and the mix matching woes begin!!!! I got the flywheel for the motor and I guess the bolt pattern on the crank shaft for the 1985 305, is different from the 1989 350. I guess I will head on over to the forums about clutches, trannies and motors and see what I can find. If anyone who reads this happens to know what part number I would need for the 1989 350 (T5 tranny) I would love and appreciate it!! also, would you know if the clutch assembly is different also? or is it the same. the outer bolt pattern looked identical, just the bolt pattern for the crank shaft was different. oh well......

ericjon262

should be the same as both engines *should* be one piece rear main seal blocks, the flywheels only bolt on one way, have you tried rotating it around several times to see if the holes ever line up?

KBD85

yeah the whole bolt pattern is a bigger bolt circle. this motor was "rebuilt" by the previous owner, I wonder if it is even a F body motor??? curious if it came out of a truck or something as the heads were a bit different than the machine shop thought they would be. thanks for the help !!

ericjon262

is your crank flange round, or a more free form shape?

KBD85

thanks so so so much for the help!!! this motor stuff is so forign to me. i took some pics for ya. the first three are of the 305, the second three of the 350 the last two some cast numbers off the 350.

thanks again!!!!!!!!!!!!! KEN

KBD85

shots of the 350

KBD85

castings of the 350.... also, the 305 measurements from the pic reads about 1-3/4, and the 350 seems to read about 1-1/2

ericjon262

well, that block is a one piece rear main seal block, your 86 block is a two piece. so you need a flywheel for a one piece RMS engine.

Yep..just get a flywheel for an 89 305 car..no 350 f Body car is going to show a flywheel because they didn't exist...sorry Ken,didn't think of that earlier..coulda saved ya some time and aggravation..pm me if you run into any wire harness questions..

ericjon262

only other thing to be concerned with, is if the engine is internal or external balance, IIRC, 3rd gen era engines are all internal balance, and later, vortec era, along with the 400 smallblocks, are external balance, but I could be wrong, it's been a long time since I thought about building a SBC.

KBD85

thanks so much Eric and Timmy!!! so good to have willing knowledge available. With out friends on this site I would have thrown in the towel. Probably would not have even attemted this build. One more question. I need a clutch assy and have one order. Is it going to be the same? or is it different also?? I will go in today and see if I can have them look up the flywheel suggested. I am going to have to do some research and see what the diff is between two piece and one piece. It has been fun learning some mechanical stuff. thanks again so much for the help!! makes learning fun rather than frustrating.

Ken

TGO RULES!!!!

so I looked at the pics. I think I see what you mean by one piece and two piece. Very interesting!!! thanks again!! you guys rule! and Timmy I will PM you WHEN I come across the wiring issues (hehehe) I am pretty sure it will challenge my patience

KBD85

Well, now the scary part begins. I got the motor in the car. Ive been sizing up stuff. I already have issue... i know shock face... i had to remove what i think is the oil pressure sensor. it screwes right by the damn knucke i need for my clutch. which is just above the oil filter. anyway, on my 305 it wasnt there, so I need to see where the hell i can put it. Here i have some pics of it going in. thought it would be cool to shot some sequencing of it going in.

enjoy......Ken

Please don't take offence, but to put stock exhaust manifolds on an engine that pretty should be a crime. That whole engine bay looks too good to have those cast iron logs in it.

KBD85

I totaly dont take offence, cuz i absolutly agree 100% im just running out of money and my goal is to get it running, and i promise i will get some headers! sorry for the nasty stock manifolds...

TIMMYS89GTA

I think you can put that sensor on top of the block next to the distributor..

Beautiful car man

KBD85

yes i just found that on yet again this wonderful site!!!! thanks to all TGO peeps for so much info. if you can figure out how to search it ive decided its on here!

KBD85

Thanks for the compliments!! Im so ready to get to the body part of this build!! I tried to bleed the brakes last night and one of the bleed off vavles snapped off!! ARGH!! anyway, its not a daily driver so I can take my time I guess, just want to drive it in the spring.

