ballpark horsepower guess of a 468 bbc
 

I just picked up a 468 shortblock that is 12.5:1... I have steel LS6 heads for it with a .718 roller and a Super Victor with a 1050 dominator...

I am just trying to get horsepower guesses...

thanks for your input...

655

heads flow ? the cam @ 50

Unfortunatly I dont know the flow numbers, they are ported a little. The duration @ 50 is 278... This is my first ever big block, I am setting this on my dragster, I was just wondering what horsepower it might be and what it might run at 1900 pounds....

thank you guys for help..

Should be a 5.30-5.40 car I'd think mid 600 HP

I would be very happy with that! somewhere around 8.40-8.50 in the 1/4?

David have you used a shorty glide in which the gear set was resplined to make it shorter? My shorty glide is a stock case with 1.76 stock gears that have been re-splined... It has the good high gear hub and clutches with a tci pro tree brake. Do you think it will be fine behind this motor? It worked perfect behind the 406 but I have heard mixed opinions on it behind the bbc...

thanks

These are my numbers below. My engine is approx. 700hp and the car weights 1850lbs. with me in it. I'm hoping to run a high 7 this year 8)

I've never had one resplined but I do think you'll be fine, I ran 1/76 stock gears behind my small blocks going 5.0's/8.0 @ 1900lbs and never had a problem. The big block wont make a ton of HP and will be fine I think when you start getting closer to the 800hp mark is when you'd need to start thinking of a 1.80 straight cut.
