I was looking at what to do next after this summer. I am working so I will have some money to do some stuff. Mods are in sig, I will get slicks and a copy of LT1 edit first, then I was thinking :
1.) 58mm Throttle body (which brand is best, monoblade?, any advice on these?)
2.) Longtubes (what brands are best now? I have seen some pacesetters locally, SLP, FLP?)
3.) Nitrous (will do this anyways, rather get it running best N/A first though)
4.) anything else?

just looking for some advice, I was running 13.08@108.7 before at 5200 density altitude (3300+ ft) with some 2.05 60's. cant wait for my slicks, but I would be very happy with some low 12s later this season at this altitude.

any help appreciated

 

i'd do the throttle. that will give you the best bang for the buck...

and if you desire any type of clearance for speed bumps and potholes, i'd go with AS&M mid length 1 3/4" primary exhaust setup. it's nice, gives decent power, only about 5 less than long tubes, clears the same as stock, easy to install, and easy clearance for plugs/wires too. plus it's emissions legal...so there will be no 'plugging' anything. you can also pick up their 58mm tb here, and its the only one i'd suggest. there's too many problems with holley, and edelbrock is too expensive.

 

I already have Mac mid length headers and custom y-pipe, only reason I would spend any money for the upgrade would be for Longtube (maybe 10-12 rwhp? in my setup).

I will look into the 58mm TB from AS&M, any other suggestions?
