Any cheap efficeint ways of tweaking a few extra hp out of the GM bastard motor? ;-x

Also, what kinda bigger 6's and/or 8's would bolt right up with the existing motor mounts, if any. For an 8 I can get a TH350 tranny, rebuilt, for $100, but whatever.

let me know....
thanks.

 

NOS.......

 

3.4l boogie swap

Home made cold air intake

Rollor rockers

Upgrade ignition system

Power pullys

Headers from CHC :hail:

Catback exhaust

DIY power chip

Oversized TB

TB bypass :sillylol:

 

Options are see above or just band aid it, sell it & buy a V-8
Accept your performance level, unless you want to do major engine swap followed by tranny upgrade.
Be realistic in your goal$ and fund$
PS No Turbos or superchargers here.
Just solid tune up knowledge or swaping knowledge.

 

If any engine was the GM bastard motor, it wouldn't be the 2.8. I'd have to say the 305 would be a better candidate, look at the power per cubic inch difference between it and our little motors

 

I'd be a tad inclined to agree with you on that, although the 2.8 seems to be a much hated motor by all but F-Body owners that I've seen. But take a look at the TBI 305...180 horses. And the old-school carbureted 305's? Factory power on those was PATHETIC..the H.0. carbed 305 made 180 horses!

 

305?
Try the
267 V-8
or
307 V-8
No one wants those!

 

267? How wimpy! And 307..that's just...odd.. I heard from someone that back in the day, Chevy took a 350 engine and destroked it and made a 302 but hardly made any of them..anyone know if there's any truth to that?

 

dont forget the 302 chevys too. not much power but man did they rev!

 

Not much power? ha-ha-haaaa-haa.

Check out the Oct 2002 issue of Hot Rod they put together a 500 HP V6 using some Vortech blower made for a V8, goes to show you what happens if you ask the question (what if?) and try it, lol
They did have the article on the website if you wanna check it out at hotrod.com

 

From what I remember they made all the HP but NO trq. And thats what matters.

 

Yeah..if it's a de-stroked engine that would explain that....stroke is what adds torque.. Explains why the 2.8 to 3.1 stroke job gets only 5 hp but like 15 or 20 ft lbs

Reminds me of that one hopped up Cadillac concept show car I saw..forget its name..made like 800 hp and around 400 ft lbs. :P Oh yeah, and it burned oil. Great job, Cadillac!

 

When it comes to acceleration I'll trade torque off for horsepower every day of the week.

See torque is just push. You can have 1,000 ft/lb of torque and go no where. Nada, no move, sitting at the lights and be putting all the torque in the world to the ground. But, unless you are moving, what good is it? Go ahead, sit your fat butt on the ground and see if anything moves. But (no pun intended) there is pressure being applied to the ground, IE: torque. And no motion.

Ahh, but you have to be moving with all that torque, eh? Well, if there is no motion, then there is no horsepower. Horsepower is the amount of energy over time.

Huh? Yep, horsepower is torque times time (ft/lb * RPM). In order to accelerate you need HP. It is that simple. Without HP you will not move. With HP you will accelerate. Push on a wall. Are you expending energy? Is the wall moving? You have torque, but no horsepower.

HP wins races.

The 307 came after the 327 (1969 model year/1970 model year across the board) was replaced as the Chevy standard V-8 engine.
This engine had torque & that's it.
NO hp potential, so never "work" on a 307.
267 was the "emission replacement" for a car model year or so. Maybe 1978-79
Real tiny pistons and that's about it. Wimpy.
The 302....
Thanks for no one knowing what that motor is.
It's a destroked 327 mill using a 283 crank.
Was "created" for the 5.0 litre limits of Trans Am in 1966.
This motor is so famous, I can't believe no one knows it.
Try this is the 1967-68-69 Z-28 motor.
"290" HP (right) & high revs were it trademark.
So was winning races.
Like Trans Am championships in 1968 & 1969!
1966 Trans Am championship was won by a Dodge Dart!
I believe 1967 was won by Mustang (Can you say Shelby)

 

They made a top of 501 hp and 437 lb-ft before blowing a head gasket, so overall it did cost some money to build it but it did come from a 6 banger!!, but like I say to each their own, I like v8 and v6, 6,s are more fun to play with nowadays until I can get a hold of a v12 and scream the dukes of hazard yeeeehaaawww while rocketing out of control in a bright orange pinto, sorry I always thought the idea of a day-glow orange pinto rodded out was funny I dunno maybe its me, LOL

 

don't forget the cam upgrade guys, that'll help out alot too. crane compucam is only $160!

 

Wanna talk about some power.. I saw in a magazine..forget which one..a friend pointed it out to me. A 3rd gen Camaro, yes that's right, a 3rd gen...with a 288 cid V-6, running 9 seconds.

 

Wouldn't have been one of those 3.8l factory turbo jobs would it?

RBob.

 

Couldn't say..don't remember.

 

I was just going to delete my post, this is why: The factory 3.8l turbo motors only came in Firebirds, you said Camaro. So couldn't have been factory. Could have been a transplant.

Then I did the math on the 288ci, that comes to 4.7l. So maybe it an overbored/stroked 4.3l 90deg V6 engine. Hmm, still that is one quick car.

Our 3.1l engines displace 191ci.

RBob.

 

Yeah..I remember the displacement numbers. That v6 is one cubic inch away from my friend's V8 65 Mustang..

 

3.4= 207 CID

 

yep, i know that guy, he has a 1986 sc with a 4.3 based busch motor. he runs the nmca/nsca super series in the hot street class. it's a nitrous motor. it has a holley dominator sitting atop a custom fabricated aluminum tunnel ram. very nice. car runs like 9.0's and 8.90's

 

the motor in the camaro is similar to this with the nitrous plumbing of course

might be Car Craft mag. for the 9-sec 84 V6 Camaro, do a Google search for "Joe Paterno Camaro".

 

stock for stock, your absolutley correct, but the 305 has more potential when the modding begins, its also cheaper to build

:nowputtingonmyflamretardantsuit:

 

Cam and roller rockers are always a good choice for increased horespower at moderate costs, especially if you can do the work yourself.

 

For the most part...once you put a cam in, you never stop paying for it..in gas.. But us redblooded Americans don't care about gas now, do we??!

 

It's a 2.8/3.1/3.4 V6, the extra consumption in gas is miniscule compared to that of a small block v8. I say the extra consumption is even out by being paid with horsepower.

 

Lol I agree... but nonetheless, you still never stop paying money for one...

 

I think that is one expense I could live with.

 

Ditto!
