Any been keeping up with that article in Chevy High perforamce? I have, sadly its for a TPI 305 car. Alot of the ideas are good, but I don't get where they think its an buget car. More like a buget for the middle aged man with money to spend and two kids. I'm 19 and I want ideas on what I can do to my 305 TBI. What i do know is Headers, True Dual Exhaust, Intake and I am thinking of a new cam. After the exhaust i don't understand enough to make desicisionson what to use or get.

I'm curious what some of you have done to spruce up your little 305. Nothing super big, but some ideas. I am not doing new heads so...

Those tips that they give are probably a great place to start. Who cares who it is geared towards? If they work, and are cheap mods, then do them, see how they work. Then you can worry about the headers and so on.

Forget about dual exhaust on these cars on the street. FORGET IT.

By the way, you can bolt on everything in the world, intake, cam, full exhaust system, high lift rocker arms, the works...but if you don't put money in the heads, you're never going to reach 2/3's of the potential. The heads is where the power comes from.

You see, every bolt on is about putting more air in and taking more air out. What does the air in and out have to run through? The HEADS!!!!

Most good engine builders will tell you that if you want to make decent power, your biggest dollar figure should be spent in the heads.

 

I resemble that remark. But, it's actually 3 kids, and who says we have money to spend?

Man, have you got a lot to learn in the next 25 years...

Agreed. Notice in the October issue they spent an additional $120 for a pocket port on their World 305 S/R Torquer heads. But, looking at the pics of the final product, they would have been better off telling about going out and getting an air compressor and die grinder, along with Standard Abrasives's deluxe head porting kit with their enclosed instructions, then showing what REALLY should be done to heads to get them right. Seeing those big ol' as-cast guides sticking out into the port are about enough to make you sick...!

I spent about $350 on a compressor, $12 on a die grinder (Harbor Freight), $35 on the porting kit, another $6 for more 40 grit rolls, and about 12 hours with the dust mask and ear muffs on. The end product is probably not up to RME standards, but not bad for a novice.

 

Here's what I've done to my 305.

Pulled the motor at about 120,000 miles
bored over .030
Comp Cams XE256
Edelbrock TES headers
Edelbrock Performer intake
3 inch exhaust from Y-pipe back
Holley Street Avenger 670 cfm
1/2 inch carb spacer
Vacuum advance HEI distributor with a recurve kit
160 degree stat.

Moves along ok for what it is but am now gathering parts for a 500+ hp 350 buildup

 

Its not a TPI, its an LG4 carb. And its still slow.

For a TBI, get yourself over to the TBI board and read. They have done things like headers, LT1 cam, open element intake, etc.

That was worth a chuckle. (But 25 years? maybe 15)

 

take a look at my mods in the sig.sure woke up the 305.

But with a little practice and a few more plunges with the die grinder, you can make your "weak" stock castings performa as well as most aftermarkets. If you spend a few more bucks on a welder, some nickel filler, and get really serious about moving port walls and locations, you can probably blow most aftermarket heads out of the water with "weak" stock castings. How do you think the "old farts" made power, back when there were no aftermarket heads? 800+HP 358s have been around for many years before most of these aftermarket companies even existed. Did we just forget everything we've learned?

Another hint: The Standard Abrasives kit is adequate, but a carbide spiral burr works a lot better and faster.

And if you think "middle-aged" guys are just rolling naked in the long-dead presidents, tell me what I missed, please. You probably have more disposable income that most of them (er, us?) and a whole lot more free time to experiment and toy with your engines.

Those 2.3 kids take a lot of time and cash investment, and tend to take precedence over a mere vehicle. Tempus fugit, Carpe dium, etcetera...

Oh...and Illegitimus non carborundum, and whatever other ancient wisdoms the Red Devil can interject.

Yet another reason not to have any. Cars are a hell of a lot more fun!

 

im managing a rebuild from a stolen and stripped 87 z workin for minimum wage with 2 month old boy, and its already holding a 27k l98 based 383 tpi with a 2400 stall 700r4 and 328 disc posi, along with a new front end and full suspension replacement (bilstein, trw, pst, etc.) oh and by te waay, i turned 20 on sept 2 this year. it can be done, just takes time and budgeting, and a fair bit of commitment.

 

No No No!! You are doing this all wrong!! The kids are just there to hand tools to you when your under the car!! Aren't they? Did I miss something here? Wait a minute............. what's a kid?

A "kid" is a device that most sensible Camaro owners eventually generate some of, to help ensure that there will be at least a few of our kind left to counter the Mustang and rice-boys in the future after we are gone.

I wrote a paper in college titled "Why Puppies are Better than Children".....I got an A!!

I think I missed the boat. While I produced a convincing arguement, I should have written, "Why Cars are Better Than Children"

Oh well, live and learn.

Cars may be better for awhile, but sometime around retirement age, you might have second thoughts. When you're in the asisted care facility, the car won't come to visit. Neither will puppies.

Vader, you forgot to mention the burette and flowbench. If you're moving port walls, you'd better have them available. Since aftermarket heads ARE available, you can spend less time with the diegrinder only on them, then spend every Saturday of the year hauling the horse around (which is what the kids seem to be interested in, not the horses we make in iron).

The CHP Camaro does seem slower than it should be with the mods they've done so far. Their stock and first few mods produced altitude-corrected times that are in the ballpark of my stock uncorrected times at 5800'.

Maybe they had their 300-lb editor sitting in the passenger seat...

57kid,

It was tongue in cheek. Absolutely pure silliness. I have two children. Their needs are wants are always met first (wants only to a point), and I get what ever is left over.

Actually, the reason I have a camaro is because I can fit my wife and two young daughters in it. In many ways I would prefer a motorcycle, and that's what I had before this camaro. I could go and do all of these fun things and see these great places, but without my family, it's just not as much fun at all.
