It's on the 'to do' list for sure.

Update - Tested at Fayetteville NC this weekend, BIG steady headwind.

Best of 14.97 @ 85.44, 60ft 1.923, 8th mile 9.23 @ 70.26. So it went under both 1/8 mile indexs and IHRA 1/4. Still need a little more for NHRA 1/4 mile (14.85). Biggest change was adding 18 more inches of collector for a total of 25". With this change, it seemed to want less jet than before. I had cheap paint on the collector looking for some to burn off, but that didn't happen. Seemed to be a semi-significant heat differential around the last 7" of collector(last 7 were cooler) so may shorten them there. Any suggestions?

What is your rpm through the lights? Maybe go to a 5:37 gear?

I'm considering that, or more. It's 5700 rpm right now. Is there a 5.57 for a 8.5 ten bolt?

I would like to try a smaller tube header, 1.5 primary but don't see any available, pretty much spent two days on the internet looking.

Also, I should say Joe Huestis is a BIG help on this deal, he was right there this weekend. Thanks for your help, Joe.

Motive Gear, Precision Gear, others have a 5.57 for an 8.5" 10 bolt.
