I swapped my setup around a little bit, and i love the results. My old setup was a forged 347, a set of TEA TFS 215's, an unported fast intake, with a built 4l60e w/ a yank ss4000 stall. This setup made 438rwhp/396rwtq locked @ XXX Motorsports in Pensacola, Florida. This was also on a set of Fikse M5's with bfg drag radials. I had taken the car to the track which is only 1/8th mile and it went a 7.36 1 time and a hole bunch of 7.4x's@ 92mph. it cut an average of 1.60-1.65 60ft. I than wanted to change up the setup to try and get an overall faster time and better performance. I saw some solid results with the AFR 205's which i saw no need to go with AFR 225's because it is still a stock cubed motor. I than decided to purchase these afr cylinder heads and i also wanted to try a ported intake. I got a hold of Tony Mamo and he really came through for me and helped me out immensely. I than ordered a Rossler TH350 w/ a T-brake. i also added a new converter which a ordered through ATI in which i gave them all the specs of the car and what i was going to be doing with the car, and they decided on an 8" 3800 stall. I got all the new parts in and put them on. Overall the only parts i changed was the Heads, Intake, Converter, and Transmission. Everything else stayed the same. i got the new parts put on the car and than had it retuned @ XXX Motorsports. i had a set of Drag Lite 15x8's with a set of Quick Time Pro 27x11.50x15's in the rear. The car now made 405rwhp/374rwtq unlocked. it was a little warmer when i had dyno'd the car before when it made 438rwhp/396rwtq, and it was a little cooler when i dyno'd it with all of the new parts. The only difference between the chambers in the cylinder heads are the TEA TFS where 60cc chambers and the AFR's are 58cc chambers. The car has an overall raceweight of 3650lbs.(it needs to go on a diet) I knew the car wasnt making as much horsepower on the dyno but on the street it felt like there was an UNBELIEVABLE difference in performance. It was a very nice day out today. It was roughly 55 degrees out which was about 10-15 degrees cooler than before when i ran the old setup due to the difference in the time of year. I took the car to the track today with all of the new parts and it really suprised the crap out of me. The track was very well preped so it was a good day for racing. I did not believe the new times that it ran. Overall, it went a best of 7.19@ 97.21mph with a 1.55 60ft off of the T-brake. I still do think that there is more left in this new setup the way it sits, but i am still getting use to the new combo, because i have never owned anything this fast before.

Overall, i am very glad with the decision i have made with going with the new setup, and now i feel like i actually own a car that is a little faster than your average h/c fbody.

Man, that's a lot of changes to pinpoint the difference the heads made, but glad to hear it's running well.

Yeah less then 2 tenths from those changes. I doubt any of it came from heads besides the fact that your now running higher compression...

 

i think the main difference that i noticed and liked was the huge difference in mph, 5mph is a great step up and i think that also had to do alot with the intake and heads. Im not saying that is the only reason, but it is just what i think is the majority of it.

 

So let me get this straight...you swapped heads, ported intake, transmissions, converter, wheels and tires, added a T brake, ran in 15 degree cooler weather, had higher compression And then make a thread title that sais

 

im just stating all the facts so that everyone knows all the little minor differences. i could have left out the converter change the weather and what not and just said a th350 with the afr heads and ported fast intake but i figured that wasnt all of the variables so i stated everything!!

i figured it would be more benificial to people to know everything than just half the details.

 

You probably could of just put in the new tranny and converter and ran those better time's. The trans brake is probably what helped you the most!!!
Cograt's!!

 

What are you going to do with the old trickflows?

 

they are already sold but i have a built 4l60e and a vigalante 3800stall for sale


hahahaha

 

Why did you switch heads?

 

X2

 

How much did the custom ATI converter run ya ?

 

Glad to see such an improvement with less HP and TQ.

 

yea I was looking for an apples to apples comparison myself, I am dissapointed to say the least.

 

Yeah, pretty misleading title.

 

The th350 and convertor alone made the difference...

 

It seems the Driveline alone helped ya alot buddy but nevertheless great 1/8 mile et

peace

 

+1......

 

If I understand what's going on there and to summarized my thoughts:

At the track you are close of time done by lighter cars with more Dyno rwhp...
Is that correct???

Congrat on options that are making you faster!!!

Christian

ps: not sure if dyno rwhp are telling everything...

 

i swapped heads because i had one of the first sets that came out and which they had the problem with running stock rockers caust it was eating up the tips of the valves, I didnt feel like waiting as long for the new ones to be shipped to me so i decided to overall go a different route.


and the ATI converter ran a little over $800 if i can reacall correctly
