Hopefully I can catch you at the track sometime and check your truck out and see a couple runs. How do you like the coil overs up front?
dont go to royal purple to often i will more than likely be ready for october madness i usually run at evadale raceway. as for the coil overs i like them very much, i got the tubular control arms just to have to modify them cause they dropped the truck 4 more inches which put it way to low...so i modified them and now have more use out of the shocks

that was a nice setup, i came close to switching my nitrous system over to the same plate system youre running, think i even asked you about it at one time! one of these days ill get the full run before i change anything again lol!!


i hear ya on the lost of low end torque i heard or read the samething this is nothing a stall or some juice cant take care of lol!! nice 60 ft for a ecsb i think the best i cut was a 1.63 in my ecsb back in the day the last few times out in the rcsb i finally got the suspension right and started cutting 1.41's on motor didnt get a chance to hit it with the juice though but then again i made changes lol! since trans went out on some street runs

Yup I have looked at your build too your the one that helped me settle on the 370 lol. Yours and Skeets trucks seem to love the square ports and run great.

I agree w/ skeet & Tyler. With your setup and converter, I don't forsee any loss of torque down low being a problem for you. I would stick with the 250cc LS3s and let her eat! Let me know if you need any help!

ls3 heads on lq9 modeled after skeet's original combo. ls3 heads i ported exhausts only and run psi ml1511 springs on a 232-238 with 4l80 3800 stall and 4.10s. wish i had a transbrake or 4.56s to optimize n/a performance but my truck is a daily driver. happy is an understatement

Well lets hope so because heads are ordered should have them next week possibly. How do you like that stall on the street from the advice of others im going to go higher than the original 3500 I planned on.

daily driver is only an excuse from not being able to handle a beast on the streets lol jk
