How would you rate the result relative to the effort and relative to flat tappet cam engines?
What are some of your other specs? Comp ratio, chamber cc, carb?
I'm really interested in the exhaust system you've chosen. Can you tell me what you chose and how it sounds. My 327 is going in a Porsche 911, and not much distance to work with there but I don't want a really load sound.
Happy so far, Is your 911 RearEng?
The 1st time RamJet350cam= ((intake/exhaust) is 288/308; dur @ .050" (intk/exhst) is 196/206 lift (intk/exhst) is 431/451. lobe c/l 109 degrees)) was alot more time consuming. Mainly just cautious clearancing for the guides. It's 72ChevyC10 Trk, SBC350,THM2004R,12Bolt3.73,9.0-1 Comp.Ratio mostly stock, Performer carb/intake/dualExhst very smooth runnnig,15,000mi so far. The stock cam was about same Dur. W/less lift. 2 MPG more & little more HP.

Haven't Quite finished it. Thinking about swapping RamJet cam forZZ4 & getting larger cam for 406. ZZ4 is way to small for the 406 with my heads.
I've got a few other tips #1- A guy in Fl. Mounted his Spider using the holddown springs from a lifter valley baffle tray instead of bolts/studs. I haven't tried this but he said no worries.
#2- Go to www.gmperformanceparts.com
& search for Part#88958652 "Quick Cam" ValveLifterGuide this is (Very) nice for swapping cams without removing intake or lifters!! or /www.gmpartsdirect.com you have to download a 30MB catalog to see a Pic of it a the first site.
