Slowly getting there. Still got a box of parts & a list of things to doNot needed for race only applications. Furyious is coming along well!!
I’m a curious fellow by nature & I love data. Perhaps I run them unwrapped for a season then wrapped the next & that way I can an apples to apples comparison. And that would give one less thing to do this year as I’m ready to go. Tired of working & want to play someI'd wrap em. Keep the heat in the headers. As John said the theory is they flow better wrapped.
So I only drilled out the one stripped hole & ran a 1/4 by 28 x 2 inch bolt through it. Not quite long enough so I’ll go back to the store & get a fine thread 1/4 x 20 x 2 1/2 & cut to proper size. Locking nut & star washer & the fellas tell me I’ll be fine
I only plan to run this center section for a few races. It’s a 3:73 sure grip. I broke that 3:23 sure grip last year. Just want to see if this is enough gear. Get some trap RPM data. Then I’m going to put a gear with a spool inI've sheared those stock bolts off before and the solution is to drill through the flange and install a larger grade 8 bolt (usually an allen head) and nut. If you are doing one, do the rest and be done with it.
