Systemax or AFR?

Rick 91GT · 12-19-2001, 02:49 PM

Well I'm going to be different and say te kit is great, atleast it has been for me. I had the BAD heads and went 12.6 @ 108mph full weight. I swapped out the non-emissions cam and went to a AFM N-61 .544/.568, 228/236, 110. I fly cut the stock pistons and added a 8pt cage and lost the P/S and A/C and went 12.16 @ 111.5. The 24lb injectors were going lean up top so I went to a 30# injector and 75mm TB and I have went a best of 11.92 @ 112.8 still very rich (I need to do more tuning on the Speedbrain, I have went 114.9mph on the stock EEC)

With the correct gear that the AFM cam is ground for I hope to go 11.40's or quicker still with my NA 302.

If the AFR's were out I may have went that way but the flow numbers on the Holleys aren't bad, better then the E'Brocks and any Motorsport heads and even the Trickflows from what I have seen. A buddy at a local shop has been doing lots of flow testing and has seen some very poor flowing TFS heads right out of the box, So far the E'brock Vixtors have outflowed anything they have tested even a set of TFS-R's.

The Holley is the best intake out in my opinion that accopnaied with any decent heads should get you to your goal.

Good Luck,

Rick
