it killed over today… it was spinning one tire alot harder than the other one for alittle while and i knew it was wearing out…but i didnt think i’d break it like i did.
i went 1.79 60 foot…on way to 14.0 at 94… knew something wasnt right and when i started to turn, i soon found out. the rear is all banging and cracking on the turns, making hella noise. its shot… oh well
so not only is the rear broke but it seems like i have other issues since my times and traps are down .4 tenths et and 5mph…something aint right and i thought so since the car didnt feel as strong on the street as it did before the gasket swap and torque arm… but maybe the rear damage slowed me down…idk, oh well i got some work to do. lol
sorry to hear that, time for a new car
lol naw…i’m not gettin rid of this thing yet…
on craigslist today theres a guy partin out a 87 iroc and a 91 bird. email him, ofcourse he doesn’t have the damn motor :mad:

i got Ls1 rear off of brian a while back…just was waiting to put it in as i thought mine was goin bad. finally broke it
hey man, for a 383 build I’m plannin on puttin in a third gen, do you think I should go carb for the HP or an aftermarket TPI for the torque? You think a TPI would choke a 383 even with AS&M runners and a TPIS mani base?
most hot 383 tpi setups make INSANE torque…i’m talkin upwards of 450-500wtq or more. you’d want a strong rear end for that. but they only make around 300-350whp. superam setups are nicer and give more hp with some sacrifices in torque. but they are expensive and PITA to work on. i seen these setups make near 400whp on the right combo.
other bet is miniram or LT1 intake. that will give you just as much hp as a carb setup. and a nice flat torque curve. these intakes are good for 400-500whp with a big cam and nice heads. 87 TA on this site has a 406 miniram…probly near 500whp.
but dealin with the ecm and tuning those computers kinda sucks. carb would be easier i think if you have experience with carbs. alot of ppl do so they could help you out. other option is to run some kind of aftermarket DFI setup like FAST, Accel, Holley commander 950 or something. some tunners in the area probly could work with accel dfi stuff.
depends on how fast you wanna go. TPI torque on the street with a converter is hard to hook on. but you wont have any topend power…motor will be dead at 4500rpms. at the track its a rush to launch that hard but you have nothing else after it. TPI cars launch like 12 second cars but only run 13’s
I was wonderin about the trouble with tuning the fuel injected setups. That’s one part I haven’t looked much into yet, hence why I was thinking about just using a carb. I’m thinking a carb setup would probably be cheaper too. If I was gonna skip the tpi shit I’d probably just save to run a stealthram, those things make some nice power but a whole topend is like 3 grand. Staying tpi would cost maybe 1200 for aftermarket tb, plenum, runners and base. I have no idea how much it would cost to burn a ecm or prom or whatever those motors use. I really wanted to stay away from superram and LT1 intakes
and I wasn’t even thinking about ET yet, I really just want a fun street car that might see the track a few times. maybe 350-400hp would be good
oh yeah, and that’s another thing I forgot about…no fuckin way would I be able to hook up a 383 tpi on the street lol. Maybe I should just look into a carb setup
the closest shop that i know that can tune these cars on the dyno is LSracing chips in ohio. they have mail order chips too. anywhere from 300-400 bucks i think for the dyno tune. not sure on the mail order but they could probly make a nice chip. i have heard good things about those guys
you can snag good aftermarket TPI stuff for less than 1200 if you shop around and use ebay/classifieds. i got a like new accel superam tpi base for 250shipped. later ported it out and sold it for 300 on ebay. they are 450 brand new or so. runners, the only ones worth buyin are as&m and TPIS bigtubes… for a 383 i’d go siamesed which are like 475 bucks. so kinda pricey.
that will make 350whp tho with good heads… good heads are a key. i see alot of guys running afr 195s. i’m curious as to how the 180 would work with TPI and 383. smaller runner equals more velocity and usually makes better low end power/tq. but probly dont need anymore low end and should go with a head with 190-200cc runners but its gotta flow pretty good.
stealth ram could be run with TPI computers. you dont need the whole top end kit, which goes for about 2300 by the way. thats a good deal considering what u get with the kit tho.
tuning isnt all that expensive if you burn your own. chips are a few buck a pop, and the adapter to plug them in is 50 bucks. you can get a chip burning kit complete for 300-350 bucks or so, which includes software, burner, etc. i’m just about to get into that game, and with help from 87 TA, i’ll be on my way.
you think carb would be cheaper than any EFI? I’m searching thiedgen.org right now to see what people are using and puttin down. I’m friggin torn between carb or tpi. the tpi torque might be too much to be usable.
I’ve seen some homegrow siamesed jobs on aftermarket runners that looked pretty good, doubt I’d pay for some if I could do it myself with a die grinder.
I’ve still got lots of time though, the bottom won’t be done before spring
could be…cuz the carb manifold is cheaper than full TPI setup. 200 for a mani, and then the price of the carb is what? 400 bucks? so the price will probly be cheaper than TPI as tpi is around 700 for aftermarket setup…then add 300 for the TB that will be needed for that 383.
what sucks is that you would have to spend lots of time tuning the car with TPI/ecm. it may take awhile before u get it all together and running like a champ
i’d talk to 87 TA (tom) about it, and he might beable to help you out with a tune to get u close. he did a great job on that 406.
a 383 carb motor will still make tons of bottom end. combine that with the right gear ratio and a converter if you go auto, and you’ll love it!
at the strip on et streets, i doubt you’ll have excess unusable torque from a TPI car. it should hook fine with suspension mods. you’ll cut great 60 foots. that much torque off the line is a rush at the track. u just will die off at the top rpms.
i’d rather have a intake setup that will pull to 5500 like holley or superam/miniram…or carb manifold
yeah I keep reading and if this car won’t be a daily driver(it won’t be) carb is WAY cheaper and easier to tune than EFI. Only thing, carbs lag off idle and mpg sucks balls. That’s all I could find for cons, though. They make great power.
I also hear that a 383 generally makes peak power at 5500, that’s way after the TPI falls off, which will, in a sense, starve the motor. I’m starting to think tpi isn’t worth the trouble with the extra cubes.
thats about right… new modern carbs are pretty good. if you go carb get a good one and work on that tune… theres no reason you shouldnt be gettin upper 1-teens mpg with that motor.
and yes TPI is not great match for 383+ motors. thats why i’d look at stealth ram with TPI ecm/wiring harness and tune that if i were goin EFI.
yeah, thanks for your help man
I’m sure you didn’t quite expect a flood of questions about fucking gen 1 motor setups. Good luck with your ls1 rear
/highjack
haha no problem, i love talkin about gen I motors as everything nowadays is LS1 this, ls1 that lol
glad to be of some help…hit me up with any other questions… i been on thirdgen for awhile and i could probly get the info you need
