Car is a 71 dart with a race weight of 3250 with driver.
powerglide tranny with 1.76 gear
4.86 rear gear
29.5 X 9 MT slicks

need more info, just let me know.

curious to see what you guys think the HP numbers will be, and what the 1/8th mile ET will be. hoping for 6.80's on gas, before switching to alcohol. thanks.
 
Depending on your converter performance, hook, and other variables, i'll say......

Just either side of 7.00 @ 97-100......since it sounds like the first passes with this combo.

P.S. The gear/tire dia looks pretty good. Should cross the stripe in the 5500/5700 range. You may be leaving a little on the table with the 1 5/8" primaries though?

P.S.S. Removed my above numbers...... I must not have had enough coffee when I typed them....lol.
 
What's the Separation angle on that cam though (LSA)? I assumed it was cut on a 106/107, but you know what (***)uming makes me......:mrgreen:.

7.50 is my guess. what's with the 111 centerline and the headers? those two things leave a lot on the table.

no offense bob, but my 440 powered 67 belvedere has been 7.44 with heavy 10.1 pistons that are a mile in the hole, unported 452 heads, 1 3/4 in heddmans, performer intake,750 carb, and .509 purple shaft cam. All at 3550 lbs. Im thinking the dart may go a tick faster.
 
I'm not real sure, due to the 1 5/8 headers and the glide...that makes the guessing kinda tough.

For what it's worth, my car is about the same weight, 2 points less compression and a smaller cam and a 727 trans, and it runs 6.80's... so I don't see why not if the chassis is setup well...but like I said, the small headers and the glide are something I'm not used to seeing in a combo like this.

My guess is 7.0's @ 97mph...change the headers to 1 3/4 or 1 7/8 and 6.80's @ 99-100mph...just a guess.

Edit: I will add (since I don't know glides) if this was with 3 speed (727 or 904) and bigger headers I would guess 6.70's @ 100-101
