I'm in the middle of picking parts for my 347 and I'm wondering which manifold you guys would recommend? Is the victor too radical?
The victor is one of the best intakes out there for a nice 347 thats gonna see a bit more rev's (under 7000) Just be sure the ports match and mill the intake as needed to fit. The little BS involved with the victor intake is what caused me to not use it. I went with the slightly smaller tfs-R since its more of a direct fit. I would have rather used the victor but its too involved. No egr, no pcv (gotta rig it up) may need milling to fit heads and ports are larger than some heads and the heads will need port matching. Thats what turned me off. To answer your question, absolutly NOT is it too much. Your building a 347, not a 289
Well I've already gotten rid of my pcv so that's all good. How does it have an affect on egr when thats on the throttle body?
Egr goes from ports in the head up through a port in the manifold and into the egr spacer and egr valve. Then when the egr valve opens it puts egr back into the manifold. Why did you ditch your pcv, are you running an evac set up?
I'm not trying to be an ass or offend you when I say this... If you have to ask if a Victor is "too big," you shouldn't be using it. Because of it's short runners, cam timing is critical. There is tons of airspeed in a long(er) runner manifold such as a Holley or RPM II (as Rob mentioned). There is not "tons" of airspeed with a Victor - it needs to be "created" with cam timing. For a regular old hydraulic roller street 347, the Holley or RPM II is plenty, and much more friendly towards different company's OTS cams. Joe
That IS a pretty importan factor to mention. I do think though that anyone who is getting a 347 built and doesnt spend $100 more for a custom grind is...........(you fill in the blank) RC
I'm definitely planning on a custom cam, but I have to get everything together first before they grind a cam. Does anybody think that paying 1800 for shortblock assembly is too much?
