Quicker quarter mile times

hey guys newb here. I own a 84 c10 shortbed pickup and i just ran it at the track for the first time last night. I cant say im dissapointed but I was hoping to break into the 13's but here are my times
r/t .052
60' 2.101
330 6.083
1/8 9.329
mph 75.08
1000 12.185
1/4 14.644

The truck started out bone stock with 62k on the clock with a 350 sbc. So far I beefed things up a little with vortec heads, comp xe284h cam, flowtech headers, 3 inch pipes into spintech super pro streets, dual plane performer rpm manifold, tuned quadrajet carb. Im also running a tci th350 with a 3000 stall converter and 410s.

Im just Curious if anyone had some input to help me bring them times down a little. I was running street tires so i could only launch around 2k without it breaking loose. Also i was looking into getting a set of roller tip rocker arms, are they really worth the expense? Thanks guys

I don't think higher ratio rocker arms will make any noticeable difference. Vortecs flow well on up to about .480-.5" lift. No need to put more strain on your valve train.

You're truck is probably already capable of 13's. I would look into some traction adders like Cal-tracs and slicks. Maybe even install a trans brake. Might need a touch more stall so it'll launch at max tq. Say 3500.

buy a nitrous kit. and get rid of the vortec, they sound cool but they are really just restricting pieces of junk.

Yeah i was going to just run 1.5 roller tips. I figured i have enough cam to not need the extra lift. I originally was going to run a 3500 stall but i drive the truck on the street pretty often so i went with the 3000 to try to keep my trans temps down. Im still running a clutch fan so im going to look into some electrics. When i launch i dont have any wheel hop the tires just spin would the caltracs help the spin or should i just try some radials?

Really? alot of people have good things to say about them, and seem to run some pretty decent times with a gm factory head

You talking about the highest flowing production heads Chevy EVER made, not junk by ANY stretch of the imagination. Are there better heads available? Of course, aftermarket, but what he's got will work just fine, probably better than most aftermarket heads, for what he's doing. I'd suggest working on traction, Cal-Tracs WILL plant the tires harder, maybe look into a shorter, stickier tire just for the track.

Some 1.5 roller tips will help with friction, but I wouldn't go with a higher ratio. You probably wont see hardly any results on the time slip though. If you look at some flow charts, vortecs sweet spot is right around .480. A full roller cam setup would be worth the $$$ though. They're pricey though.

I still think you're leaving some on the table with the motor as is. If you drive the truck daily then I would stick with the 3000 stall. A 3500 can be a little to much on the street.

I'm thinking you're not getting wheel hop cause the tires aren't getting traction. You can always do it a step at a time. A set of slicks, if the truck starts to wheel hop then get some traction adders (caltracs or at least ladder bars).

Here are some plans how to make some homemade caltracs.

Put your efforts into your launch and get those 60' times lowered. It almost sounds like you might have rolled the beams.

yeah thats what im shooting for the next time im down at the track. I just couldnt get on the converter because of the lack of traction with street tires and stock suspension. Plus if anyone here is familiar with atco raceway in nj there is no way around the wet box which is horrible for traction on street tires

Try just some slicks first, and play with different launch rpm's and maybe air pressure. Your 60 foot is what's killing you. If you can get a better launch, with the suspension as is, you should be in your 13's. You're not that far away now.
