How much power

How much power does it take roughly to move a 3400 lb car down the track in 10.5 seconds? (1/4 mile)

depends on how well you set it up and can drive.

650-700 is a good range.

Ah, so 618 would be lucky to run high 11's

No, again it how well everything is matched. 618 can go 10.5's

Good converter, good suspension setup, good gearing matched with proper tire height that maxes out right at the finish line, plus wide enough tires makes a world of difference and gets you going faster.

we run those numbers with a tad over 500 hp, but it aint 3400#'s either.


Why?

3140 with 625hp good suspension and a conveter thats to loose and the tranny's bout done. 10.50

i was hoping for atleast 10.90's with the cleveland but looks like that wont happen

You need to either quit messin with the smallbocks or get a lighter car........

If you've got test and tune night then go and see what you've got and what you might be leaving on the table. Never know what you've got till you open it up and see!

The cleveland like rpms they don't build alot of tq down low they where designed for trans am racing back in there day.Big stall or a stick so you gan get the Rs up on take off The clev will get you there with the right setup with it.

Well I am tearing down the engine because an intake valve wasn't sealing right. I'll probably deck the heads another .010 and gain a bit more compression probably clean the casting flash out of the intake as well. Maybe once I dial it in and all that in I'll put out around 625. I'll look into replacing all the glass and the freaking bumper, that things heavy Possibly the hood as well

An update I think I found some more power on teardown I checked the cam and found it 8* retarded

Matt I use alittle gas down in the port and look good around the valve and seat to see if I can see any leaking before I install the heads.The 8* off on the cam could be some of the problem getting it right may make for some more compression and better tune. Yes the hood is very heavy on them or was on my 72 and 73 model they are a mile long or look like it

I think mines about 7" long lol. I normally run gas down but it just looks like I had a bad valve from the get go. Should get my new one in Wednesday. And this time I'll bring in my video camera

I think I'll hit 650 soon
