Why? We used to run 452 inches with unported heads and the old .750 roller and didn't have to spin them 7500 to make power. But I doubt the motor is the issue with this car.

If and I repeat IF the 119 is not a typo, at 2550 pounds, this thing makes 650ish on HP, which is not tough for an alum headed 470 if it has decent parts. That said, you should be able to kick it off the line and make it 60ft harder than it is, even with 4.10s and a 1.76 glide. I think the converter is way out in left field


Yep, and they would go 6.50's....

Check the video where he's starting it, a Lot of drag at first, timing, compression or bad starter? Never could see the tach during first gear. He needs to put in low, engage trans brake then floor it to see how high that converter goes.
At 119 mph with that tire and 4.10 gear he's only turning 5040 rpm, drive shaft speed, who knows what the engines turning.

Something is goofy and that didn't look like no 119 run to me and when I paused the vid I thought I saw a faint 105-109 mph......... shruggy

So that would mean even less rpm at the stripe.

Time slip people should be posting Time Slips if there isn't a time slip it didn't happen.. the increments are very important

I agree and it seems odd he wouldn't want to help figure out what's REALLY happening so I`m done here.............

We might not be telling him what he wants to hear.
Birdcatcher, there are some very smart guys on here, only trying to help you. No one is trying to put you down, they want to see this car run good, just like you do.

My guess is he's just doing the Norwalk thing right now.
In an earlier post he said he'd post some slips from there, so we'll just wait and see what they look like.

I have had dealings with him in the past and he is a straight shooter.. but Time Slips and engine combination.. all that stuff is very very important I run a Glide behind a small block leaves like a rape ape so if it will run 119 it's got the ability to leave real hard

so here is my weekend in a nutshell. I got there friday at 10:00 a.m and missed #1 qualifying pass. I seen a good racer friend who loaned me a 1150 dominator to try. So on my first pass friday afternoon it went 10.66 but still bogged real bad. So I put my 1050 carb back on Saturday morning and it went 10.41. We only got 1 time run. Went up for round one and went to leave, the car bogged and died without moving out of the beams. Other guy redlighted so I won that round. Went back up for round two and went red. I hesitated at first about running it out thats why it went a 10.50. I ran a qualifying pass on sunday and went .004 red in round one. I put it away and brought it home in one piece. So now I have a cracked header tube and also a small stress crack near the shock tower.

That's not a bad weekend. It's still running and looked pretty consistent for as wide a weather swing as it saw.

I had a really long weekend. I helped 2 other people run their cars also, towing up to the lanes, cooling down, getting the dew off the windows. We got done with saturday night race at 1:00 a.m sunday morning. Birdtracker

so first things first, I am going back to square one. Compression test, then recheck cam timing. I am going after why it has a bog. I will let you know what I find. Birdtracker
