How would this cam perform in a n/a lq9 with l92 heads milled .015 with a .040 head gasket for a 11.0:1comp. At .050 the specs are 117+2 lsa 226I .598 lift 238E .600 lift on xe-r lobes?

 

Should have decent idle quality..

 

Intended use? Drag racer? Fun street car? Autocross?

 

Good idle quality with -2* overlap, high revving, low-end should be ok but nothing great.
So, what are your goals and use with this cam..?

 

That cam itself won't make a lot of power, but should have great street manners and drivability

 

87 buick regal 2800 stall 4l60e 3800lbs 3.42rear gear 27.1" rear tire street car some strip mainly over the road daily ddiver may hit it with a 150 shot. My bag forgot details. Thanks all

 

What is not a lot of power? 380 rwhp? Was hoping for about 420rwhp. Has 1 7/8 long tubes to 3.5" collector to 3" x pipe to3"all the way bac.

 

IMO, You need to either to go with a smaller cam or higher stall TC. Even with a higher stall I'd go with a little less split and drop the lsa down to 116 along a little more advance on the cam, like a 226/234 116lsa +3.

 

With what you have mentioned here, I would specify:

223/230 .610"/.609" 112+5

This will give you great low-end power with your small 2800 stall and the large port volume of the L92 heads. This will also give you great driving manners as the camshaft 2 degrees of positive valve overlap @.050" lobe lift.

It will also respond very well to a 150 shot.

 

What kind of lobes are u reccomending? What is the icl of this cam sir?

 

Trying to understand these #s. So does 112+5 mean the the icl is a 107 and the exhaust is a 117ecl? But dont know the lobes. Will this creat ptv?

That looks like Comp Cam 223 lsl intake lobes and lxl exhaust lobes.
Yes, 112lsa with a 107icl, with a 117ecl.
That not much overlap at all, you'll likely be fine but it best to check ptc clearance to be 100% sure.

OMI, those are better lobe choices than the xer lobes.

 

So what would be rhe rpm range for this camshaft?

 

LSL/LXL. 107 intake center line.
Correct. 107 ICL and a 117 ECL. IMO this is just slightly smaller than I'd want to go with the amount your heads have been milled.

I would verify P to V when installing as your heads have been milled a fair amount along with the size of that intake valve. Also you mentioned a .040" gasket which as you know will decrease P to V even more.
Correct. I also prefer them over the XER lobes.
Peak torque at 4400-4600 and peak horsepower at 5800-6000rpm. Shift at 6400-6600rpm.

 

Thankyou for the cam recc. What would u suppect the cam specs I posted would be used for or best suit?

 

I'd think a super-charger build would suit those cam specs, but I'd still rather see it with either LXL or Extreme RPM(high lift) lobes for better valve train stability with boost.

 

Someone said it wont make alot of power. What is alot of power from this cam.just plotting numbers in my head

 

Which cam?

 

I think he means the first post specs.
