Yep, Thunder was my inspiration. I wish I had a 572!

well, I had a ecsb 4.8 with heavy *** 18(75lbs)each running 14.9 no weight reduction,no cam,no stall and spinning it to 6400, so getting a rcsb with a 4.8 should be easy lol hahaha sorry guys.

This is what your going to need.
4.10's,3000 stall,220 220 5?? 5?? 114 cam,918 springs,harden push rods,tuneing,underdrive pulley,elect. fans,cold air intake,ported t/b,weight reduction,slicks 26"to28",headers-long tubes are best but can get good results out of shorties, and then again more tuneing. That there should get you 13.?? easy on a perfect day.

 

so then i cant do it with just a muffler?????

 

No. It takes some time and thought to get a 4.8 to "wake up" and run. Look at Thunders set up. There is a perfect "13sec N/A 4.8" blueprint to follow. Now if it were me I would through some FI at it. But thats just me

 

just for info is fi forced induction

 

o the comment about muffler is a joke

 

ya FI is Forced Induction. Yea just follow thunder's blutprint like he said. (and add a little nitrous ) Good luck.
