Compared to .050" inch specs.The isky does look very good, and that crane made 571hp with advertised specs

I didn't see the isky 272 sheet with the inputs for the @.050Compared to .050" inch specs.

Gotcha. I may call to see if I can dig them up for data for future build reference.be good to know that way all the same data points are used
Agree, hood clearance is on the tighter sideWith a Cam chosen the Biggest bottleneck for many is using a stock steel hood and an intake that fits with a Fullsize air cleaner.
Like a Moroso 14 inch diameter unit.
At least a 4 inch tall filter element.
5- 8 inches tall prefered.
Impossible in many cars.
Packaging is tight often.
I really thought Grumpy Won last night.Gotcha. I may call to see if I can dig them up for data for future build reference.be good to know that way all the same data points are used
This is a really Fun project Grumpy.I really don,t care what cam "WINS" as long as the software dyno is FAIRLY matched, in the data being used to compare them,
with all the cams data put in using an identical matched system or method of comparison.
now in the real world, i have zero doubts as too the cam that produces the best power curve ,
and anyone whos done enough soft ware dynos is well aware that changing just a few minor factors makes a huge difference in the results predicted,
if you use .004 lift data on one cam vs .050 lift data on a different cam,
thats like trying to compare gals for a playboy fold out photo,
with one based on pictures when,
shes 22 years old vs one based on photos shot,
of a similar gal at age 72
that"50" plus or minus in the calcs matters
Ok.Here's the isky specs @.050. just got them
Probably so. I'm thinking I will go with the borla xr1s 3", x-pipe, Doug's 1.75" primary full length 3" collector header. I already have the headers and those borlas sounded pretty sweet. Add whatever cams you like, just keep it street able with decent vacuum. Car cruises around 2600-2700rpm at 65 if I remember correctly. Needs at least 10" of vacuum, so no crazy overlap. Stick with 1.6 rockers and the pro Flo setup. It's what I'm going to use. 35lb injectors. 6500rpm redline. No crazy durations. And don't forget about that high first gear. The more I talk about that damn first gear, the more I want to switch tranny's...$$$ money pit... Not trying to win a race either. Trying to sound nice. Drive nice, blow tires off at will. I know I'm not going to win a race, not trying to. Dependable valvetrain is important.If I have time I will run all with mufflers.
Should see 80-100 Hp drop .
Does anyone know what manifold vacuum readings Rick had with that Crower?
Thanks Rick, that's helpful!At 1000 rpm the vacuum is 10", idling in Park, Demon 750 carburetor.
