ugh... after 6 months of going back and forth between boosted, na, nos, 454 lsx's, 427's, 408 ls1's, and lots of other combo's.... i still dont know what the heck to do! here is what im thinking.... using ls1 block, as i really dont want to buy another. id love to hit a 9 sec quarter time! im okay with 10's. so you all can get a good idea, car is a weekend street/strip car, i will have complete suspension on the car, moser 9", t56, upgraded fuel system, open header exhaust, 315's in the rear and race weight will be about 3800 roughly..

questions: how big of a stroker kit can i put in an ls1 block without having to worry with clearence or boring out? and is it possible to hit 600 hp going NA with an LS1? i am looking for rotating assembly, intake, cam, head, TB, ect. set up suggestions. general at first, and more detail as i figure out which route to take. options must be NA, and include ls1 block. i would like to be cost effective. but want more than slapping on 706 5.3 heads and a cam. i appreciate any help!

 

i can tell you right now, with a 6 speed, and 3800lbs, you are most likely not gonna run 9's.

if you are gonna do stroker kit (and dont plan on doing the work yourself) then you might as well call up TSP, do a GEN III Iron block and go 408. you can get the whole bottom end out the door for just about 3K! and good thing about the iron GEN III is that all your LS1 stuff will slap right on there!

now that combo will get you in the 9's, even will some ported LS1 heads.

 

you must be talking about their 408 kit and that 6.0 lsx iron block thats only $800 (talking just the block lol) i wondered about that assumed it was just an LQ4 essentially. not going to rule that out prolly be just as much to have my old block polished. so what are some good flowing heads that wont kill my wallet for the 408's?

 

i dont think your going to be able to stroke that ls1 and hit 9's. only cars running 9's that ive personally seen are either spraying on forged motors (ls1's and any other ls motor that you can get to fit) or supercharge/twin turbo. and a few with spray and turbo. if you want a mostly motor setup build a strong ls motor and spray the hell out of it

 

Lolololol

There are stock bottom stock cube cars in the 9s. Boosted stock bottom 5.3s in the 8s.

408 with a 200 hit on it... M6 is going to be hard to hit 9s.

 

Im fine with 10's. Just saying 9's would b nice, didnt really know how realistic that goal was. Its not exactly the time im so much worried about its having a motor with the sufficient power to get me there. I probably wont race much, i baby this car. I just want a 9-10 second setup with a good powerband, ppl always talk about dyno numbers and peak power, but that really dont mean jack squat if your power band has a hard slope to it.

 

like i said only ones ive personally seen are not stock bottem end. if youve seen it then yay for you

 

Texas Speed did it at LSX shootout.... Twice. With 2 different combos that is. Video on youtube. Ran 9.82 and 9.66 but the race weigh was 2800 lbs. So i get the feeling with my extra 1000 lbs, my lard *** will not see single digits that way. Which is why i came to you all. Sponsors feel free to chime in here, you probably know capable setups better than any1.

 

hence why in your case i said your probably not going to hit those times with stock bottem end. and honestly, would you want to be running that high horse on a stock bottem end? i wouldnt. id like not not at least worry about if my stock bottem end is going to give out on each pass

 

Im not making arguement for either side, bc i dont know. Im asking those who do to tell me how to get there, or close.

 

ok for a second i thought u wanted to build it all on a stock end thats why i threw my 2 cents in about it. for instance i was about to do a procharger build with afr heads and a medium cam but i yanked the build cuz i knew my bottem end wouldnt hold the hp for very long. good luck with your build i know i change my mind on how im gonna build my car every 2 days

 

Decent heads
Mid size custom cam
Built rear
Supporting bolt ons
Etc
Hit it with a 150 hit
Conservative tune it should last forever and should easily hit 10s.

 

10's is definitly doable, even with moderate heads/cam, all the bolt ons, a good tune and a 6 speed. but now when hitting 10's with a 6 speed, it is not just all about power, you have to fight with clutch slip, launch, shifting, rpm chasing, gas pedal fluctuation, and drive line breakage. the 6 speed in our cars is known to kill clutches and rear ends like it is a sport. you also will need proper drag set up for a good launch on a clutch, which will not be the most ideal for a street setup. now i have seen it personally done with just over 450rwhp, and stock rear springs with some LCA relocation brackets, a 9" and 4.10 gears. but this guy was a VERY GOOD DRIVER! so get your driving mod up and you will be much closer to the goal of 10's!

but in my personal opinion, i would get the TSP 408, cause everything is new, all the LS1 stuff works on it, and i would get some TEA LS3/L92 Ported heads with the hollow intake valves (or LS2 heads if you already have a FAST setup like it do, and dont feel like forkin out the money for a 102!) the ported heads with LS3 valves can be had for just under 1200! (if you supply your own cores that is)

btw if you do go 408 from that, i would get all Calies internals with Wesco pistons. it is the best setup for the money. then i would talk to pat G and tell him what heads you are interested in, your track wants, and he will give you some cam specs that will BLOW YOUR MIND!

 

can you bore an ls2 to match the ls3s bore?

 

Gave me some options to think about. Thanks. And I was told that callies kits have clearance issues... Here's what I was thinking roughly... If there is a hindering part, lmk. If there's one that is over the top... Do the same.

6.0 iron block
408 kit from TSP
MS3 cam
227cc AFR heads
96mm FAST typhoon intake
92mm big mouth Throttlebody
100mm MAF

 

if you are gonna spend the money on a good intake, go to vengence and get a ported 102, ditch the typhoon intake

for a cam, go bigger or you will be dissapointed, do like a 239/251 LSR cam or the MS4

also you will need the 104mm lid to effectivly run the 100mm maf. also see if you can get a ram air kit or the lower WS6 airbox

 

that SAM car hit 9s many yrs ago on a stock short block and from what i remember it was NA.


it i really wanted to run 9s id be running big cubes with a big shot with an auto.

 

Would the FAST 102 be about the same? If I'm going with the 102, I figure I'll upgrade the throttle body to match also.

With the cam I like a big choppy lope, and may just end up going with a custom grind to better suit what I've got and what I want. I realize I'll have to replace my lid. I do have the ws6 high rise platform. And ram air kit on the car now.

 

I am also interested in peoples opinion on this subject. Subscribed

 

For me the biggest cubes that I could afford and TFS 235's that put down a ton of bottom end torque. Love the car. Now forth gear pulls like third gear use to when it was H/C.
The cars numbers were with a 90/90 through a 85 mm maf and the stock over the axle pipe.
