first off...the reason i built this 283 was because...when you enter "283 performance combo"(or something to that effect) into yahoo and search you will find nothing positive said about this motor ...for stupid ignorant reasons.
That said...i come from a family of chevy and its peformance ... big block chevelles dominate this town...im a 3rd gen. mechanic ...@ 19 years old....and yesss i own an ls1....look what these morons had to say

"no real reason to build one today" hahaa

...anyway....heres what i did...

283 bored .040

k&n 14x4 with X-stream lid

Crane blueprint cam of the L-79 327/350hp .447 lift [hydraulic lift,not roller]

Vortecs off a 98 5.0/305ci.heads are slightly ported&milled[no roller rockers]

Valve sizes are 1.89/1.50, the biggest a 283 left the fac. was 1.72 int. valve

Edelbrock Vortec Performer-RPM air-gap

650 Speed Demon

Hedman long tubes, into a custom 2.5in. x-pipe fed into 2.5 40series Flows

4 speed T-10, 3:42's; 26in mickey thompson Et Streets

this motor yields about a 10:1-10.25:1 comp. ratio

at the track launching the truck @ 3000-3300rpm range i knocked off 13.5's shifting @ about 7300rpm....this bad boy ran like a champ...not bad for a 4.6 chevy...lol modular ford 4.6s cant even put these number up ...and thats with overhead cams...RIDICULOUS!!!! this motor winds up like the little beast it is.... using a roller cam setup, a little more compression and possibly some aluminum heads...theres no doubt in my mind you can have a 8000rpm screamer. Doing the numbers i think my motor is makin about 315-335 hp, and about 300 lb/ft. of torque...id say thats pretty damn accurate.

Not to be rude, but I agree with what was said in the article. I wouldn't like to give myself a 67ci penalty right out of the box by going with a small motor when a 350 could be built for the same price.

What were the reasons you built a small motor? Just trying to get some insight into your build. A bigger motor always seems like a better alternative to me, so I'm just looking for your rationale. A 355ci motor could have made nearly a 100hp more just from more displacement.

the 283 and 327 engines were high rpm monsters....now a 350 is a better buld but I am like you, build something different and have fun with it.

If you are just wanting to have fun with the truck, then I believe you are on the right path.

I would put a victor jr intake, swap out the cam for a roller setup, and change the heads as you have mentioned. Throw on some good dart heads on that thing and you should easily be in the 12's on a sticky tire. If the motor pieces are forged, you could put a 100-150 shot on it and be in the high 11's with it IMO.

Good luck, sounds like fun.

you're right about the 4.6 mod motors not going 13.5, but you also have to think those are completely stock and you s-10 weighs a considerable amount less than a mustang, but interesting build none the less! With you spinning that many rpms i think its turbo time

how are the hedman headers working for ya? i too am putting a v8 in a s series truck and am looking for good headers. ive heard they tend to warp?

i got hedman LT's on my car and i havent noticed any warpage, they are un coated but wrapped with header wrap, not sure if that makes a difference

njkid

nice nice are the welds weak or anything. i was talking to a buddy and he said he had them and they warped and the welds around the flanges cracked. how long have ya had them

Teh Wicked

Honestly do your research before you make a statement like that, i personally own one of them slow 4.6 281ci Mustang GT's and when your ready to see what a 3800lb car with a intake, exhaust and suspension will do just let me know. with it being as heavy as it is I have been 13.2 @ 103 with a crappy 60'. personaly friends of mine who can drive alot better have went 12.30's @ 108 with stock head/cam cars with just bolts on, suspension and tire.

13.5, HAH! maybe the 96-98 Gt's mid 13's are easy to reach in the 99+ Mustangs. all it takes is a shifter, intake and a good driver.

ZL1camaro

lol... ru kidding ...it sounds like ur vouching for the 4.6 modular(junk)...first off 1. ford doesnt use anything even remotely heavy duty or strucually ridged to make it a legit 3800 lb. car', the 05 gto is a legit 3800 lb. car
2. ...the curb weight is sumthing like 3478 er sumthing like that...
3. the heads dont flow for **** on those cars like 170-180 cfm stock i believe
4. my couzin has an 03' gt... its a full bolt on car with 4:10's and nitto 275's and its a 5 spd ...after cai,headers,gears,tires,throttlebody,and uppper int. and x pipe w/o cats the best its done is 13.41....and u better believe the boy can shift.the car launches clean at 3000.
5. theres no way u can get a 4.6 in the 12's without porting the heads and getting very aggressive with the motor.
6. as for the 98-99 mustangs those are horrible my friend has 1 with flows and k&n...it runs 14.85 at best....hahahah he cuts deep 15's all day....

