I have a 91 camaro rs that i have pulled the 305tbi and installed my 85 reman 454 i have installed a low profile intake and valve covers and headers with a 4qt oil pan. i have not figured out what carb i am going to go with or what size??? I have concerns with the fuel delivery system as well i would like to run an electric pump but not sure what will work well? not looking for a drag track only car just a clean bbc cruiser.

 

A 750 CFM will be fine.

The factory fuel pump will work but you need to regulate it down to 6-7 psi fuel pressure and it's best to use a bypass regulator. It will return the fuel not required by the engine back to the tank and will take the headhead load off the pump.

I don't know if your 91 has an electronic transmission or not. If it does then you need to install a TPS on the carb so that the tranny will know the throttle position to shift.

 

on my swap the stock block mounted fuel pump worked fine for me i just took the stock one out of the tank and put a piece of hose to replace it. i also used moroso solid motor mounts(the guy at summit told me there were two sizes like a taller or shorter set so i grabed the shorter ones) and with a stock intake and carb i was able to clear my stock hood with a little stubby filter.

 

I have a 700r4 with electronic ovedrive i belive 4th and tq lockup are electricly controlled . I found a electrical control box that would let you adjust the lockup with a dial in the car. I would like to run the electric intank pump so a regulator would be good. Is there any specific part number for a regulator that you know will be perfect?

 

sweet deal I will try to do the same but i do like the looks of a 4 inch cowl hood just not the price.

A lot of ppl recommend the Mallory pressure regulator. Sorry the part # skips my mind right now, something like 4309.

 

that sounds like right part number. i've already converted my tbi 305 to carb, and thats what i used. it made a world of difference. hopefully gonna get my 454 after the new year. I'm eventually gonna put a 4l80 in and a 14 bolt rear end. both out of a 2000 3500 van. great deal on the van. a buddy of mine is gonna sell it to me for 800. i'll rebuild the 350 for my tahoe, then take the body to the scrap yard and make half my money back. then i will have a near indestructable drivetrain. cant wait!!!

 

the 4l80 is a LOT bigger than the 700r4 and 4l60, youre gonna have to modify the trans tunnel quiet a bit to get it to fit in there...

 

yea i know. already have plans for the torch and hammer to stretch it out some

 

i think it requires a bit more than "massaging" more like cutting peices out

 

i dont have a problem with that. not to sound cocky, but i'm pretty handy with a torch and welder. and since my car pretty much came out of the woods, i have no problem cutting into the transmission tunnel

 

then you have 1 up on a lot of people on here. the majority just say "well i want to put this and that in my car" without actually planning or making sure it will fit or work, or whats required to make it fit and work.

 

Good luck with that rear end.

 

i've actually been planning this for a while. i've done all kinds of research on this. i know that it would be so much easier to just go ahead with a th350 or 400, but i really want that 4 speed with the lock up converter for the drivability. the only problem i've come across is the computer controled shifting. i believe i found my solution at rosslertans.com. they have a box to plug in and make it manual shift. we'll see in time i still have a ways to go. i'm actually more focused on getting the huge rear end up under the car and possibly a custom 4 link i've been drawing up. lots and lots of work.......

 

Cool show us some pics when you get them both in or as you're getting it done

 

id suggest taking a lot of pics and doing a write up an exactly what it took to cram a 4l80e and 14 bolt in a third gen.

 

yea i will definately have to do that. it will take a while, do to the fact i have a new son on the way. plus i am only a diesle mechanic. lack of money is the reason i've done so much research. it's the only way i can feel i'm getting any progress done. so when i do have the money, the project should be a breaze... lol but we all know how that goes

 

Congrats on your new son, just do anything you can do before the new arrival, gonna be some long nights at times lol,but it's all well worth it. Best a luck

 

thanks.

 

since i do have a electronic transmission is there any other way of doing it withought a tps on the carb??

 

welcome to big blocks dont give up im really starting have alot of fun with my car if idont get ticket iwill be lucky there is black marks all up and down my street be safe with it too terry

 

well i did mine without any tps. it does fine, it just holds the gears a little longer when it's cold. but the cool part is i catch 2nd just about everytime it shifts. especialy when it's wet out. it will actually get crooked when its wet. but once it warms up it drives normal and shifts alot smoother. you will however have to get a lockup controller. it will not lock up without it. summit has them pretty reasonable

 

 

Thats where im at i have the patriot headers that i will modify to work then fuel systme will be installed then electrical and cooling. not sure what carb to get yet or what to run with for pump. I have a long water pump on it now with brakets for passenger side alternator mount and drivers lower for power steering looks like stock ps pump will clear steering box.

 

i have a 1988 rs but i took out the v6 and put in a 454 bbc and a 4 core and that has 3 fans on it two 15's and a 12" and it still over heats i have changed out the thermostat to a 160degree from a 195 dagree and im running 97 octine and it still over heats only after 4 miles .... how can i get it to cool down to 200 i need some help on this ..... o ya it has a bw tranny so 5 on the floor

 

I use a Big 2-core(Ron Davis) radiator with two rows of 1.25 tubes and well shrouded twin s-blade w/2500 cfm(@25amps)each puller's, and the 55ghp water pump, no stat, runs 170-185 deg w/one fan running at idle in 105degree Texas ambient. Only seen 200 once after some high revs then cut on both fans and it cooled to below 180 in less than a minute.

