i finally got my stuff back from the machine shop today after a little over 5 weeks of waiting.

i will be putting it together and installing it over the course of the next 3 days.

the build consists of

stock crack(turned)
stock rods
speed pro flat tops
gm vortec heads with alex parts springs
lunati 60103 flat tappet cam
jegs 331 champion vortec intake
magnum 1.52 self aligning rockers
edelbrock 750cfm carb

thats pretty much it for the motor, the rest is in the signature. i will be using the stock serpentine and not using the smog or a/c
the build sounds pretty basic but im hoping for 400hp to the crank.

i am a broke college kid and i just found out i got a summer job with my dad so the next and only item i will buy for a long while is a yank 4k stall converter.

my goal is a 11.99 1/4 mile when its all said and done.
i only plan on spraying 100 to 125 shot max and i want the 11.99 w/o nos

ill be sure to take pics of the build and install.
let me know what you all think

You need a better intake. Your cam goes to 6200 RPMs, the intake only 5500.

You should get a real carb.

If you run 11.99 NA, you'll run low-11's/high-10's with a hundred shot, meaning you'll need a 6-point roll bar. A broke college kid should probably stay away from laughing gas.

carb is still in the box and free from my dad

the car will see 95% street/5%strip, so until i save get some money for an air gap or something along those lines its all i have to work with.

cheater kit was also given to me, i used to run it on my old 355, it was jetted for 180hp. although, it needed it to get it moving with 2.73s and sadly my local track doesnt have a tech inspection to pass. dad runs a 9.XX w/o a cage.

thanks for the input, and i will address these issues asap. i know i should probably get a holley lol

oh and ill be tuning with a wideband so hopefully i can get the edelbrock figured out

355sleeper

iTrader: (4)

ok so i got a little bit done, plastigauged the crank, its all in spec, got the crank torqued down. and i got all the rings on the pistons and the number 2 piston installed. should be getting around to the rest of them tonight and the oil pump installed

355sleeper

iTrader: (4)

got all the pistons in, the heads on, cam and timing set on, lifters, pushrods and rockers. all valves adjusted and intake manifold and valve covers on.

stuff i have to pick up at parts store- timing cover, thermostat and oil pump pickup, and oil pump bolts.

my goal is to have it in the car tomorrow and finish the exhaust and take it for its maiden voyage on sunday

355sleeper

iTrader: (4)

ok so now i have everything on but the front acc. putting those on and dropping it in. hopefully i will get the cam broke in tonight.

as soon as i find my computer cord for my phone i will post all the pics ive taken(close to 20 i bet)

Gonzales0501

Keep me posted on the time you run please. I'm doing a 385 build with 4:10s with a built tranny with a 2700 stall and i'm hoping for those same numbers but with no spray.

355sleeper

iTrader: (4)

ok got kinda pissed after i went to prime it, i forgot to put the oil pump drive on. pulled the pan and have that back on and the oil is in it now(along with break in addititive). waiting until tomorrow morning to prime it. aside from that its 100% ready to drop in.

and it will be another month or 2 before i make it to the drag. i wont go until i have the 4k converter and some rear suspension parts and some drag radials. so 2 months max

redneckjoe

looking forward to some pics.

355sleeper

iTrader: (4)

getting ready to prime it and look for leaks. then its ready to drop in. hopefully i have a stock type starter laying around coming from an offset starter. if not it will be another parts store run.

355sleeper

iTrader: (4)

i stayed up working on it until i couldnt work anymore. the motor is in, headers on, radiator and all my hoses. the majority of my time went to fabbing up the rest of the exhaust, it is 2.5s into a single 3.5. i have it close but needs tweaked just a tad for the best ground clearance

355sleeper

iTrader: (4)

got the exhaust finished and bolted on, distributor in, plugs, wires, carb, nitrous plate/selenoids/purge and a bunch of odds and ends, only a couple minute things to finish up and get it fired up.

i didnt reach my 3 day deadline but i wasnt counting on a whole day for exhaust(ran out of argon)

redneckjoe

man take your time 355. lol. sounds like your really jamming it out. are you t.i.g. welding the exhaust? been following your thread cause it seems a little similar to mine. i think your on track for a hot street ride. what did you end up doing on your flexplate/starter issue? there are flexplates drilled for 2 different size converters, but i think its the 168 tooth? id junk the 400 flexplate as advised before. photobucket has been working for me, i send pics right from the phone, copy/paste the IMG code. no cords needed. best of luck, and keep us updated. joe

355sleeper

iTrader: (4)

nope im mig welding, the stuff im using is ur typical 16 gauge, so im welding really low volts and i seem to be getting awesome penetration(some dont look the best but no one will see it lol

oh forgot, i used a 153 and a straight starter

355sleeper

iTrader: (4)

first pic is old 406 that the 355 is replacing

355sleeper

iTrader: (4)

just a pic of the car, get more tomorrow

1986Z28OWNER

iTrader: (1)

So you took out an aluminum headed 406 and replaced it with a cast iron head 355??? No offense but that seems like a step backwards.