86_irocz-28

Same here spring is the deadline but not sure if if it will love the work on the front and rear bumper

KBD85

So here is the next mystery for all you wire peeps! I was wondering what to do with this issue. It appears to be fused / melted together. and the obvious wire showing. Can I just cut and splice them together? or do I need this plug here. Not sure what to do. I put three pics in from close up to further away so you can get a feel of where it is, which is back at the firewall.

ericjon262

colors look like it might be a/c related, but I can't say for sure.

TIMMYS89GTA

iTrader: (28)

yes Ken,you can splice them if needed,,and eric is correct,they go to the hvac system.

KBD85

ah yes, I didnt even think of that till Eric said that. I had motor harness on the brain. thanks guys!!!!!

Ken

KBD85

alright, next question. this is the wiring from the 85 alt. and also the 89 alt. my question is on the 85 its obvious which one is grond cuz they do it right from the plug. but the 89 alt wire and plug wires go thru the harness. I need to splice the 89 plug onto my 85 harness. Do you know which color is grond and which color isnt? heres the pics. I am guessing the large red one is power, and the smaller tan one is ground. the pic where just the wire is showing is for the color of the 89. There are two pics of the 89 and one of the 85.

KBD85

one more question. and I have a feeling this is a stupid one, but im no mechanic and this is totaly kicking my butt!!! I SOOO want to get my car running. anyway, my 85 had one type of heater hose and the 89 has another. I dont even know what it is or is called, but here are the pics of both. I would like to not have the big plastic thing, but i dont know what it does. My 85 didnt have it. So i have the 85 pipe with no "T" in it and the 89 had a "T" in it.

thanks so much !!!!!

MAN I LOVE THIS SITE!!!! so i did more digging and found some info. im thinking this thing is what runs the heater on off switch for the 89 models. Therefore im guessing since my car is a 85 i should NOT run the valve, which is the "T" pipe. am i thinking right??

TIMMYS89GTA

iTrader: (28)

Right Ken,you don't need the heater control valve..on my 89 gta I ran a corvette tpi 350 w/the aluminum heads..I just ran the heater hoses directly through the coolant system and didn't run anything off the throttle body..never had any issues..and was a much cleaner look.
On your alt. plug,I believe you're correct but,can't recall for sure right now..might wanna double check schematics..

KBD85

K.. Thanks so much Timmy. I think I'm starting to get this whole engine thing. Takes some time to just understand what it all does. And again this site ROCKS for the little information I need to connect the dots.

KBD85

K, I may have to pop over to the engine threads, but thought I would throw this out to the 2.5 people watching this thread before I do so here is the deal, I have searched all thru the engine threads and cant find my exact answer, maybe I am searching wrong, so ill ask here before I start another thread. I cant seem to find a starter that fits my T5 350 setup. First of all as I already know, the stock automatic starter is too big. So O'reillys tried to find me a smaller nose starter and now the hole pattern is narrower than mine and about an inch away from the engine block to mount it to. This is my third trip there and obviously they don't have a clue. So it is time for the professionals (you guys) to help. I would LLOOVVEE someone to give me a year and model of a Camaro or firebird in which there was a T5 manual so I can find this, OR a part number if you have one. I do tell O'reillys the year and model of the Camaro I got this trans out of, but it does not give us the manual trans starter. anyway, chew on that for a while, ill also keep digging.

thanks so much guys!!!!

Ken

ericjon262

the 305 5 speed starter should work fine. I'm surprised that they aren't the same.

KBD85

the starter was out of the 305 700R4 car. and when I tell Oreillys I need a starter for a manual 84 Camaro it doesn't tell you there is a difference. I may need to go to a real auto parts store hehehe

ericjon262

try a later model, like a 90 model or something. there's also LT1 starters that are way more compact, and IIRC are a bolt in and go swap.

