So I'm finally coming home from college in a couple weeks, and I can get to work on putting together the .030 over 4 bolt main 350 that's been wrapped up in my garage for the past 3 months. I think I got everything together, but still have a few questions.
Should I reuse the intake manifold and front accessories on my 305, or just use the 350 stuff? I have the wiring harness and ecu that were on the motor, or does it not make a difference?
Whats a good cam to use for this motor? I'm still debating on whether to use the 350 crank, or buy a new 400 crank, plus I'll be adding vortec heads and intake in the future, so I'd like a cam that can accommodate those but be usable with the stock ones for now. Also, roller, or flat tappet?
And lastly, when it's all done, should I keep the EGR system operational or not? I live in PA, no emissions testing, but I hear that it robs power from the motor. Plus I was going to add some headers, without the EGR it would give me a greater selection.

 

If you kill the EGR system, youll have to have it tuned out of your PROM, is use the 305 acc. but the wiring harnesses will be the same, just use the 350 computer, cam should be a a hydraulic roller, dont downgrade to flat tappet, keep in mind the increased airflow and bigger cam, will require some serious tuning, and unless you can do it yourself, it can be quite pricey to pay someone else to do it. i dont think the 305-350 intakes are any different in stock form, but im not sure. if anything, buy a aftermarket 4-bbl intake, and get a TBI adapter plate, since your planning on eliminating EGR anyway.
