ok, i remmeber somewhere seeing a big block chevy, i dont knwo what size, witha Fuel injection system, and a TPi intake manifold on it.

The trick was that it had a TBI intake with a hole made in the bottom of the plenum and the sides of the plenum bolted shut. then a custom prom was burned just for it,



Could this work well guys?

What do you mean Bolted shut? YOu arent making any sense here shane. The FI setup you saw was probably the RamJet setup. Why would you want TPI on anything?

therckid

Nah, the sides where the runners normally went to the itnake manfold were blocked with blockoff plates, and the 4"(i'm guessing here) diameter hole in the bottom of the plenum bolted to the TBI intake manifold... Making the TBI system use a TPi plenum for the looks...


I just love the look of the TPI plenum, and this is prolly what i would do if i were to use one of the 454's this guy is willing to trade.

Stekman

MPFI. Don't hurt yourself over this one.

LJ, what he's describing is the plenum and the TB off of a TPI, sealing the runner holes shut, cutting a hole in the bottom, and bolting it up essentially to a MPFI manifold like the one made by Holley or Edelbrock's Pro-Flo.

I would use a centralized throttle body over a front mounted unit any day.

therckid

multi port fuel injection, ok what is that for, is that what i'm turing the TPI into?

is it good or what?

nidyanazo

Uh-oh

ljnowell

I gotcha. But why? Better off like you said, with a centralized throttle body. Something like the Holley projection of Edelbrock Pro-Flow.

therckid

hmmm..


good point...

iunno i just liked the way the whole thing looked...

iunno tho....

Like I said. Don't hurt yourself over this one.

therckid

hmmmm cool....

thanks bro...


brings me back to the next question, the guy with the 454 says he has some stock old camaro heads, i'll find out later what casting number, but are they worth the flow or can i just port and polish them?

ljnowell

Does it matter? You wont acually get them, if they exist. Go get the parts, and then come back here and post about them. Until you have them, this thread is pointless, as are most you originate.

You already got headers, cat back and 305 TPI. What's that 250 hp? That's almost 100hp more than my T/A was stock. How fast do you want it? Its a daily driver right?

Listen to me man, I wasted two and a half years so far having my car up on jack stands so I could put the 350 in it and do a full resto, and it aint done yet.

I am kicking myself now for wasting all that time. I will never get my time back. I could have just tuned the 305 with bolt-ons and had it painted, and I would have been cruising 2 years ago in a cherry T/A that wouldn't be a rocket but would defiantly been a lot quicker. I would have had the past two summers in that car with the tops off and the wind in my gray hair.

On top of that it cost a phenomenal amount of cash! When I started this project I was only going to spend $4000.00. I have spent $12,000.00 so far, and I am in line with a friend's shop to get it painted this spring (long waiting list). That will be another $3000.00. That's $15,000.00 total and one H E L L of a supportive wife!! With the grace of the L0rd, I am a very lucky man.

Don't get me wrong kid. Dreaming is great. It opens up the avenues of creativity. But, if you want to do something with your car and you don't have a lot of cash, learn to be happy with what you have first. From the pics, it seems like a real nice ride. Do you know how much time, money and no-how it will take to get that 454 into your car? Besides that, FI for a 454 is cheaper to just buy a system already made for the BBC. That way you know it will work.

Why don't you just keep your LB9? You are lucky kid. I bought my TransAm 3 years ago and all I got was the LG4 305. That's about 50 to 60 less HP than your LB9. Change the gear out back to a 3:42 if it aint all ready, and throw in a shift kit.

After the gear focus on getting the body perfect.

Look man I am sorry if I seem like I am going off on you. I am not. And I am not making fun of you, I have read some of your other posts and I just don't want to see you or any one else make the same stupid mistakes I did.

The first one was not appreciating what I had to begin with.

The second was being cocky and thinking I knew how to build a powerful street motor when I really only knew enough to scratch the surface. I have learned so much over the last 2.5 years about the SBC that I think my brain is going to push my gray hair out and make me bald. Guess what, I still don't know all there is to know about the SBC either.

I could have cut down on a lot of the errors I made on the engine if I had bought a book on 'hot rodding the SBC' (or something similar) from Jegs or summit before I started building the motor. Do a lot of research, buy books magazines, READ! Use the search button.

This is my first successful build up (I have started others but they were daily drivers and that doesn't work, its got to be a toy or it aint worth hot rodding cause its just going to get wore out and traded in and your money lost). It will probably my last build up too. Do to the amount of time and money it took, I just want to drive it and enjoy it. Funny, I did research the tranny and that is the only part of the car that I believe I didn't make any mistakes on.

Stop driving it in the snow! Park it for the winter! Take care of it dude. buy a $100.00 beater. Trust me, in the spring when you get it out of storage, and only drive it on weekends, you'll appreciate it more.

If all else fails nitrous is cheap. lol!

Id personally steer clear of the big block for a street car. Too big for the chassis.

What I would do is take the tpi intake and send it off to be recycled into soda cans or something. Id then get a carb style single plane mpfi intake and use that in place of the stock one. In addition, Id get some sort of carb or tb hat so I could hook up the MAF and all its plumbing. Id then get a decent efi friendly cam for it and also clean up the heads. After that, get some better valve train components, good injectors, and prom equipment and youd be left with a healthy 305. If it pukes later on you can then get a 350 and enjoy even more power. To me thats a much more reasonable and easily obtainable goal then swapping in a big block.

Red Devil

So why are you still running a TBI of all things D?

TPI

always someone hating on Tuned Port

89RsPower!

Jesus, everytime I see a post by this guy I just gotta look, its like a car crash. My brain hurts now.

RB83L69

Maybe this might be a suitable approach?

my3rdgen

RB83L69, that is crazy. Where did you find that pic? They could have at least put 2 carbs on that lol!

RB83L69

Believe it or not, it was on ebay.

And as if that wasn't bizarre enough, somebody actually paid money for it!!

VetNutJim

That looks like the "TunedPorteretor".
I've heard those things reun really well.

THEGENERAL

UMMM Shane where are the pics of this mystery big block your getting this week ??

Or how about just some pics of the 400 you bought last week ???

HMMMM i gotta call again because i dont believe this engine or the other even or ever did exist but if you cant show some pics of casting numbers and you in the pic with the engines then i will withdraw this post

Red Devil

RB, you saved those pics from that ebay ad!! That was sidesplitting. I still can't believe anyone paid for that monstrosity.

therckid

i'm not kidding about the big block or the 400 bro, these are for real, and my buddy has already decided to go with me to buy the other 454 he has also... so this is almost a done deal...

Because the entire system is easy enough for someone like me to mod. Some of the later stuff, especially the computers, makes my head spin. When my rustmaro finally rots its way back into the ground I may pick up a MAF or SD tpi platform and see what I can do to that. You know those induction systems, gotta try 'em all! Id like to buy a second thirdgen but I have nowhere to keep it.

I have that stashed away as well. Gotta wonder what they where thinking.

Shane, Id stay with a small block. A good 454 will eat your stock drivetrain and be really hard on the chassis. I trashed my origional drivetrain with an aneamic 250 some odd HP 350. I cant imagine what a 454 would do to it. But, maybe I can. There was a pic posted of someone who blew the drum apart in a 700 with a BBC, probably from slippage.

All right people, there's nothing to see here. Just move on and go about your business.

Shane, save these posts for the time when you can post your sales receipt and a picture of your purchase.
