I have an 1989 Camaro. I started my swap in December. I removed the 305, the ecm and most of the wires except for the few i need for the new motor, and i removed the a/c ( dont need that windows are great) and heater blower ( i live in florida dont need that). next i cleaned the enngine bay sanded it filled the holes in the fire wall, and then painted the engine bay a flat black. right now the new motor is a 87 roller motor casting number 14093638 its on the engine stand it just about down i'm hoping to have it in buy next weekend. here are some pics will have specs when im done and many more pics and better to come

Here are some better pics the motor will be in this weekend i taking pics of the motor tomorrow will post them and them after install also

Mr355

Thats the exact thing I'm doing! My 355 is goin in tomorrow. Except i couldn't afford the paint for the engine bay. I hope you plan on headers.. my advice if you go with headers, put em in before the motor. Its WAY easier. Nice choice, and good luck.

lillis375

iTrader: (3)

thanks bro beleive it or not the paint cost about $30 it just took for ever to sand it the prime it and the i painted it with an automotive spray paint and it came out great i even tested to see how strong it was and perfect so if the headers take any off i got some to fix it.

Mr355

30 dollars? I must have been lookin at the wrong paint.. the stuff i saw was like 120 for the entire thing. But the thing with the headers... with the air conditioning it might be hard to slide it in on the passenger side. But my ride didnt have ac and it was a tight fit. Why did you decide to switch to carb?

lillis375

iTrader: (3)

i removed the a/c i dont need it windows are way better, i know how some people are on here about all the smog laws but florida doesnt enforce it so that not an issue, i just like carbs simple to work on a much cleaner look, i dont need a million wires and harnesses all that stuff. what about you?

Mr355

Yea man i got tired of the computer issues with not enough air in the exhuast, too much air.. But eventually the 305 went poof and i finished my 355 so i went that way. I like the way the carbs look, and they are so much easier to work with. And the wires were gettin extremely annoying. I hope it works haha its my first build. Its going to be interesting with emmisions though.. Arizona is pretty strict.. and i got 3 foot pipes dumped at the tranny. No mufflers/cats and i got some Mickey Thompson slicks goin on this weekend too...

lillis375

iTrader: (3)

man that sounds great. yea this is my first build so im hoping it goes good also. after this is down im goin to start with that chassis and suspension i think im goin with spohn for all that then the interior then paint maybe a 12 bolt rear end but that will probaly be next year when its tax time again

Mr355

Yea man i hear ya. I got a lead on this 95 z28 posi axle with disks for like 200 dollars. Just gotta sell some bass equipment. But i cant decide on the suspension/chassis. I've been looking at some Eibach lowering springs and some new shocks and them Polygraphite performance bushings. But i dont know if my slicks will fit in the wheel wells. But i suppose i'll cross that bridge when i get there.

Well everything coming to the end here are some better pics, motor is complete will take pics, going to put it in this weekend, then do the afpr, tune and bring it to my buddies shop for the tcc lockup kit

so what does anybody think so far? anybody like it dont like it

blkfirebird91

iTrader: (-1)

i like it wish i saw it before lol.

but how do you hook up the fpr because i have the same one. like do i have to force feed the fuel back to the tank or to i just hook the return line to the fpr?? where it says then another line back to the carb. also what did you do with all the wires?

lillis375

iTrader: (3)

the hose coming out of the bottom of the afpr is the return line, on the right is the fuel coming in from the tank and the hose on the left is the line going to the fuel log into the carb but i need to cut it and put the gauge in the line so i can see the psi, the hardware uses is 3/8 thread to 3/8 barb (or nipple ends) and 2- 3/8 block nuts, and the 3/8 braided fuel lines and on the fuel lines soming in i used a 3/8 for the fuel inlet and 5/16 for fuel return i have to find the receipt cause it was a different fitting the the afpr lmk if this helps just hook up the return line and adjust wires i removed the ecm anything that went to a sensor i took out i save the wires to the disty starter alternator oil pressure temp the lights and a couple of other things all these went itno the firewll on the driver side i kept all the wire just in case then i rigged that vats and i need to do the lockup coverter tom.

yes that helped and made sense to me thanks for your help and btw nice job with your motor i like it.

lillis375

iTrader: (3)

thanks bro pm me if you need anything else i edit that above about the wires i didnt see that part at first

lillis375

iTrader: (3)

What does eveyone else think i would like to hear from others

iTrader: (5)

I'm thinking of doing the same thing with my 91 RS. The only question I have is what do I have to do with the in tank fuel pump? will it work with carb? I have a walbro 255 or do I need a fuel regulator?

lillis375

iTrader: (3)

a carb does not need the rate of fuel the FI system needs so all you need is something like what i have the mallory 4309 adjustable feul pressure regulator hook that up and set you pressure and you will be good to use the intake fuel pump

z28gsxr

iTrader: (5)

Great thanx so to do the tbi to carb swap i do not need to drop the gas tank right? i thought i had to change the fuel pump.