355sleeper

iTrader: (4)

no offense taken, i bought the car knowing i would not get to keep the motor, so from my standpoint, the 355 will be plenty. it only has 9.4 compression pistons so i would imagine even with iron heads it will be very pump gas friendly

355sleeper

iTrader: (4)

im not going to lie, im getting pretty burnt out.

its down to the final couple things, like fuel line, wiring, and the rest of the fluids. hope to get it started in a little bit though. then the feeling of being burnt out will hopefully be over

355sleeper

iTrader: (4)

so it is done finally, all of my perserverance has paid off. i did not get to start it though, forgot to put the plugs in the head and only had one, i have the plug now so thats all she wrote. ill put up a couple more photos of the exhaust ground clearance and the "almost" wired engine bay.

i have about 5 to 6 inches of ground clearance with the stock 700r4 crossmember. the suspension is 100% stock aside from air shocks on the rear.

redneckjoe

shes coming together! break your cam in right, tune it, and work out the bugs little by little. rome wasnt built in a day. nothing like doing it yourself!

TheMonster

Damn man, you put that motor together fast! Sounds like a good build, My 882 heads should be at my house in a day or two, I snapped the back pin in stud twice, on two different heads. Got some guideplates, hardened pushrods, and screw in studs. Can't wait to start it up!

355sleeper

iTrader: (4)

thanks guys

i am using 20w50 valvoline vr1 oil and comp cams break in additive. plus i smeared that cam pretty good with the lunati cam lube. i am using a aem wideband so hopefully tuning will be a breeze. ill post a video of it running.

thanks again for all the kind words and support,
justin

TheMonster

I'm thinking about using synthetic oil after break in, but not sure yet. I used some summit zddp oil for my cam with straight 30 valvoline

355sleeper

iTrader: (4)

im not going to make the switch, i am going to stick with vr1 oil and continue to use the comp additive

synthetic is overrated, my neighbor changed his oil 5 times the whole time he owned his truck(bought it new) he put 225k miles on it before it started to knock.

92firebird 305

i have a 350 bord 30 over with stock tbi heads that have new valve springs rated to 550 lift and port and plish its got trw 30 over flat top pistons also a scat crank im gonna put a lt1 cam in there im just wondering if ill get well over 300 hp right now i have a 305 tbi that dynos 202 hp and 268 tq to the rear wheels i have not done anything to the 305 tbi engine wise just other stuff i just want my 350 to have some good power numbers i think it has the pink rods from what the guy at the machine shop said i should be right about 385 hp im keeping tbi to gonna get a bored out tbi with 350 injectors and a chip or i might go ebl what do yall think ? Should i get a better cam

redneckjoe

the vr1 racing oil still has the zddp in it. its all i ever run. some guys swear by the rottela oil also, but i just use whats been working so far. idk about the synthetics, ive heard a few people talk about getting seal leaks from useing it. not sure there is any truth to that or not?

TheMonster

At walmart they have truck oil, rottela like you said, that has zinc still in it, and they have synthetic with zinc. Seal leaks may happen because it can clean out the gunk that has been blocking the leaks from what I've heard. If you have good seals on your gasket, like you would with regular oil anyway, I don't think there will be a problem.

iTrader: (14)

Sorry, I can't let that kind of stuff go unchallenged.

I will agree that the hydrocracked Group III "synthetics" are over-rated. But don't paint with too broad of a brush.

If your neighbor had used a Group IV PAO synthetic, it wouldn't have started to knock.

If you respect your engine, you'll give it what it needs to live.

This is a great flat tappet PAO synthetic:

oh i agree five7, my neighbor doesnt care for his vehicles, and if he would have the truck would still be around.

anyways, i got the cam broke in, had to shut it off once, got to 230 and only got through the 20 min at 2k rpms.

the cam idles very well, i have my idle set at 850 and its very quiet with the magnaflow, the cam isnt noticeable unless you are behind the car and hear it through the exhaust.

timing is 13 degrees initial and 34 all in

355sleeper

iTrader: (4)

i tried to read that a couple times and am having difficulties.

from the sounds of it you are keeping the stock heads and are getting an lt1 cam, and aside from that you want to uprgrade your tbi? and get almost 400hp. the goal is possible out of a 355, but with the setup you have it wont come close.

do you have a roller block or have to get retrofit lifters?
whats your compression?
whats the actual flow on the ported heads?
what about intake manifold?
do you have full exhaust?
there are many variables aside from what you listed,

and look into the lt4 cam if you are set on a roller

redneckjoe

it sounds really good Justin! did you break the cam in idleing? sometimes a fan helps in front of the car. so hows she running? hope your haveing some tire shredding fun soon!