 

I'm planning on a similar kind of build but a couple steps back, my uncle had an 88 gm dually sitting, w a rebuilt tranny and motor (believe its a 454) before it was parked, planning and researching to put it in a third gen, any big forewarnings, problems I could be surprised with?

 

yes get new springs and shocks ..... new cooling and you got to make it fit perfect ... and reseal every thing ...... o ya guys i got the ****er running BUT one of the water pump seals blew out .... the guy who owned it before me reused the old seals ..... im going to make this the best and meanest third gen here in tucson

 

Thanks, that's good cause I planning on doing suspension anyway, getting maybe a hotchkis kit or something of the like.

 

Were you able to fix your cooling problem? Tucson throws down some pretty hot temps like here in TX. On a different note, what did you use for engine exhaust(manifolds, hedder's)? Any pic's of your ride with the BBC?

 

Be sure and figure out which way you want to go as far as exhausting goes. There are some choices, Hooker's, Patriot, Ed Quay, or custom fab(think about clearence for oil pan, starter,steering, ground clearence). What are you planning to do with the car? Street/strip, daily driver, or full competetion, or what? Does your car have t-tops? Even if it doesnt, frame stiffening(sub-frame connectors or something) is recommended. Just remember, its bigger, heavier, and stronger(torque) than what was originally intended. Good luck.

 

I don't Have the car yet. Saw an article in super chevy bout a bunch of low budget builds three out of the five were third gens. The more I look into these cars the more I liked what I saw. The plan is to be a street/autocross Menatilty. So i am anticipating to reinforce the frame. As for exhaust looking into a banks twin style of setup but nothing is in stone yet. This is my first project and want to do things as close to right without wasting money. W the help of some mechanic friends I'm hoping to do as much of the work myself.

 

still have some more parts to get like fuel system and cooling and some more odds and ends. would like to get subframe connectors as well. just try to do the swap on a very low buck will get engine running first then upgrade later. thinking of going with a 750 holly double pumper or a cheap summit racing 750. not sure yet?? gets pretty cold(-20F) up here in ND so i hope overheating is not as easy to do as if i were in the desert states. i had fitted the exhaust headers partriots to the engine after cutting the passenger side and bending it and welding it back up it fits perfect. stock trans 700r still thinking about a electric speed sensor kit from summit for the tq lockup. radiator is going to be the one that fits the best and i hope for good cooling. had to go with long water pump from the local store could not find a alternator mount on the passenger side for the short pumps sucks". but i think i will still heave plenty of room for the bigest readiator and electric fans setup too. will post ned pics soon!!

This is my thirdgen with a 498 with a 12 bolt fabricated to accept the torque arm. Never did get a full , ***** to the wall run . Here I had traction problems and my trans was acting up. http://youtu.be/DaR8NA1sDI4

 

I like the vid of the 12.7 pass where you ran down the Mustank better.<iframe width="420" height="315" src="http://www.youtube.com/embed/KzYOGfKNctQ" frameborder="0" allowfullscreen></iframe>

 

I tried to post a link, but i suck. Your ride looks just like the car in 89454's sig photo. Not saying they are the same, just look alot( both in primer, same hood, wheels) alike. Nice ride... both of them.

 

Mine is a short deck 454 with a truck th400. Stock single electric fan, long water pump. Everything fit and with the stock iron manifold, qjet, and low truck filter, it fit under the hood. I used the stock FI pump with a keith black regulator. Had to build a trans crossmember, headers, exhaust, and get a driveline made.

Good luck with the build!

 

Any updates? Pic's?

 

Thanks, I guess he likes the iroc/z28 stock wheel look. I enjoyed spanking alot of the "nicer" rides in town. See we're at 4+ elevation here and cars loose(or actually gain) a good second in the 1/4 mile. I recall racing a z06 corvette and beating him and he ran me again because he missed a shift. Well same outcome.

 

Ya im planning on using what i can from the truck then filling in the rest of the puzzle from there. What would be a the cost of having a driveline made? How does the third gen rear end hold up to a BBC? Thanks for all the heads up.

 

"Driveline" made? I'm not sure what exactly you mean. As far as will the stock rear end hold up? Depends on how hard you beat on it(hard launches vs none, plus there's slicks vs street tire), but mostly... not for very long. Even with axle and gear and posi upgrade's the 9 or 10 bolt rear ends are strength limited. There are plenty of aftermarket rears available for 3rd gens but unless you plan to fab one yourself, which is very doable by the way, you can expect to pay more than $1000. for one new retail. If you ment 'Driveshaft', you can have on made for about $150-$500+ depending on type of material and size and other options.

 

I'm just assuming that as well. From comment 41. Appreciate the advice, it's been really helpful

 

Is anybody able to see the pictures im posting???
