I put my LT1 build up on hold for a while. I am going to start building the shortblock pretty soon. I need to decide on which package.

I have been dead set on going with an AI 200CC heads and cam package, but I recently saw somone with a kick *** AI TFS combo.

I am looking for mostly track times, but if you have dyno numbers you can post them to.

 

the tfs heads are going to be the exact same thing but they have the potential for more. A few people on this board talk that their better than AFR's because they re so much newer of a design. If you can afford them i would go with them. Track times are going to depend on a number of different things but figure 11's or faster.

 

Both have the potential of taking a car well into the 10s on motor. Both have gone into the 9s with the right setup. The TF head has more potential and I've heard from Phil is a much better casting than most of the other companies put out.

If you go on Ai's website you will see the LT1 results page at the top. Both have gone 10s with solid roller setups. Both have gone 9s on boost/bottle etc.

 

Check my sig for some track times and dyno on the AI 200cc heads. I am aiming for lows 11's or maybe even 10's next summer.

 

10.60s at 128mph with the tfs heads and I think the car will go faster after some suspension upgrades this winter

 

My car is geared for the 1/8, but if I swapped gears to 4.56's I'm sure it would run 10.50-10.40's, and I believe there is more on the table. If I could get some tuning done at the track I know I could pick up tenth easy.

Subscribing....

Might just have to buzz Phil/Ron sometime this week.

 

Sorry to go off topic here but I was wondering what you go through the traps at with the 456 gears.I mph about the same and my motor will go upto 7500 easy just wondering if I should give them a try

 

The TFS heads that AI produces are extremely stout.

I have AFR's right now, if I was to change in the next few months those would be the heads to pick up.
