Thread: Your Thoughts On This Engine In Street-Use?

over 700 hp in a daily driver ...............why. thats gotta be a whole lotta fun in the traffic. i have a friend with a 550hp viper and its downright scary on wet surfaces and trust me these cars are glue on dry road...have fun

AND.....please send me a picture of the tree ya wrap it around.

1981 el camino 514 - 9'' ford dif. 400 trans. 454- 671 blower, 7.5 pistons, mild cam and everything else stock, 2- 650 carbs, had chokes working on carb for cold starts. drove it daily and to work for about 4 yrs. run pump gas, had some problems on a real hot day in town wonting to run hot. all it was good for was profiling, you couldnt kick the boost in because of the gas, i jeted the carb. for the st., couldnt run it wide open anyway. it had so much power, all it would do is spin . i had all of the heating, timing, braking things and hookup problems that goes along with something that extreme. he can do what he said but i dont think he would be willing to do what he would have to, to keep it running, its going to get old fast. ive had 2 el caminos and a 70 chev. conv. with motors close to what he was talking about. and yes it was dangerous to drive, no i didnt drive out of town with that gear. it was the only one like it in va.

In fairness, I will not say, 'Oh Boy, to Jlells01 yet', but 779 horse power on the street? Alright, I admit it's possible, anything is possible if youv'e got a lot of money, but if we divide 770 hp by 459 cu3 we are getting a cubic ratio of 1.7, now that would be getting a little bit iffy on stock engine parts. One thing about supercharging especially roots positive displacement blowers as well as generating hp, generate HEAT, because the rotors beat the (expletive) out of the air, this therefore heats up the intake charge. Possibly, as a lot of people know, when you are making full noise with a supercharged engine you keep one eye on the temp. guage and one eye on the road and one eye on the speedo. because all that heat has got to go somewhere - you better have a really good cooling system, if you want to stay out of trouble (detonation). Last thing, when you are trying to make 770 hp you won't be talking mile per gallon but gallons to the mile. So even if it had unlimited road space it would be a very expensive thing to run.
I would say being more realistic, is run the 454 with 1 hp per cubic inch and you'll still find it quite a handful. At least you'll be giving your cooling system a decent chance of doing its job. Personally. and this is just me, I would say the maximum hp you could run on the street is 400 at the flywheel and 325 at the rear wheels. If you really want to have fun on the street, concentrate on torque. Thats the real secret of street supercharging, blowers generate lots of low down seat of the pants torque and you can really feel that.

i dont belive he would have all that horse power anyway, in my case all i had was a stock 454 with a blower on it, so up untill you kick the blower in it was factory h. p. 200 h.p. ? if you put a blower on a stock motor nothing changes untill you kick the blower in and with a 514 gear around town there was no reason to run the motor WOT anyway. you'll are right about the heat and detonation and i have the head gaskets and piston to prove it and it took a lot of time and money but i ran a 454 blown motor with pump gas on the st. everday for about 15 yrs. you had to know what you could do or not do . under no condition could you run the motor WOT because of the heat and detonation. you could do most anything you wonted in low gear and some stuff in second gear but where you had to watch yourself was in high gear, so it made for a bad ass car from stop light to stop light. from 1982 to 1994 one of these cars was on the st. every day.except for the wagon just drove on sat. and sun.

Hey guys, the post was started last November. Don't think the original poster is even around anymore.....................

He's probably having too much fun cruising his daily driver. Or he flunked out of college and doesn't have acess to the computer.

All I can say is that if your driving that thing every day. GOOD LUCK. You got balls man. Anyone that calls that a daily driver likes to burn rubber. Have Fun in the rain

700 hp is very streetable, you just have to have the right sized vehicle.
Kenworth?
