There are always better cams for any given combo,but you gotta ask yourself if you are willing to potentially spend big $$$ on buying multiple cams to try on the dyno to chase after what may amount to minimal gains.

And as I understand it,the Eheads max out @ 340-350 or so CFM before going to a wide port configuration,so there may a minimal gain there too,but again one has to ask themselves if it would be worth the trouble to do such.

CR is the real challenge,agree you may be maxed out there to still run it on pump gas.

Tell us about the rest of it,intake & exhaust tracts,rocker ratios and the like.

Might be something there to be had.

Honestly,the dyno time alone to do something like this properly would be pricey.

IMO there's always something more to be found if you look hard enough,but it's a matter of ROI in terms of both time & $$$$.

Maybe. Time for nitrous? If that is an option

I have a plate on it. I was told that with the cam I have I shouldn't go higher then a 150 shot though. I wish I knew if that were true...

With a stock block I'd limit it to 200 or less.

I went 9.90's with less compression, less cam, 4150 carb, less head and the wrong converter with a .73 jet @ 3700 lbs.

That's good to know. I'm always worried about the block.. Thank you.

Is a 73 jet a 180 shot?

I put a 63 in it and the car fly's.. I just have to get it to the track and see ...

I Believe more cam will get you there.
I got my camshaft from Scott Brown and that makes all the difference
In my application, My heads flow less then yours do and I think with
A cam like mine you would make a lot more power. As for as the n20
Try more you won't know intill you do, It's not like it won't make more
It's how much more (will) it make with more. The only thing about
running more camshaft is you'll need springs to handle the cam also.
I do believe with a better camshaft you will make quite a bit more power.
I am at more compression 12:1 and still pump gas. Hope this helps.
My LSA is at 113.

Yes , all guys are helping a great deal and I want to thank everyone for there input so far..

Do you have any time slips or dyno numbers?

Could you share your cam spec's? If not I understand..

Ok, 4500 victor intake, mad dog 2" headers 3 1/2 collectors with Borla 3 1/2 muff turned down at axle, 1050 dom. Rockers 1:6 .

Sounds like maybe I'm real close to max power?
