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

Get some wider/taller tires on the rear. If you can hook them up you'll be able to take more advantage of the high stall converter. That will lower your 60' times and get you into the power band of your engine sooner. The street tires are holding you back.
What's you trap speed at 1/4 mi?

Actually, a wider, stickier, shorter tire would probably help more, by raising the effective numerical gear ratio. There are lots of choices available these days for DOT approved drag tires that can hook HUGE amount of power with the right suspension. Maybe even a set of slicks....they can be picked up on Craigslist pretty reasonable sometimes.

Gotta disagree with that shorter tire thang! He's got 4:10's in the rear already. I've run a 2.02 60' and consistent 9.24's @76 mph in the 1/8 mi.with 265/60/15's with a 2.73 rear, weighing 4,000 lbs. His short bed truck doesn't have much weight in the rear to keep from smokin' the shorter tires.

That's equivalent to about a mid 14 in the 1/4,
My Vega goes 6.90s in the eighth,
I'm talking about a tire and suspension that will HOOK, a shorter tire will make him quicker, notice I mentioned DOT drag tires and slicks? , not regular street tires.

Yeah man! mid 14's in the quarter? My second gear was just starting to get wound up at the 1/8th finish line. I never had it on a 1/4 track but I imagine I would still be in second at the 1/4 mi. line with those 2:73's. I'll bet your vega weighs over a thousand lbs less than my lead sled! Here's a pic without the 265's on it. It had good weight transfer for sure with a stock converter.
The 455 really got er goin'.

That's my whole point, with shorter tires that HOOK, you'd be likely to actually get into third in the 1/4, and at least into the "meat" of 2nd in the 1/8th. The Vega weighs about 2900 lbs.
