sorry to post another thread...I would love to hear any and everyone opinions on heads for the 4.7 especially the race prepped and economy prepped heads from airram.com... I will more then likely be purchasing one set or the other before the rest of my nitrous kit...please let me know guys id love to hear from someone with the race prepped heads...its going to be a long winter and my goal is, is to get into the 12s late next year with the 4.7 on a 75 shot of nitrous.. but im looking to get it running extremely well n/a but I met my goal last year and my goal this year is, is to have it running in the mid to high 13s n/a for mopars at the strip march 18-20

I know will be looking into heads relatively soon for my supercharged setup , but I am also working on getting my forged rotating assembly acquired.

Sorry to hijack your post, but I saw you have 4.11 gears & the truetrac LSD. How do you like them? I just picked up my Yukon 4.11 gears and was looking into either keeping the stock lsd or upgrading. Thanks!

Nice! uhm I will admit I messed up alittle on my mods lol I purchased the stock lsd from a junk yard with extremely low miles for like 100 bucks so I really couldn't go wrong! haha sorry about that I always thought they had a true trac from the factory...as for the 4.11s...theyre by far one of my favorite mods ive done yet!..i really wish I would've just went with the 4.56s because I have 29.5 inch tall drag radials but man you wont regret them one bit!...im not really worried about gas mileage but I will say I actually noticed an increase in mileage after the install...a lot more snappy around town...ive heard the stock lsd is pretty good but if you have the money down the road and time...go with an aftermarket one lol but ive heard the stock ones work pretty decent especially for the price...
