Re: SS396 Vette Idea (norvalwilhelm)
norval and Fevre: My apologies on my previous post. Thought this guy already had a 4-bolt 396. Didn't mean to spout off like that.

That's a REAL general statement and is NOT always valid. There's a hell of a lot more that goes into a winning drag car than just large cubic inches.
I can't count the number of big block engines I've seen blown away by a high-revving mouse motor. I've seen a TON of big blocks get embarrassed by Boss 302 and Z-28's with 302 cubic inch engines. And the drag classes are based on more than just cubic inch. Weight of the vehicle is also a factor that is measured on a scale. Better dig deeper into your example before laying it out as proof :nono:

So what's the point of having 800 horsepower and not being able to win a race??? I couldn't see walking around showing time slips that were in the high 16s but saying "yeah...but I got EIGHT HUNDRED HORSEPOWER."
Not unless you want to be the laughing stock of the drag strip :crazy:

Re: SS396 Vette Idea (Dep)
We are talking engines here not car set ups. Put that 800 horses in a semi and it will get beat by 100 horse motorcycle everytime. It is way to complex to factor in every detail when it comes to a quater mile race. I was refering to the potential power output of 2 engines of similar build, one having more CI than the other. I used the NHRA reference to illustrate that those cars are set up pretty close to each other and the bigger CI engines usually win. Throw 2 engines on a dyno and you are looking at pure power. The engine with more CI has the potential to make more power, of course set up is a major factor.

Re: SS396 Vette Idea (Fevre)
it sounds like he is building a motor to stcok specs though... i wouldnt think a 454 would have that much more than a 396, but thinking about it in the 1hp per CU IN, it does sound right. :yesnod:

Again...pure horsepower is meaningless unless it can be hooked up to the rear tires. Comparing semis and motorcylces is apples and oranges AGAIN.
"I was refering to the potential power output of 2 engines of similar build"
Okay...let's take those parameters. Two single four barrel engines.
You take your big block and I'll take a NASCAR small block. Let me know when you reach 750-800 horsepower with a single four barrel and then we'll talk some more. And remember...on gasoline with NO nitrous or turbo or blowers or any other special mods.

Re: SS396 Vette Idea ('79ProwlerOrange)
Don't lock yourself into that "one horsepower per cubic inch" idea. That was a goal that was reached back in the early 60's with the 283/283 horsepower Vette. It is possible to more than double that amount. 350cu in/750-800 horsepower is reachable if you have deep enough pockets.
And that horsepower level is on gas WITHOUT any exotic induction. Single four barrel Holley carb.
