Help with cam selection?

I'd chose the first one. That big one on a 110 LSA is going to be lazy without a power adder and don't expect much out of it below 3,500 and you'll never get it back on the top end of the RPM scale to justify what you'll give up on the bottom.

You'll also have to perform some serious idle circuit work to that carb to get it to idle on the idle circuit cleanly. Either way, the Howard's cams are nothing special. They're not cam designers, they're cam copiers. They are symmetrical cams.

Why are you messing with hydraulic cams..? Neither one of those cams are going to RPM the way you would want them to. The wider LSA you put in that engine, the lazier it will get unless you start shrinking the valve timing or throwing a bunch of compression at it.

If you used the fel pro 1094 head gaskets then you have 10.26 to 10.38:1 compression

The vortec heads really lifts more lift on the exhaust side than intake. Same with duration.

Both of the cams you listed has .470" lift on both sides

Have you modded the vortec heads for more lift? If so you can pick up some power by getting closer to .500" on exhaust side and .008 to .012" less on intake side

The 110991-08 is not a good match at all for this combo. Single patter duration and lift and 221* with a 108 LSA.. I think this will build too much cylinder pressure for 92/93 octane fuel

You need to widen the LSA or go up on duration

The duration and LSA is about right on the 112591-10 cam but I would still like to see a .008 to .012" spread in lift

With the 112591 cam, I would say 400-415 HP @ 6000 rpm, and 425 ft lbs torque around 4000 rpm or so

***EDIT***

I have to disagree with Shaun here. Shaun did you see his parts combo and figure up compression? I did. He's over 10.25:1 compression.

Telling him to run a small duration, short LSA cam will cause detonation at his compression levels.. Again it's not a 9:1 engine.

If he's running the 1094 head gaskets then he is over 10.25:1 compression.. With that and the 222* cam with 108 LSA will put in around 205-210 psi cylinder pressure

For most people I recommed 185-195 psi cranking cylinder pressure

Cam decision is approximately understanding the place you desire the horsepower and the RPM variety you going to function in. once you pass above a 290 era idle starts off to go through and capability shifts to mid-variety. Above 3 hundred and idle gets tough and the capability band strikes to the better end if mid variety. as quickly as you pass the 320 mark idle is complicated, plugs foul and capability brakes are ineffective. Now remember while some one says low rpm it truly is under 3000 rpms, mid variety is approximately 6000 rpms and extreme is interior the 8000 rpm variety on up. except you have had up-grades carried out to the valve prepare- do no longer plan on turning over 6 grand. in case you have no longer invested in high quality rods, crank and pistons- stay under 8 grand. for many street purposes a 290 era cam is approximately all you will desire. The 280 is greater of a torque cam, and can be my selection. Torque determines cost of acceleration. bring up is a distinctive question and that i will't locate my notes on that concern remarkable now.
