Are newer cars just faster?

My valiant iron head 318 4 speed has been morphing into hotter builds for over 10 years. with open headers and 4.10 gears, all set up she makes 237 rwhp. Might go 14.70's. Basically a road car with cam,compression, and gears. Weighing say 3800lbs.

Not highway able.

Any newer car can whoop me. WRX, g6, Camaro's ,mustangs,lexus.....

Is it worth building a 350" with a RPM package from edelbrock for $3-4k in parts. When a $3000 used car , supercharged grand prix can smoke you.

Is that a serious question? This is "HotRodders.com" :-)

A 318 is okay, but rarely used for performance. You might want to step up to something bigger and nastier.

You are comparing apples to oranges.

You should compare your current performance to the way it ran before you made mods to determine if you are heading in the right direction. And compare your performance to other similar cars.

To try to judge your car against current iron will be a frustrating endeavor, IMO.

Anyway, what new GP- supercharged and all- can do a rear wheel burnout? Build a 1200 HP FWD car and it STILL will not do a wheelie! lol

All you are lacking is the HP and chassis stiffness and tuning to put that HP to the ground, to slay all those box stock new cars.

Anytime you have a heavy car with a small motor you are fighting an uphill battle (yes yes, I know about the new turbo cars). So put a bigger motor in there...383, 440.

350's can be built for a lot less than $4,000. Heck, I spent $1,800 on a rebuilt 454 Gen 6 roller long block, $36 for a mercruiser cam, , some cheap used headers, and my 4,500 lbs truck and dust my brothers stock WRX (2.5l turbo AWD). Granted he gets almost 30 mpg, and my rpm limits to my top speed to 120-130 mph. But I still drive my truck everyday, because I enjoy it, and have pride in building something, however humble it may be compared to big dollar builds. Everything, including the truck cost me 1/5th if not less of what his car cost him.

I've also seen what a drunk idiot driving a '72 camaro into the back of a 90's VW Golf at near 60 mph does. Camaro fine, VW in flames and no survivors. I like the weight, and additional steel larger old cars and full size trucks provide. As all that weight makes for a nice margin of the safety for my wife and son.

Seems cars are getting pretty fast. Can't figure out how their doing it with v6's . From the 70s to the 80's, and 90s was like a ladder. The 21st century is gonna be a blast. Grandmas' new buick GS is gonna wack a 454 chevelle with 4.10s and a holley.

We can still get the edge on the new cars. I used to love it at the high school drag races. I'd destroy kids whose parents bought them the latest and greatest. They just put fart can mufflers and cold air intakes on them and left it at that.

I was driving an old 76 Cutlass that cost me $200 with a blown motor and another $500 for the donor engine (455 from an old Riviera) plus a summer of hard work learning how to put it all together. It was pretty darn satisfying to see how hard work bridged the gap between the $1000 car I was driving and the $15000 car mom and dad bought them.

Sorry to break this to you, but only 14.70s and "not highway able"???

Sorry, but you're doing something wrong.

I will say, however, that forced induction, modern cylinder head design, and modern computer controls, along with lighter vehicles, DOES make for faster and quicker cars. Think about it - the BASE V6 in the new Mustang makes 305 HP NET and gets 31 MPG highway. That's pretty darn impressive.

Wrong, My 323 has indy 's Aeroheads with modern bean chamber, porting, 1.88/1.60's in 318LA heads, single plane Streetmaster intake, MP pistons, purlpe shaft cam, summit racing headers, Holley carb, 4.10's, HEI , What is to mess up? The gears kill it with no overdrive.

Old pic on start stand.



A 2000 GTP, or even a new Taurus family car can really go fast.

Are they the p/n 318 heads?

Something to consider: All LA engines will easily take a 4" arm...

Efficiency. The Ottoman is a hundred fifty year old design, we were without computers, modern design induction, the research to make these engines more efficient, with that comes the horsepower, changing a drop of fuel from a firecracker to a bomb is bound to make a difference. They weren't making these numbers with Indy cars 30 years ago.

The new cars are very impressive. My friend has a new camaro SS and with a cam, cold air intake, headers, and a tune it is making 500 rwhp and this is through the stock mufflers.

Heres another guy I know with a 06 Vette making 459 rwhp with a cam, headers and exhaust.

Car Craft had a challenge in the last issue where guys were competing with new engines in old cars. Needless to say most of them were LS powered but alot of them were mild builds.

I saw that engine swap drag article, too. Small turnout this time (first year) but if it catches on- look out. No idea what the rules are, I'd have thought there would've been a lot of Mod motor swaps, new Hemi's, etc. but like you said- mostly LS swaps this time.

The LS engine is pretty amazing, though. The mag did a couple tests w/a 6.0L/364 cid engine from a junk yard a while back. I believe it was the LQ4, w/9.4:1 CR (the LQ9 has 10.1:1 CR):

Stock engine
750 carb
GMPP open plenum intake
stock cam
1-3/4 headers
made 425 HP @ 5600 and 439 TQ @ 4400. It made 406 TQ @ 2200.

With the GM HOT cam, it made 483 HP @ 6000 and 450 TQ @ 5000. It made 399 TQ @ 2200.

HOT cam specs (from GM):

The duration at lash point in degrees (intake/exhaust) is 279/287; duration at .050" tappet lift (intake/exhaust) is 218/228; and maximum lift with 1.6 rocker ratio (intake/exhaust) is 525/525. Valve lash is zero/zero and lobe centerline is 112 degrees.



Pretty impressive.

Driven a factory loaded Shelby GT500 Mustang lately? You dial in the desired performance sitting at the light and hang on. Not sure of the 1/4 times on the 2010 version, but the 2008 was 126.X with a novice behind the wheel. Same novice says his 2010 is much faster, but don't think he has taken it to the limit yet. You are talking about a 130s 1/4 car that you can pack the trunk and back seat and take your babe on a nice vacation get-a-way in air conditioned comfort and high 20s fuel economy. Now I don't call this hot rodding, but most of our hotrods don't have a chance against this factory beast.

Didn't the 2010 gt500 run like mid 12's on motor-trend? With a few bolt-ons you could maybe see some,what mid or low 11's? But look at the price tag+tax+tittle plus the mods(which are not cheap) to get that ride. Invest that amount in any old heavy chevy. You'll be began for 10 lengths. That 35k that you spend on that bolt-on gt500 would never see 35k invested in an old school anything,lol. Or is that a fair comparison?
