Have to agree with iroc22 again.

 

The thing is I have and I know what I am talking about. Sure most of the imports finding their way into our country are OHC, but the thing is domestics have been in this game longer than anyone else (except Mercedes-Benz) and they know whats going to work. I know two examples of OHV engines in today's world. Top Fuel dragsters and they make 5000ft/lbs of torque and 7000 hp with their technologically inferior engines. Oh oh and wait I know another example; GM made them in the eighties and stock they can do 8's according to their owners. But what were they called again.....oh yeah Grand Nationals.

 

Oh yeah true, but it wasnt a Chevy engine by any means. It was designed by Lotus and assembled by Mercury Marine. It definitely was an awesome engine, but GM really didn't like it that much, and the aftermarket was crappy.

 

I'm not saying that the pushrod motor is a piece of junk
the the ohc would allow you to run a more agressive cam setup without having valve float, less loss due to friction and the ability to rev up higher. also with less hardware you are going to have less slop and so you are going to make for better valve timing which again will produce more power

the biggest problems with a OHC is cost, timing belts need replaced more often.

you keep saying that the pushrod is better can you say why though?

sorry not trying to be an *** but if you say it is so I'm not just going to bow down and take that I would like to see why.
I have given reasons as for my point of view on this
can you disprove my reasoning?
sure you might be able to give cars that run a pushrod motor but still I have yet to hear why it works like that


and also please don't get so touchy just b/c I do not agree with you. come on if we are all on the same board here. I just want to learn and if you can prove me wrong then that will be good b/c I would learn something new. but give reasons not just say it and expect me to take it as fact

 

I beat the 00 GT convertible from a dead stop to about 120mph with my 305. i was pulling ahead of him (slowely) on every gear. My girlfriend was my passanger so she witnessed it. There was a passanger in the GT too.

When i hit the first gear my tires span a bit but when they hooked I pulled away on him at least 3/4 car's lenght. Thanks *** to TPI's monstrous TQ.

My car was seating for few hours so the negine was cool when we raced.

PS. And it was a GT not a V6.

My mods are below.

 

Yes and what you say is true, and you will produce more power, but that was never my arguement, my statement was that OHV produces a much BROADER torque curve, which will benefit you when you are drag racing.



How many times do I have to repeat myself: IT DELIVERS A MUCH BROADER TORQUE CURVE.



Hmmm lets see: IT DELIVERS A MUCH BROADER TORQUE CURVE.

I'm not touchy, you're the one that started this little arguement by not agreeing with ME in the first place. The thing is I agree with you that the OHC design allows for a lot more agressive cam profile with faster ramp speeds which allows it to make more HP and a higher redline. However, the OHV design gives you a much broader torque curve. Here's a quote from a SLP engineer commenting on the LS1:
"A little known thing about the over head valve configuration, especially with V8s, is that it gives you a much broader torque curve than an engine with an over head cam. This broader torque curve allows for faster acceleration and an overall easier engine to drive."

 

This is silly but I'll reply anyway.

There's fast F-bodies, there's slow F-bodies

There's fast Mustangs, there's slow Mustangs.

GM used to sell alot of 3rd gens, they don't sell many 4th gens

Ford sells alot of Mustangs but there must have been times when they weren't a desireable car (late '70's maybe?)

Why's GM cancelling the 4th gen? If it's such an impressive car they'd make it meet crash standards. Ford cancelled the Escort something or other and 4 other models?

GM will build another king of the road muscle car (besides the 'Vette) someday, The Mustang will falter someday. And what about Mopar? You all know something will pop up from them one of these days (Charger R/T??)

We are all loyal to what we have, I'm sure there's somebody who feels like king of the road in their Hyundai Accent, after all, he raced a LeCar and beat it.

And whoever said a STOCK L98 car is fast is on crack. I own one and it IS NOT fast. Fast is a perception though. Fast compared to what? A Boeing 747 is FAST, it is not QUICK though.

Last thing....about DOHC....I heard that in 1994 that a DOHC Dodge Neon with 5spd was the 2nd fastet car 0-60 only thing faster was the Viper (HAHA)

 

hehe

not just going to sit there and agree with everyone now
come on if all just sat here and said ok yeah thats the way it is and never got into why would we ever really get anywhere?


and as for it giving a wider powerband I am curious as to HOW it will give you a wider powerband. not going to say that it doesn't give a wider powerband but curious as to how

guess a lot of it also depends on the motor setup as well
lot of the car makers I talk about seem to try to make motors that rev while most of the domestic market likes motors that make power a lot lower in the rpm range

having a big powerband yes I agree that is and helps a lot though most of the car makers that are using a OHC will gear the car to fit that powerband.

all depends on your opinion on how you wish to set the car up I guess

my taste is in high rev motors as long as they have the gearing to match the powerband

but again that is all opinion

 

just for the record, L98 motors arent slow. My stock L98 Vette broke into the 13s (13.9 at 98mph), and that was with an automatic! Now compared to a LS1 Vette? Then yes, my L98 is slow (got killed by a stock LS1 with only a torque converter... he ran a 12.6). Now, compared to most other cars on the road, an L98 will usually hold its own. Because of the long runner design, and low rpm power, L98s are very good from stoplight to stoplight. As a reply to the topic, if the Mustang is an auto, the L98 will have a good chance if he can get traction. However, if the Mustang is a manual, and the driver is exceptionally good at shifting, then no, the L98 will lose. Food for thought : how many people are actually good enough to get a stock 5 speed GT into the mid 13s? Not many, although we all would like to think we are that good at driving, the fact is it doesnt happen very often. Just like very few people can get their stock LS1 Fbodies into the 12s, even though some people have done it, the average person cannot.

 

I like it that when comparing times for the cars, the Camaro gets its best time, whereas the mustang gets its worst time. Another thing is that most of the guys who put down the stang drive slow 305s and claim to have beaten new GTs. Give me a break, I have seen tons of races between Fox body stangs and 305s and the only 305 I've seen win was a supercharged one that went 13.2s. You are saying that they only go 14.7s, when my dads 1991 LX 5.0 with K&N, cat back, pulleys, and tires wnt 13.6. So those parts on a 225hp car make it 1 second faster than a 260hp car. RIGHT!!! And for all of you that will claim the mustangs don't run 13s bone stock, how come a friend of mine in his 87 couoe is going 12.8s with K&N, Full exhaust, pulleys, and bigs and littles, and went 13.69 BONE STOCK. I'm not saying the mustangs faster I'm just saying the Fbody IS NOT the best car ever made.

 

Where did that come from??

 

I think i'm going to go soup up my lawn mower and go race some mustangs with it. Maybe I can even get it to be faster than an F-body