KBD85

I will keep that in mind, apparently NAPA has found one, and will be at the store in the morning. If that isn't the right one I will ask for the new stuff, that is a good idea. Thanks so much for the help guys!!! I am learning a lot with this motor stuff.

KBD85

Alright, this is taking so long! between work and getting things done around the house, i dont get much time. So, my next delema. even tho ive taken four million pictures its funny how you seem to miss an important one. I am putting the wires on my starter and they go thru a metal tube with two tabs on it that apparently bolt to something. I cant seem to figure out how it goes, and i cant find a pic from when i took it off. Do any of you have a pic of how this is secured? im sure it is to keep the wires from the exhaust. anyway i have a few pics that i did have (kind of crappy pics) to let you see what im talking about.

TIMMYS89GTA

iTrader: (28)

Ken,the firewall side of that tube bolts through the second hole up from bottom on the bell housing (passenger side)
The front of it I believe slips over the threaded stud on front of starter..not the little one on the solenoid though..you don't want to send power to it..

KBD85

K, that makes sence. I will check it out tonight. thanks !!!

KBD85

SO SO CLOSE! alright have another engine question for you engine smart people! i am getting ready to put the distributor in and notice kind of a huge difference. the 5.7 89 seems to have some side cylinoid or something, and the 5.0 85 does not. I am trying to use the 85 harness, which for the most part seems to be working great. My question is, can i use my 5.0 85 distributor in my 5.7 89 motor? im guessing I can, but I want to be sure, and you guys would know that. thanks so much for all the help!!! one day I promise i will get to what this thread is titled, "body" hehehe. thanks !!

Ken

p.s. i have posted pics of the two distributors in the motor and you can see the one has the cylinoid and the the other does not.

ericjon262

either one should work fine, the larger one has the ignition coil integrated into the cap, the smaller one requires an external coil.

KBD85

whew... thanks Eric! this engine stuff is stressing me out. Im so scared its not gona start hehehe. I guess we should find out here in a week.

thanks again!!
Ken

ericjon262

no prob, I would match the distributor to the computer you're going to use to run it. that way there for sure won't be an issue.

Ken..no updates?

KBD85

almost my brutha, almost.... was going to see if it would start this weekend, my grandmother got in a fender bender (she is fine, just a little hood creaser) so i had to sort that out and ofcourse im fixing it for her. now we are just waiting for insurance so im going to try to get the bird to breathe! i have to splice two wires and redo a few rotton vacuum hoses. Im not very confident in myself tho. Im wondering if im going to need to flash this computer (the 85 305) cuz the 89 350 computer had the chip in the key. which i obviously dont have now. Dont know if that would effect it or not. the plan is to try it with the 85 computer and see what i get, then if it seems really sh!tty then i will swap computers and see what i get. Thanks for the drive tho Timmy!!!!!! i realy want to get back on the body work BAD!

Ken

p.s. im sure ill be asking a ton of questions when i try to start this beast!

TIMMYS89GTA

iTrader: (28)

If you're using the 85 harness and ECM you shouldn't have any problems with the vats...only problem you're going to have is your 350 is going to run a little lean because your 85 computer thinks it's running a 305 still.

KBD85

NICE! that is good to know. I just want to start it and see if its going to work. from that point I may have it flashed or something. what would you recomend?

TIMMYS89GTA

iTrader: (28)

don't need to have it flashed...just get ahold of one of the places that does the programming..what they do is program an adapter chip that goes into your ecm and your original chip just plugs into the adapter..just give them all your info and they will hook you up..I know theres a few places that do this..when I had one done for my GTA way back when I had tpiparts.net do it but they weren't the only place...not sure if they are still around though..I was pleased with the one they made for me.

KBD85

Nice. Thanks!! So nice having help when your doing crazy things for the first time. Cross your fingers for me that it all works this weekend.
