The converter has a lot to do with the sixty foot.
The track I was at yesterday has some questionable sixty foot clocks. I went 1.319-1.333 yesterday, where as last week they were all 1.35-1.37 all weekend at a different track.

Gday Rob,
Well done on the roughly :D
I looked at that one, looks good !
Crower añd lunati have some nice tight lobe center off the shelf stuff!
My flatty was 272 /280 , 106 in on 102. 660 lift.
Roller is 270/279, 107 in on 103. 670 lift .
Wanted 106 and 102 again, but piston and valves are a bit friendly.
Cheers
Ps i sometimes race at this one track and it runs awesome 1/8 mile mph, has to be the timers.

Yes we upped convertor to 5800 but may not be getting there. Will have to do a test in spring. We put a 4hole phenolic hvh style spacer on and that livened 60ft up quite abit.

My current converter stalls right at 6100. It used to go 6500, but I thought I was going to build a bigger motor and had him tighten it up a touch. That was a mistake for this combo.
My old Coan C4 converter would stall right at 6000. I used to run a stock rod, 358 inch motor with the c4, (basically the motor I ran last year), and it would go mid 6.30s to low 6.40s with an alchy carb in my car.

I ran a leakdown test today, and now I dont know what I am going to do. LOL
They were all between 3% and 8% leak.
At this point, I dread the thought of pulling the motor back out of the car and then having to put it back in. I might just pull the front apart, move the cam timing back to 102* ICL, then put my aluminum water pump on it for next year and let it run whatever it's going to run.
I have grown real tired of constantly working on it, and throwing real money at it, only to have it run exactly the same.
On the other hand, I would love to toss a different set of heads on it that flow 30 cfm more on the intake side.
I guess I have a few months to figure it out.

Rob 3-8% leak is perfect. Cant get much better than that? So you shift at 7400? The tq shop tells me you need 1500 differential. So 6000 stall 7500 shift.

Yeah, I am shifting at 7400. I was shifting at 7000 when the converter stalled 6500, and it worked fine.

Little more duration, little wider lobe separation. :) A 377 will pull harder on a big port head than a smaller engine. I think the 106 LSA is curbing your top end.

If you're interested, I'll send you a cam to try. If you like it and it picks up, then you can pay for it. If you don't like it, then pull it out and send it back.

I don't think you can get any better of a deal then that.

How could it get better?
Brent could install it and bring the beer?