19 z28 92

iTrader: (3)

No....If you want to keep your in tank fuel pump, get a RETURN style pressure regulator.

The most common one is the Mallory 4309.

z28gsxr

iTrader: (5)

Thanx that was the only thing worrying me.

89rs454

Nice Motor man great job.

lillis375

iTrader: (3)

thanks you cant wait to fire it up hopfully this weekend

89rs454

I would love to fire it up where do you live

z28gsxr

iTrader: (5)

So after swapping in the new motor and converting to carb and removing the computer and all wiring do I still need to overide vats?

lillis375

iTrader: (3)

Yes the VATS still has is own module that needs to be overriden go to the tech articles and follow the directions for VATS bypass

z28gsxr

iTrader: (5)

Damn not what I wanted to here. let me search on how to override it. By any chance do you have a link?

z28gsxr

iTrader: (5)

Will vats be an issue if i have the correct key with the matching resistor?

z28gsxr

iTrader: (5)

https://www.thirdgen.org/forums/post...042-post6.html

I found this. It says that the computer will look for a signal from vats before starting so if no computer it won't look for the signal and start anyway? Atleast thats what I gather from this post I found

89rs454

Yeah if you take all the computer crap out it should work fine being a carb engine.

z28gsxr

iTrader: (5)

great thanx

lillis375

iTrader: (3)

yeah i think i was mistaking the vats should not be a issue i just read so much stuff for the swap sorry about that

lillis375

iTrader: (3)

So i got the motor in i will have pics tom. got the alternator,starter, battery, dizzy, fan, fuel pump wire up, had to bypass the starter enable relay cause of the vats. then when the fuel came to the fuel log i had a leak so i will deal with that in the morning a couple of little things to do then i hope it will fire up

lillis375

iTrader: (3)

so i still cant get it to start i think my timing is off it just cranks will not fire up so today i gonna work on it and see where i get will let everyone know

lillis375

iTrader: (3)

so i got it started fouled a plug with bad gas but it running sounds like a beast will have pics and video tom.

lillis375

iTrader: (3)

z28gsxr

iTrader: (5)

looks good so how's she running? I've been slacking off on my swap. I got the 350 carb in everything mounted. but i have not installed the trans, distributor or plug wires. I'm also going with SS fuel lines so I need to figure out how i'm going to run them.

lillis375

iTrader: (3)

its running great just finished tuning today. it a beast goin tom. to get the drag radial on and then put some miles on her and see how it goes she has only gone around the block

z28gsxr

iTrader: (5)

nice congrats. I can't wait to drive mine. What did u end up setting your fuel pressure to?

lillis375

iTrader: (3)

I put it thru the top hole from the windshield washer fuild container cause i just took it out. so nut and bolt and done

z28gsxr

iTrader: (5)

no I meant what pressure did you set it to.

lillis375

iTrader: (3)

6 psi runs great

92Rallydad

I was happy to see your thread. We are just getting ready to order a 383 Blueprint Crate from Summit and will be starting our project in the next 2 weeks. We are replacing the stock 305 TBI on the 92 rally Sport and look to do the same as you however we need the heater in Colorado but have not yet decided on the AC. Put in a 10 bolt 373 Posi from a iroc 2 weeks ago, big change over the 308 gears but whines under load. Thanks for the great info on the Mallory, did your 89 with TBI have a sufficient return line fro fuel or did you run another?

DartByU

So, if you pull the ECM out does that cause the electronic speedometer to not work? Doesn't it need the ECM to function? How about the other gauges?

lillis375

iTrader: (3)

well i have a mechnical speedo, do i dont know what would happen with that and as for the other gauges i went aftermarket

lillis375

iTrader: (3)

srry i didnt see this post the other day the return line was fine i have had no problems

92Rallydad

Your Engine looks great. Ended up getting a good rblt 350 instead of the 383 and ready to start pulling the 305 tonight! Excited and scared at the same time. I am concerned about all the electronic stuff that will be disconnected and not used anymore. Did you have any good reference book/site/article to tell you what needed to be hooked up or bypassed in order to make the ECM happy? Thx.

lillis375

iTrader: (3)

no just started taking stuff out and hope for the best
