different options and people getting different results with the exact same setups. no replacement for....you know the rest

I have a full weight car..226 .588 114 cam 373 4k ptc hand ported 317s ls6 intake nitrous tune suspension underwrite pulley.. I ran 7.3 @ 93 last trip to the track barely spinning with a 1.52 short time.. that was in 80 degree weather, da was around 2200+.

I went to a ported 102/92 setup.. changing to x pipe with 1 chambers and a retune. That wih a bit cooler weather should net me 6.9-7.0 at around 96.. I can still major upgrade heads and get another cam to beter suit he new mods. Again, i have zero weight reduction.

I have a stock 376 6.2L with a Tsp 229/236 on 112 cam and milled Ls3 heads, 1 7/8s headers with a FTI 3800 stall and 3.42 gears. Runs 7.0s at 104mph on 16/17 inch tires with only 1.7ish 60ft's. Since i have dropped 75 pounds and added a FTP 104mm lid and ram air. I drive it to the track and home. Runs 6.40's at 113mph on a 150 hit.

If i can get a 60ft to match tomorrow ill be happy with this $450 longblock! lol

with enough weight reduction, suspension, drivetrain, tires, proper head/cam package you can get into the high 6s with a stock bottom end LS1.

Oh, yeah, i know that is possible but i forgot to mention i want to be able to drive this thing on a road trip if i wanted and keep almost all of the interior. I will however look into the whole tubular K setup

I think you could build a decent 408 with that budget. Find a 6.0 truck motor with 317 heads. Swap your current cam (assuming it is still good) and accessories, and get a fast 102 or victor jr setup. I would upgrade your stall to 4200-4400. If you can hook, you should be looking at high 6's.

With the new block, rotating assembly, intake and machine work you should still be within your budget

Awesome man, if you do let me know im interested!

Do you read?
No weight reduction needed.. no tubular k member needed.. no donkey dick cam needed. Not even close to any of that. The first fbody in the ten years and years ago had a mid 220 cam and weighed around 3300# iirc.
If you will be fine with a solid 6.9 car you are way over shooting for your goal.

I think if you got a lq9 and a ls6 intake ,and a Patrick-G cam you could easily run 6.XX 1/8 mile.use all the brackets and pulleys off your ls1.you should get some good suspension pieces and better gears. your will probably need a better rear end.maybe mill the heads and do a good valve job,and install good springs.use the stock rockers ,but get good push rods.