355sleeper

iTrader: (4)

thanks a lot man, it was my first sbc motor build.

no that was the first little bit running, just enough to set the timing, i broke it in like lunati's cam card said

it just has the stock single fan that i haved wired to run all the time and a 180 stat. im also using a summit brand high flow water pump. I think i will be switching to a black magic extreme fan though and an aluminum radiator to take care of the idle heat.

i have yet to drive the car yet be cant wait to, i ordered a one wire alternator from summit today, my harness was cut for one previously. almost 200 for one lol

ill keep you posted on how it drives and pulls. and i love how quiet it is at idle, and it has that nice magnaflow sound when you rev it. cant wait to run it!!!

redneckjoe

it might just seem like its running hot if you were sitting there in park, breaking the cam in? hopefully when your moving you wont have any issues.
that sucks about the wireing problems.
i like that your exhaust doesnt sound stupid loud.
again, great job bro! especially your first sbc build!

355sleeper

iTrader: (4)

ok i got the 1 wire alternator on and it is finally charging.
got my tach installed with shift light as my factory tach is off by 1500rpm.
i have to run the nitrous line up under the car and wire the selenoids and im done with wiring.
i also have to get my fuel line off the upper radiator hose.

this morning i picked up a quart of teal paint. i ditched the 6 inch cowl lift off for an iroc z hood. should look pretty good once i repaint the hood. louvers are being repainted with SEM flat black.

the weather took a dive from 70s to the 30s, so i wont be driving it until this weekend most likely. im going to switch the stock fan out for a 3000cfm fan i have laying around also. it has to be better than the piece stock one

355sleeper

iTrader: (4)

got the louvers painted, did 4 coats total. they look as good as new

budget builder

iTrader: (3)

man you have got to be kidding me. You did that supafast!!! I seen the vid and I love the digi-gauges where did you get them from and how did you wire them in. and congats on your first build although you did it at break neck speed! what is that I smell? could it be gas, exhaust maybe, oh no someone just lit the whole street on FIRE!!!!!!!!!!!

355sleeper

iTrader: (4)

thanks man, it was my first v8 build, ive done a couple dsm motors. the gauges are summit brand water temp and oil pressure, they are actually real cheap. the one on the left however is an aem wideband o2($200) i havent seen your thread in a while, how is your build coming along?

i did get the first coat of body filller on the hood, should get around to painting it this weekend. the track opens next friday, im hoping to go

budget builder

iTrader: (3)

My build is coming along fine its slow going b/c of work and church obligations but I am FINALLY ready to pull the 305 out and strip it for the harm. bal. and time cover then I can go ahead and finish the vortec. but your build is moving alot better than mine. Keep up the good work!

355sleeper

iTrader: (4)

getting ready to sand my third and hopefully last coat of body filler(big dent on body line) then its time for some primer and bust out the guide coat and wet sand with 1000 grit.

as long as i have the hood painted and on and the car doesnt over heat with the 3000cfm fan, i will be going to the track on the 20th. i will be trailering it as the closest track is an hour away and im on a stock 10 bolt still. i should have a set of drag radials laying around to put on it, i doubt a set of mt et 28x13.50 will fit. but ill see what else i have laying around.

ill post results soon. and take a pic after i get the hood painted, on the car and outside

355sleeper

iTrader: (4)

i got the hood all sprayed along with 5 coats of clear. will get to some pics real soon of the car all cleaned up.

dads letting me use his mickey thompson et streets 28x11.5s when i go to the strip.

its supposed to rain this friday too, i really want to take the car. i guess ill see what happens. im shooting for 12.8s to 13.1s with the "s10 converter" i will be jetting the selenoids down to 100 shot to be on the safe side of things but i will not be using it until i get some miles on the motor.

355sleeper

iTrader: (4)

got the hood painted and bolted on last night, i am missing a the striker for it, so i ordered that last night. i also got my permacool 3000cfm fan on and that thing pulls some air. hopefully between that and the water wetter it will keep it cool(like 195 to 200 area)

aside from that its ready to go. will add the pics in a second

2 out of the 4 cars in the garage now move under their own power

92firebird 305

So i have some questions i have a 350 bord .30 over with a scat crank polished lt1 cam in it 350 tbi heads with new valve springs ported and polish on the heads how much power am i looking at im hoping for over 300 to the tires and 320 tq

92firebird 305

i also have flat top pistons trw brand would she my compression be you think 355 flat top with lt1 cam what hp you think with 193 tbi heads ported and polished

355sleeper

iTrader: (4)

honestly i dont know enough to make a great judgement, nor would my opinion be as accurate as others.

300 to 325 hp and around 350 ft lbs @ the FLYWHEEL

i know nothing about your carb or injectors, intake, or exhaust. what is the part # for pistons and what thickness gasket are you using? how about your heads, have they been milled?

92firebird 305

heres the link to the piston http://www.summitracing.com/parts/SLP-WL2252YF30/ and i have tbi rgiht now i have 3 inch flowmaster system on my car but im gonnna add headers on the 355 they with be the hooker 2460s the heads where ported and polished with new valve springs i dont know about the head gasket yet the shop thats building it just got it today