ZL1camaro

well this is a 283!!!!! damnit... my grandpa and my dad have told me lots of stories of wicked 283s... and the fact that so many people dont know a whole lot ...makes it easty for them to say things without any knowledge.
1. these motors came with forged internalls sooooo yah
2. so many people have told me theyve whaled and winded these motors alllll day...and they just dont break "theyre lil hard to kill *******" theyre very reliable because of the short stroke.and to back that up its a forged crank so the motor isnt stressed.....this truck was running deep 12.s before i pulled the 350 i had in it....its .040 over with e-tec 200's,crane roller .539/.558 speed pro 10.5:1 ...rpm air-gap...750 speed demon, aluminum crane roller rocker, moroso valley baffle, windage tray...about 430 hp 410tq.

Teh Wicked

Bro, Im telling you. the 99-04 Mustang Gt have been low 12's on stock heads and cams. i have personal friends who have done it!

as for my carf weighing 3800lbs, it does! the curb weight is 3467 yes, now add the Mach1000 Stereo which in clided 4 amplifiers, 2 10" subs and a rack for them all to look nice and its a good 250lbs extra. now add on my 235lb *** and bam look at that 2003 Gt that weight 3807lbs. i know this cause I weighed it.

Please bro do your reseacrh before you start bashing a car you know nothing about. go over to www.modulardepot.com or www.corral.net and tell them guys its impossible to run low 12's on stock heads/cams. if that still isnt proof please come down to Fl and meet me at bradenton and I will show you mine run 13.5's on street tires 18's on all corners and sway bars installed.

ZL1camaro

sry bro this is LS1tech...u know the guys that didnt buy those pos!...theres no research needed,....im goin by the simple fact that everybody know those cars are ****...as far as the weight thing... ok when my ls1 has a full tank and my 235 lbs. in it its a 3900 lb. car...happy!?...."research" is my middle name .... on h.p. tv they put a vortech on a 4.6 stang and put down like 288 hp with headers, full exhaust and cai...when the stock 01 ls1 z28 right next 2 it was putting down like 277,...aaaand on speed vision on tunervision they did the same ...they dropped the 0-60 time from like 5.5s to 5.0s..AFTER A Vortech supercharger!!!!!!

njkid

got any pics or vids of the s10

joewee350

Mildly ported stock heads and a tiny cam....there is no way it is making power at 7000+rpm. Whats the point of spinning that high if it is making max power at a much lower rpm. I didnt even think a hydraulic flat tappet could spin that high without some sort of problems especially if you have stock valve springs. Why didnt you go with a solid lifter cam if you planned on winding it up that high?

Teh Wicked

Wow, I cant beleiev you believe that crap! if I had a blower on my car and only made 288 with a set of headers I would be pissed off!!! As for saying my persoanl daily driven mustang is crap I resent that. you obviously dont know jack about them so why would you say something like that? I never bashed your slow over work 283ci chevy. Hell my car as it sits makes 282rwho N/A with stock cams and heads. Dont believe me you say? I got a video to prove it! I will post the link when I get home from work. Im just trying to educate you a little on something here and not really trying to rub you the wrong way, but it seems you have an ego problem and refuse to learn anything new. im done here...

ZL1camaro

what isnt their to believe....they are plain and simple pieces of ****...if u want to bash a 35 year old motor thats stronger and can handle high rpm abuse then go ahead. All i said was 4.6 modulars dont even run those #'s u with exhaust, cai...they are still 14.2-14.5 cars allll dayyy long! u take it to the heart, and say im bashing...mmk! isuppose. I on the other hand still have more power to be had
1. a roller setup....to make it somewhat retro
2. aluminum heads/more compression
3. valley baffle/ windage tray (i assume u know oil control is crucial @ high rpm) this is easily good for 350hp+

ZL1camaro

VORTEC brotha....with a lil' port ....that MEANS AIR FLOW--->, id hardly call them stock....these things move air...perhaps thats y this motor runs pretty good... head flow is critical...this is why this motor screams.....as for the cam a its the stock 350HP cam from the 327 that winded to 6500+ soooo why r u doubting it doing the same or more on a even smaller displacement motor....

z28fan

283's great nostalgia for me- I had a 66 impala with one, no it wasn't fast.

Sounds like you have a good build, have fun with your truck.

joewee350

Im not a complete idiot. Vortec heads are decent but are by no means high flowing heads. I would bet my heads flow a great deal more than yours but Im not going over 6500rpm. Just because you have a little motor doesnt mean it will wind up like a top and still perform. There is no way that tiny cam is making power up top. My cam is a decent bit bigger and it is finished making power around 6k. I am questioning the ability of a hydraulic flat tappet cam to spin to 7300 rpm. I did not think it was mechanically possible to do it with that cam and not break something.
