I have been working on getting the maverick ready for the track for a couple weeks on and off. I got some et street radials, installed a tach and so on. Well today was the day of reckoning, we trailer it to the track. I go to make the 1st pass and its at 160 or so degrees. pull in the box and do a nice 1-2-3 burnout. I pull into the beams against a 03 cobra. The lights come down and I go. The car transfers nice and I see a 1.89 60ft and the car goes down the track without missing and so on. I get my et slip and was crushed, turns out the car launches good but has no power, the et was 8.60 at 79mph. After that the car went a bunch of 8.70's. All in all I have decided for now that its a nice street car and definitely not a race car. Owe well I was really happy for a minute lol
I feel your pain, that's slow for a 351... The std bore 5.0 in my 3750 LB T-Bird would run 8.40s@82mph on drag radials and I drove it to and from the track, don't own a trailer... Currently she's down with a blown head gasket...
great 60 ft time. whats the rest of the car build becides a 351? whats done to it? what gears are in the rear?
noo dont get discouraged, what converter do you have? when i changed from the 3200 to 4500 it was like nite and day.what was your timing set at? intial and total. i cant remeber what your build was been so long since we talked , but you should easily run in the 7's. anyways dont give up on it .and if i can help let me know.
I didn't build it but this is what I was told 351w stock crank and rods with flat tops le mans cam, basically a low lift high duration 40 year old design lol 68 302 heads, supposedly ported with 1.94 1.50 valves air gap intake and a 650 demon, I tried my spare 650 holley dp and it made no difference c4 3500 stall, 4.11 gears and 255/60 et streets
hey im an over 40 year old design myself and i do fairly good lol. what rpm were you launching at and shifting at?
lol, I was launching anywhere from 1500-2400 rpm trying to find a sweet spot. I shifted anywhere from 5k to 5600 rpm. around 5300 seems tp work best
You need a good set of heads and better cam... I have Trick Flow heads and cam in the Bird with only a 2600 stall & 3.73 cogs, will pull hard to 6K plus... I dunno what cam to recommend as I don't think TF sells a flat tappet that's matched to their heads...
The older cams were designed to work within the limitations of the factory heads. Either the camshaft is a mild grind or the ignition/ fuel curves need tweaking. Not knowing the cam specs the combo sounds good tho.
this is what I could find online about the cam Intake Lift: 510 degrees Exhaust Lift: 510 degrees Intake Duration: 318 Exhaust Duration: 304 Degrees Intake: .020 Exhaust: .025 Intake opens: 52 degrees Exhaust opens: 82 degrees Intake closes: 86 degrees Exhaust closes: 42 degrees 94 degrees of overlap: Intake & exhaust valves open at the same time
