How To Measure Fuel Volume.

Now that you have posted your combo, I can pretty much guarantee you a “ real” convertor would really wake your combo up all over the time slip.
Would be nice to know how good the heads truly are, but that cam is almost 250@50, it’s gonna pretty much be a dog at where the convertor you currently have is hitting at. It would probably like something 42-4500 for sure. Even more.
You mentioned the cam, from what I have seen, it’s ground on a 108, it’s likely gonna be most happy stuck in at 104. You didn’t install it straight up at 108 did you?
If my understanding of that cam is correct, the above could really affect the time slip too, especially with the vert you have.

I’m thinking a converter would help too. That’s not in the budget now.
Cam is at 108. Would 104 lessen top end charge more? It would probably help the idle, if nothing else.
I also would like to avoid getting to where I need a roll bar and the pita 2 year belts. That sucks doesn’t it? The rules, though for everyone’s safety, dissuade me from going quicker.

113 with the 26" tires would be 6600 in the lights. With 28s, around 6100.i think the taller tires are a good move.
And (according to wallace) that 92 mph 1/8th pass should have been a 113, and about a tenth quicker.
Find somebody with a valve spring pressure checker for on-the-head.

And, I agree with ^^^^^^^. A 4200-4500 converter will be a dramatic improvement, .... if it hooks.

Hooked pretty good with the 235 MT ET streets. I only have front clamped slant springs and loosened front suspension. 28’s are 265’s. Cal Tracs are the long term goal.

“I would be more worried about 7" of vac @ 1200 rpm. Seems very low...”

That’s what it had before I tore it down for inspection. Hasn’t changed. Maybe the cam at 104 will help.
