850 carb is downleg booster ? Reducing plenum volume/ shape pointing to metering fluctuations into chamber Exhaust collector extensions would of soothed it a little End runner lash tests (ex) worth trying Figuring the power delta between centre and end runners helps(manifold dependant) Track testing...

To insight a bit of discussion I am curious on why peaks fell where they did and why it carries up top to 7000rpm. The only headers I could use were my 1 3/4" 4 into 1 headers Could not use the 13" extensions as they hit dyno frame. So shelf header with 3" collector at 6" long with a curved extensi...

My suggestion for a budget carb contact ATM. Otherwise get something custom from a more reputable company. Crossing plenty of lines here.. Being honest. I build carbs,and I have repaired a lot of those. I don't fault any company for their calibrations I may not agree with, as long as the components...

You are very methodical and disciplined in documenting against "internet data" - just understand that the Dyno numbers by and large will not translate to the "Best ET/MPH run" - by a large factor.
If this is your test against the rest .. so to speak .. Enjoy.

Spacers shine on the stationary dyno stand - you do not want slow fuel discharge and tall spacers in a drag launch scenario.
Paul does nice work.

Fortitude is the only choice

Joe, Jesel guy said a while back they 'may' be able to. Am really looking for someone who has actually done it and what was involved to get the geometry correct... Arthur, I would only use T&D or Jesel, not an engine shop as they don't build their own Jesels or T&D's. I doing this deal for a buddy ...

I've always found it a little amusing that the advent of the Zero-Gap ring was for use in air compressors...because they didn't have a one-way check valve yet. The compressor companies tossed then as soon as someone invented that little jewel. I also find it odd that one can attempt to make a compa...

Pretty much the most intelligent post in this thread, thanks Jay. =D> F'Bird, you are an idiot although some times you get it right, most times you do not. It's really sad that you have a following. Fuel curve is king. I could put a 1300 cfm dominator on a stock 283 and MAKE it work perfectly. Is t...

Because it uses fuel flow in its calculation, we tend to think that BSFC numbers are driven by fuel factors like jetting, atomization, etc., BSFC is driven by jetting, atomization,.... but by many other things too. What other things??? I've seen taking jet away improve BSFC at less power. I've seen...
