jub jub said:I would get the AFR 205 heads. They make great power especially with the right cam. I have them and I went with them for basically the same reason as you, so I could keep my original heads plus the power they were making. Quite a few folks running the G5X3 and the AFR heads making 450+ at the wheels. I'm making 440 with basic bolt ons and a mild cam!
I am positive that someone that does not know you, eamador11, will be more than happy to take your advise after reading your well articulated commentary. In addition, the massive amount of horsepower your car produces, is just as impressive. In fact, out the half dozen late model vehicles I have, they all produce more power, than your wondermobile.eamador11 said:Oh no another AFR vs. LS6 re-post! LOL Here..chime in to this one..its a novel
If you want to be talked into LS6 heads, talk to member Grim Reaper. Hes the CEO of CNC LS6 heads corp. and will tell it like it is! :lol: :lol:

Also would the injectors or Fuel pump need to be changed with this combo?
These are not 205's, and granted, it's not a Z....but it's a result none the less.B_P_fox said:Opinions .... everyone has one.
.... it's in the results :yeadog:
I am sure if you cut out 650 lbs., out your F-body and put in a 4.11 nine inch rear with a four/five link, you will be in the tens.tckylem said:Thanks for all your input. I have a 99 F-body that runs 11.6's with me bihind the wheel (I drive like a dead man.) I want track results in the 1/4.
The dyno is a good benchmark but, doesn't mean 1/4 is best. The curve is better.
My car has produced between 430 and 440 ft/lbs on 6 different dyno's....I know personally of at least a half a dozen others that have produced in the 430's and one other (stock displacement) that has hit 442 on a known "honest" dyno (LAPD in Chatsworth). That car had EVERY mod my car had with the difference being a larger, more radical cam...234-238 on a 111 LSA. It generated 492 RWHP that same day with NO dyno tricks, stock rims and tires, out of the box 205's and 11.2 CR on pump gas.THRLSKR said:Hey Tom -
What kind of TQ are you getting with your set-up; the 437 from LG was from Godspeed's car and appears to be on the high side.
Lou's car is no doubt an awesome machine and not intended for the dragstrip. The 140 mph trap speed is due to him running a superlight racecar and a relatively poor 60' time moreso than anything. There is no doubt in my mind however that all LG products are top notch and his tuning makes a big difference as well. I loved the video as well. Impressive no doubt.L G Motorsports said:Here is a graph of our G5X-3 cam and AFR heads with 11:1 compression and a 90mm fast and LG throttle body. Of course it has our LG Pro Long Tube Headers.
We upgrade the springs and compression on the 205s to reach the 486 number.
We upped the compression to 12.5:1 on one car and hit 535rwhp 482rwtq and ran 140 mph on a forged stock cu in AFR package with our headers.
Video link of 140mph run:
Give us a call we have AFR heads to our specs in stock now.
