how about all three lol.

90RS305

Stock LO3 I think I still have the fastest pass at 15.3, but overall I've been spanked by some of the guys here...

Who's the maniac here with the engine in a van


That thing is fast

camaroracer1992

on motor my best was 15.299 in teh qtr at 89
on nitrous my best was 13.18@103.4


keep in mind stock heads and cam in my car when it was a 305

Dewey316

I hate you guys with traction.


N/A -- 14.5 @ 94
Nitrous -- 13.3 @ 106

Is there anybody in the low 11s?

Dewey316

If anyone would be close, it would be this.

Fast355

iTrader: (2)

I don't know if that was a compliment or sarcasim.

Fast for its size, weight, and engine. You have to consider it has the Aerodynamics of a Brick and weighs 5,300 lbs. In F-body terms I would be solidly in the 13s in your MUCH LIGHTER more aerodynamic cars.

The old 355 did this with a 3.08 gear.

60' = 2.55s
1/8 ET= 9.85
1/8 MPH= 77
1/4 ET= 15.6s
1/4 MPH 87.6

The new 312 has produced this with a 3.73 gear.

60'=2.19
1/8 ET= 9.89
1/8 MPH=69.08
On a seperate 1/4 mile run
1/4 ET=15.82
1/4 MPH=88.65

I vote for compliment. For some reason I think your van is the neatest thing on the TBI board right now. Who else would work that hard on an '83 land yatch and have such great success that we can all learn from.

Fast355

iTrader: (2)

Thanks, though I really haven't worked that hard. Just fixed things when they broke and upgraded as I went. I just used my knowledge of the internal combustion engine and the rest of the powertrain. You will have plenty of power, if you can get rid of the restrictions.
Whats funny alot of the guys over on Fullsizechevy.com still don't want to get into the EPROM. They told me I had a Hard-on for my Chips. LOL.

I think on mine the final piece of the puzzle will be Rbob's Ultimate TBI code. I would not have been able to accomplish what I have done, without his help. Be it the articles he has written to the help he has provided.

If you had a van to drive that was in good shape and had to make the trips I make, you would understand. It is quick, cruises well, and is very comfortable to drive. It handles everything I have to carry and can tow just about anything I need. It suits my needs well. I am still working toward getting a F-body, but just don't have the funds for it right now. It just would not fill the role I need it to do.

If I were you, I would take it as a compliment, regardless of how it was intended.

no passing mention?

THE ANTI CROSSFIRE

Fast355

iTrader: (2)

I personally like the ANTI CROSSFIRE. You have done great things with that car. I find it kinda weird that we are DIEHARD TBI guys. We could have swapped to a carb and just been done with it. Instead we are faced with how to get 224*+ @ .050 of camshaft to run in a TBI application.

BMonteSS- swapped to TBI and made his car run, then fraged his engine and then the replacement. (I feel your pain).

Then we cannot forget Dimented's MASS AIR TBI car. Lots of engineering went into it. Then he was able to do a heads and cam swap with only some tweaks in the chip. Good job.

VA454SS-failed to post his track numbers, but IIRC his 454SS is TBI and from his numbers on other posts, it SCREAMs.

Then we have Jon's Vortec 350 TBI beast. I am sure he is out showing up TPI and LT1 cars as we speak now. His 8746 Hack has been nearly priceless for my TBI ventures.

Finally I think the biggest news once again goes to R-Bob.

I know there are several other fast TBI engines on this board as well. If I am forgetting anyone let me know.

Dewey316

While I think mine is pretty impressive for what it is. I'm working on a new set of mods, to really make peoples head turn when they realise it is still a TBI 305.

BTW, if anyone has a 454 TBI unit, and some big(er) injectors, that would part with for fairly cheap, please let me know. I KNOW After this next round of work, I will be maxing out my current setup.

That was a compliment. Anyone who can hotrod their 305 to that extent and still run it in a van, has my admiration for sure.

Fast355

iTrader: (2)

I am going to assume you are going with better flowing heads. 081s or Vortecs or Neither?

If it were me I would go with a set of Dart Iron Eagles 180ish CC ports, a Holley Projection intake, a bored SBC TBI or a 454 unit, and the bigger injectors. But thats just me.

I actually test fitted a pair of Dart Iron Eagle 230 CC heads with 2.08" & 1.60" valves on a .030" over 305 with a Comp Extreme 274. Stuck the clay on the piston. Installed the pushrods spun the engine over. Measured the clay. Guess what, they fit, and clear by a substantial margin. The valves would be shrouded badly, but they still fit. To help get rid of this problem the block could be massaged there (think of the Hot Rod Junkyard 318 Dodge Build). You can get 2.02 & 1.60s in there pretty easily.

vorgath- thanks for the compliment, sorry I doubted you.

Dewey316

I'm tossing some ported 416's on. Since I already have the Wieand single plane, I think I'll stick with that. If I have the money, I may step up a bit cam wise, I am really thinking the LPE 211 or 220 would be a good fit for my motor, but I don't know if I'll have the money to justify buying another cam.

DM91RS

What's the spec's on the LPE cams John?

I can't get the LPE site to work right.

DM

Dewey316

LPE 211 -- 211/219 duration @ .050 .530"/.560" with 1.6 rocker

LPE 220 -- 215/220 duration @ .050 .534"/.544" with 1.6 rocker

90RS305

I think cam specs are the one thing I do not and will never understand, lol. I know what it all means, I just don't like doing the "connect brain" thing to piece it all together. But if Dewey is gonna buy it, it must be something good

Fast355

The RIGHT cam will make or break you. I personally like a select few GM camshafts as well as the Comp Cams Xtreme 4x4 roller grinds. I have personally run the X4270HR cam in my little brother's Tahoe (has a pair of ported 193s on it, my third set). It pulls strong to 6,000 rpm with this cam and is still a relatively mild cam. Here are the specs.

RPM Band = 1,500-5,500
Advertised Duration = 280/284
.050" Duration = 220/224
Lobe Seperation = 111*
Lift w/ 1.5 rocker = .474/.474"

Dewey316

I think they would be a good fit for my motor, I don't know that I would suggest everyone go out and get those cams. It would probably be too much for a car that doesn't have intake/heads, and someone who will do a lot of tuning on it.

BTW, you don't need to know everything about the cams. I suggest knowing enough to understand what the numbers mean, and knowing enough to talk about it. But, this is what cam manufuctures are paid to do, they will help you pick a cam for your car, just talk to them, call up any of the cam manufactures, they will be more than happy to help you pick a cam out.

DM91RS

John thanks for the cam specs. I'm interested in another cam choice for a 350 myself. I have a ZZ4 cam to install but now that the UTBI is coming out tuning a larger cam looks to be more doable.

DM91RS

Posting this to mention some people that are up there with their engines with tbi. (Since you did ask for Fastest TBI car's)

Ben73...............................12.48 111.6mph 383

Dominic Sorresso..............13.3 @102mph 350

Granted they are both crossfires but they are still TBI's. And Ben also had a single 4bbl unit running his without the crossfire intake IIRC

Dominic Sorresso

DM,

Thanks for the mention. And using Xfire manifold as well. Might have gone quicker if it wasn't for the lousy LCD tach and the fuel cutoff.

What did the other silver car run?

Dominic Sorresso

DM,

That was an 88 Anniversary Vette. I was there with the Fox Valley Corvette Club and the Chicago Corvette Club. We were bracket racing at that point. He ran a 15.03. on a 14.95 dial. I lost because my R/T was slower than his. Don't know why he ran so slow.

There's not a TBI "Fastest Car List"?
