according to this, modern cylinder head can get 370cfm out of a SR head. that sounds pretty good to me

He says it ran 146 mph last year in the quarter.It was a 499 10 to 1 compression 700+ lift but less then 800 with the indy sr non max wedge in a 3300 lb dart. I think he was streching the truth some what do you guys think. Isn't that like 750hp to run that fast ib that car? From some of the post about big block it doesn't seem like thats what you guy get out of them.


In the mid 90s we had a 440-1 on a 499ci with about 12-1 static and net intake lift of .687 IIRC. A 3280# 69' Barracuda on SS springs and footbrake w/9" J converter went 145.80 in average ATCO air (maybe 1500ft).

Drove that car on the street as much, or more than any low 9sec N/A car in the country for 4 years, I'll bet.




Thats a good running street car, now with less head, less compresion and same weight do you think you could go faster? Thats what I was running late 90s and early 2000s with pump gas and a small block on spray. It was only 385 cuin with edelbrock rpm heads. Wish I never took that motor apart had a lot of fun with it driving all over the place.


Good question.....

Depends. We know alot more today than we knew in 94'.

Mr.Yuck if you are talking about Bill's blue demon it is a 499 with a 670 lift roller.He bought the motor out of my brothers full interior 30x10 tire 69 dart with mufflers and went 9.30's at 146.And 1967dart gt if you never see a street car with a big block run good you need to get out to different tracks more often.Not saying they are everywhere but there are some good running ones out there floating around.




Yes they are out there but very few just like small blocks. Its mopars in general not a lot of them. Next time I get down your way I will let you play with my nitrous machine, your brother to with his big block.




67 jeeesh such hate for BB, you know you could of had one that ran as good or better than that SB for 1/2 the price...lol




Another stupid pissing match. Yucko do you also go pick on the ricer kids in your spare time? It amazes me how much you toot your horn and only run 11.40s. In case you haven't noticed lately its not hard to make good power with small or big blocks. Its a really dumb argument especially when your car is slow.

hey viper put your sb in a 3900 lb car and come see me. I never said a sb can't run ashhat. Put that 340 junk in a 3800+ b-body thats driven to the track and home an you come see me Jack. BTW do you have a car that runs 11.30's? 11.39 SO FAR. I drive this car everywhere w/ kids in the back seat. If I want a 9 second car I can do it. If you notice I'm not "picking" on anybody. 67 has a nice fast car.. it's all fun. Don't take it or yourself to serious.

Mr Yucko,
My apologies! I thought you were turning another post into a sb vs. Bb argument. But it was the poster that started it this time. But in the past a lot of good topics you've hijacked with by stirring that pot.
And yes my pump gas eddie headed smallblock would have ran 11.40s in your car.

But I sold it to a guy that now runs 126mph in the 1/4 with it in all steel duster.
I am joining the big block crowd, but I still love those screamin smallblocks

My first question was on size with low deck and second question was how fast with indy sr's at 499". I have no beef with big blocks just some people think I do,just like bustin on the slow ones. Shoot I race with Guppy every month at cecil so I get to see his bada$$ big block all the time.

I think 499-500 is as bis as people go w/ the 400. And I'm guessing w/ a good driver and set-up it could run mid 9's in a full bodied car. Just as guess. RAYMOND here used to have a 67 Valiant way back when stroker kits were home made w/ 440 cranks and chevy rods. It ran 9.60's on the back bumper. They seem to be a good combo for the value.
67 Do you ever get down to Mason Dixon?

It seems the 4.25 kit would be popular and fit about as good as a 4.15 w standard rod journal. And fwiw I just ordered a eagle 4.15 crank with 2.2 journals that should fit even better. I really don't see performance being much different with any of these being 12 c.i.d. difference. The major horsepower is gonna be in the cylinder head.

I hope it runs that good for him, It would be a good race his big block to my small block. No I don't get out west that much but two years ago I was working in oakland md and raced there.
