Mufflers
Hey fellers, I'm doin a pro-street build on my '69 & need ya'lls opinion on what mufflers to run. Right now I have dual 2" pipe off my headers into Flowmaster 40 series with tail pipes dumpin right behind the rear wheels at kinda an angle down. I'm runnin a .030 over 454, .525 lift cam Lunati 60201LK, old smog oval port heads I want to change, performer RPM with a 3310 vac. secondary and Flowtech headers from Summit. I've read that Flowmasters restrict alot & Dynomax or Borla is a pretty good flowin muffler. I'm wantin to run 3" pipe back to mufflers then a short pipe over the rearend turned down. I'm gonna run a full pos unit & keep my 3.73 gear. My truck will see the drag strip ever once in a while. If I find a set of 781 heads I plan on goin up a couple sizes on my cam, like the Lunati 60203LK & runnin a Hughes 2500 converter in my TH400. What do ya'll think?
