Cam recommendations for TPI.....
What would be the cam recommendations for this Tuned Port setup, it would be a daily driver, looking for around 350hp and have decent gas mileage, but respectable power.
Build up includes:
ZZ4 short block
Sportsman 200 angle plug heads with 64cc chambers
Stock '92 TPI ported intake/plenum.
Doug Thorley headers and cat back
*
A TPI specific cam
Oh yea, this is going into a truck.

The camshaft I run is a specially designed Lingenfelter profile for TPI engines, and would suite your needs very well.

After reafding various posts for the last 3 hours, I think I've decided on the ZZ4 cam.
I will not be exceeding 5000rpms as this will not be going to the track but will be passing alot of cars on the freeway, so I don't need the added breathing over 5k, usually no more than 3500-4k rpms.
The ZZ4 looks very streetable yet still have plenty of low to mid torque with the stock TPI intake.
Any different opinions??

You are planning to put that camshaft in a street driven 350 TPI car ?
The only way I see it working well is if you keep the nitrous flowing full time.
That is a racing cam.

That Lunati full roller seems pretty hairy for a TPI. The dur @ .050 seems excessive, and a 112+ LSA might be better than the 110 LSA because it will provide more intake vacume. I got a Comp Xtreme Energy HR w/ 218/224, .495/.503, and 112 LSA, and some people were telling me that that was too big for what my engine.

excactly. It's much more radical than the cam I run in my 383.

It is an extremely mild cam that builds great cylinder pressure.
