Looking for suggestions for my Street and Some Strip 72
Hi guys, I've been doing some upgrades on my old 72 SWB and I'm at a crossroads. To spray or not to spray. Truck started out as a weekend toy and ended up at the drag strip and I love it ! Built the stock 350 .30 over, SRP Forged flat tops, Vortec heads with screw in studs and guide plates, 500 lift solid flat tappet cam,254/254 at.50 and 110/118 llobe Sep ,MSD pro billet distributor,6AL box with 6200 pill,Stock crank polished and balanced, forged Scat I beam rods, RPM Air Gap intake, AED 750 HP/HO carb, TH350 with shift kit, 2600 Stall, Detroit True Trac rear end with 373 gear and 275/60/15 on 8 in rally it went 8.30 at 80 mph. 60ft sucked at 2.1 on street tires..Looking at getting some new MT ET Street SS in 275/60/15 or ET Street R in 255/60/15 to give me a little more gear..What would you next besides drag radials to get me in the high 7"s and still be stretchable ?
Tapped the rings for a 150 shot but want to get in the 7"s without NOS. Thanks Mark |

Thats a whole lot of .050 for that engine combo. Just a thought. Also I would start with trying to get the 60 ft time to drop off some. Of course without NOS.

Re: Looking for suggestions for my Street and Some Strip 72
I was thinking along the similar lines, 254* @ .050 is a lot for that little of cubic inches and paired with a 2,600 rpm converter is adding to the lack of 60'.

Re: Looking for suggestions for my Street and Some Strip 72
What have you taken out of it weight wise? What shock and spring are you running? I am assuming it is still trailing arm. What gear?

Re: Looking for suggestions for my Street and Some Strip 72
Is that 750 a DP or Vacuum secondary?

Re: Looking for suggestions for my Street and Some Strip 72
The truck is stock 3900 lbs so no weight taken out. I'm running a 373 gear. And the AED carb is a double pumper,75 jets in the front and 85 in the rear. I called AED and told them what I had and that's what they sent me..As far as shocks it's bone stock but I'm about to adjustable for front and rear and yes it's still trailing arm . Thanks

Re: Looking for suggestions for my Street and Some Strip 72
He hasn't logged in since 5-25 and only has a few posts. Maybe he hasn't even worked on it, or maybe he just popped in for some info and thats it (it happens a lot, and thats ok). I wouldn't worry too much about it dude.
