No worries. I just sold the 92 LS swapped truck I built. I drove it for about 6 months...[cl
 
At Frog Follies, I got the chance to park next to another AD flatbed

Time to make it a hot rod again. I bought a pair of 200 cc Sprtsman II 2.02/1.60 angle plug heads and mild stall converter.

Anybody ever ran these heads on a 350? What cam did you run?

Good to see you, Flipper. [cl

Nobody has ever explained camshaft theory in a way I can understand. Call me a retard, but I've always been better at fabrication and welding than engine building. [S

I've always turned to people smarter than me for cam choice. I'd be happy to ask one of those smarter people what they'd recommend for you...

A good all around cam is the Extreme Energy 268H Comp Cams grind number
CS XE268H-10
Pair this with your heads and an Edelbrock Airgap intake with a 650 Holley and I think you'll be pleased.
You can use a stock torque converter but, I'd go with a 2,000 to 2,200 stall.
The number one mistake made by people is too big of a cam and the second biggest mistake is too big of a carb.
 
The intake runners are a little on the big side for a 350 cubic inch street motor. I am a little concerned it will be lazy down low. I already have a stall converter for it 2,200-2,800 is what it is advertised as.

Right now, I'm thinking about Summit k1105 or k1107. People say they are old grinds, modern grinds make more power. Maybe so, but they are also hard on valvetrain parts.

This won't be a racecar, but I would like for it to be rowdy and sound good.

Agreed. My 455 has a 268H and it's a good cam.
 
If you want a rowdy sounding cam I doubt the 268 Extreme Energy will satisfy you. Maybe the Thumper series would be a better choice. Anyone have experience with them?
 
Not sure about a thumper cam. I want more than just sound. I want to burn the tires off at will too.

At one point, this truck ran high 12's. I'm thinking maybe low 12's or high 11's this time around.

It already has 3.5" flowmasters underneath it. It will make noise.
 
I have a Comp Cams Extreme Energy XE274 (one step above the 268 cam mentioned above) in a 406 sbc in my Crosley. Has run as low as 10.30's in a 2,300 lb. car. If you put too much cam in you kill low and mid-range power. The more displacement the engine has the more cam you can use. I believe the Thumper series uses more duration to give it a lumpy idle. Above idle it functions like any other after market cam.

I was looking at dyno results on the Comp Cams site. In a 358 sbc the 268 cam made more horsepower than the 274 cam at 2,500 rpm. The 274 cam didn't pass the smaller cam till about 5,000 rpm.

Picking a camshaft is both exciting and confusing. Have fun.

Thanks for the info.

I wish I had a 406. I would be more comfortable about these heads. Some people say they will make the motor lazy down low all by themselves. 50 more cubes would help. The people who say Sportsman II heads do fine, all have 500 hp motors. I'm concerned a 350 hp motor may be a pig.
 
I've got a set of 200cc Dart Iron Eagle heads on the 406 sbc mentioned above (in the Crosley).They are comparable to the World heads you have.
My Anglia has a 355 sbc with Sportsman II heads. Less than 200cc. Can't remember if they are 170 or 180cc. Had a .456/.456 Crane cam in it. It ran good but I never really got on it. Now has an Edelbrock cam that is even smaller. Just putting it together so I can't say how it will perform. I don't drive anything hard on the street.
You will probably lose some intake port velocity which will affect low rpm performance. How much I couldn't guess. But, if I was in your position I'd use them.
