65 327/365 vs. 427/390

Maybe you haven't been paying close attention. The discussion doesn't include a '65 396 Corvette. Not the same animal as a 390/427.
But since you brought it up, I remember blowing of all three of the '65 396 Corvettes I raced in '65 with a stock 327/375 (small block) in a '65 Chevy II.
Size does matter, doesn't it? Go ahead, take your pill.

Street Stories;-)
My 67 427 ran a 13.84 on street tires at Conroe in late 68. That day there was a 427 Fairlane with "Wickersham Ford A Stock World record holder" painted on the door. He ran 12.xx second quarter mile times on 7" slicks.
The following Monday evening, I happened to run into the same car on Kirby Drive at Bissonet in Houston. The driver was the same middle aged gentleman but with a blond with a beehive in the pasanger seat. He looked over, motioned for a race, and reved his engine, so on the green we went. My car hooked....his didn't. We only went 2 gears, but I got him 2 car lengths in those 2 gears:-)

I still have the timing slip from Muncie, Ind. dragway when I ran my pure stock 250 hp, 327 , 62. I was running 1968 Corvette rally wheels and the F70 redline tires on it. My time was 13.97 in the quarter. This was in 1974.

NEVER BEEN PAST 6000 RPM. That's where the 30-30 is at home. Take it to 7000-7200 and then rip off a quick shift. The tack falls back to 5400 RPM, right in the sweet spot.

You're not paying attention again. Take another pill. Here's what I said:
"with a stock 327/375 (small block) in a '65 Chevy II."
It would run mid 12's @ 110-112 mph.
I still have it. Would you like to try it out?

The 365 hp vs 390 hp Saga Continues
It's sure a lot of fun to argue about which is better but let's face it. The bottom line is that the 427 is stronger and slightly faster. After all, GM didn't rate it higher at 390 hp and copious amounts of torque for nothing. Let's go back thirty tears ago when Bo Laws was running his 66 390. He was turning 11.60's e.t's when he won at the Winter Nationals in Pomona. That was a stock 427 Corvette. The only allowance by NHRA was the use of any flat tappet cam and headers.
The best e.t's that I saw with any stock drag prepared 365 hp Corvette was in the 12.40's. Pretty damn good if you ask me. Like I said before, it's very difficult to create parity because we're comparing apples and oranges but in spite of the 427's dominance my opinion is that the small block is a more durable engine that has withstood the sands of time.

If Laws had a 390 HP 427, Well he couldn`t then install a solid cam where a hydraulic was as it would no longer be stock for a hydraulic cammed class. Thats cheating and automatic disqualification. Right?.
And NHRA does tear engines down to make sure they are stock. And Cams are especially scrutinized;

"'ppears to me, you're the one comparing apples to oranges. This discussion was about stock cars, presumably showroom stock. Stock tires, exhaust, etc. Not NHRA stock. Bo Laws car was far, far from factory stock. His 390 "stock" Corvette would blow any factory stock 425 hp Corvette of the period in the weeds.
Then again, you don't have to have an IQ much above room temperature to understand 100 more cubic inches means at least 100 more horsepower in a race engine.

My question to you would be, "do you have ANY first hand experience about what went on in 1965"? What were you doing back then while I was out tearing up the road and chasing girls? Do you read lots of old books?

Wow
You just can't beat a BBC, 4-speed and low gears for the next best thing to good sex! Especially when the first time for both was when you were a teenager!

It must be about time to shelve this one, isn't it? For one thing, there probably isn't a stock 327/365 or 427/390 out there that someone is willing to run against in a real race situation so all of this is just wind. What someone ran in the 60's and 70's doesn't mean much on paper. I could tell you my car ran 13:20 in the quarter and swaer it was gospel with no way to prove it. Of course, my never did that, it was just an example of what you can put on paper and never prove. Some guys will drag out their old time slips and say I told you so. Well, that is probably BS also. Even back then, when these cars were running in the stock classes, none of them were really stock from the factory. They all had mods to them, they may have been minor, but they had them. Headers, shifters, etc., what ever. All of these mods were made to make the cars go faster, so you cannot call them factory stock. So without creating bad feelings here, lets just let it die a slow death. JMT

1238 people must have thought it was interesting. I've enjoyed it. Sure it's all wind until you drop the clutch. So what?:
You have an option.

My vote is for the 327x365hp.....
Why? Well maybe it's because being a loyal 365hp owner and simply me stickin with what I brung, and until one of you BB owners lets me wet myself in your front seat, dumpin the clutch at the start of a quarter mile test run, that's my story and I'm sticken to it.
Now....who's steppin up and providing me some adult sized depends?
BTW-I will be leaning more towards the 427 once I get me one.

look back at my posts about the 67 427 that ran.
then get a diaper and rub the dust off your prized paperweight.
I see these cars run all the time. mine engine is 'breathed on', many others I race with are not.

I was wondering how much difference running on today's 93 octane makes with these two motors? The 390hp has a lower compression at 10.25:1, the 365 was 11:1.
Anybody ever run a stocker on a dyno?

I seen a black 65 chevy 11 with that same setup at a Daryl Starbird show here in Tulsa. Cool as Hell. It was awesome looking. Im sure it was not factory but it should have been.

''back in the day'', we raced road courses all over the east coast...small block vettes were B/P and big blocks were A/P...both classes tracked/raced at the same time...first overall was always a BBC, but many B/P's finished ahead of ''slower'' A/P vettes...those BBC's had solid cams, open headers, etc that gave them advantages that a 390/street BBC would not have, the B/P's were much closer to a ''stock'' 327 -- i'd bet on the mouse.
having owned several examples of each, i CAN say that the BBC cars are a ''you ain't lived till'' thrill, but a free-reving SBC with ANY solid cam is FUN.
