1/4 ET : 15.334
MPH : 89.51

The last run it was starting to sprinkle so I called it a day, Im reasonably happy with these numbers considering its a 305. I had no traction issues whatsoever after the first run (third run had a little bit but the track was getting damp) it was about 60 degrees with 78 percent humidity.

So were these good times? Where should I go from here? Im already getting ready to build a 350, but are there any cheap mods to be done to the LG4 to drop my time?

 

A 150 shot of nitrous.

 

HP is consistent by comparing the MPH. Traction is an issue looking at those 60' times.

It's making roughly 190 uncorrected hp estimating a 3300 pound race weight.

 

I'd be looking to get that 350 together. I was going to try to give some suggestions to make that car faster but i'm not sure what to even do. MAybe put in a cheap jegs cam ($50) and put in a 2400 stall converter and a pair of drag radials. You would get it into the low 14's i'm sure?

 

Well, if he was goig to stick with the 305, i would give some suggestions, but he is going 5.7, so there really is no point in wasting money besides a nitrous kit.

 

The only traction issues I could really feel was the 1-2 shift, it chirped em everytime, the last run was the most noticable, but as I said, it was a very damp day. That very well may have messed with it, I am gonna try to make another trip out when its drier, and see what I get. I was hoping maybe to drop it in to the high 14s before I do the engine swap. Maybe do an aftermarket air cleaner?

Also, is there anyway to make it shift into 4 at WOT, this was killing my time, I had to let off so it would shift then get back on it.

 

.... almost

 

the single 2.5" dynomax exhaust could be a choking point, and it will be a choking point when you put the bigger motor in so go ahead and upgrade that and you should see some pretty decent gains.

 

Ill look into getting a quote from a local exhaust shop. Im gonna have to have the y-pipe modded too, the only reason I went 2.5 is cause I was running out of monay at the time and needed it on the road.

Also would a HEI Incap supercoil help me out at all? There a very good chance I would be reusing it on the 350 anyways.

 

2.5" will choke about 20hp out of your motor at least.

You can do a few additional things for cheap HP:
Electric fans if you have a clutch fan
Underdrive pulley
Tune carb using an A/F gauge

 

What exactly to underdrive pulleys do? Are they good or bad for the street? Its something I am interested in seeing as I can reuse them on the 350 when I do the swap. Also I am gonna try to get a quote on an exhaust today sometime. Im also currently looking for another 700r4 to build myself, seeing as mine is messing up the 2-3 **** really badly, revs to the sky, I have to let off for it to shift.

 

You don't want to go into OD. You want a different gear in the diff so you cross the finish line at or just before you need to shift to OD. A taller tire will also help. The ones you have now are less than 26" tall.
