i got a 94 lt-1 ran 14.2 when got it. I've removed all emissions and a/c system under hood an under dash also removed air bags and abs stuff,swapped both front seats to racing seats an i've installed a lt4 cam,30lb injectors,ported an polished intake,twin 58mm tb,long tube headers,ewp,tubular k member with manual steering,6al box,8.8mm wires,3 step,relocated altenator an battery,turbo 400 with 3800 stall w/trans brake,ford 9inch withh 4.11s an a spool,all tubular rear susp.parts,relocated tork bar,frame connectors,strut tower brace,3.5 skinnies up front an 275/60/15 et dr n rear, ran it for the first timetoday only got a 12.65 @ 105.36 60ft 1.67,330ft 5.10,1/8et 8.00,1000 et 10.52

 

Did you go all the way with the cam and valve train? It was just a stock LT4 cam? It does seem a tad low, but it depends on a lot of different factors. Do you have a good dyno tune? All this stuff matters a lot, which I am sure you already know.

 

I'd be looking for more. My stock long block and bolt ons before boost was getting me 110-112 trap speeds. But I'm at sea level and have a 3rd gen body.

You could be picking up some knock from the headers. And a dyno tune would help. Nice 60 though.

 

Fueling too lean ?? Any signs of fueling problems ?

 

The 105.36 is not sounding right 60ft time is good, but for some reason that mph is not what it should be.

 

Was it tuned? You didn't mention it.

 

I also did 1.6 full roller rockers and .600 lift drop in springs,255lph fuel pump an had pcm 4 less tune ecm.other than that engine is stock an has 108,000 miles on it.I was launching at 3600,shifting a 6000 tires where at 15psi.it was 93 degrees an 85% humidity.

Enough said lol

 

lol ya that will do it. Good 60' I would go back on a less humid and cooler day and try again. Should be around 110 atleast Id think

 

At least 110-113 mph..on a cooler day should be no problem..

 

so i don't see any work done on the heads,are they stock?
If so then I think it ran good considering the heat and humidity.
Get the heads done and it should fly.

 

You ran out of steam. A lot of variables here and testing and seat time are a must

One track time cannot answer weather your car was running what it should or shouldn't

What was your 1/8th mph? Btw. I'm figuring 89 to 90. If so that is only 15 mph gain
Out back. So you could have valve train issues excessive tire growth from temp
Fuel going lean timing issues or like what was said before dense hot air is very bad

I like to see more track times

 

no head work just a small cam i think i might be over rev n it also the card in cam box says from idle to 5000 or 5500.im going to try to get back up there this weekend.im going to raise take off to 3800 and shift at 5000 an 5200 to see if that helps

 

Also you need to verify that your stall is flashing at 3800 or before. Just so you don't jump the ligjht

 

ill test it n front of my house first to see what happens.i live n the boonees lol
