Judging from this post, it's obvious that you need to put your combination selection in the hands of an experienced engine builder.

To answer your question, I wouldn't even use that size cam in the 408's I build, much less a 347ci motor.

Daaaayum!
Insane duration figures for such a cubically inched challenged engine. That's a lot of cam. Sounds like you are building a track only engine...

That should make good power around 8000+ rpm's. Of course, the intake manifold unless you are running a super vic will run out of breath long before then.

If you can get that cam to run in a 347 please let us know.

You may want to think of going solid roller at this point. I bet you have to run 101 octane after that setup.

That is almost as big as the cam in our 454!

Way too big for a 347. Plus with your heads milled as much as they are, you would need massive flycutting.

tht was the previous setup was, drove like stock, even when untuned and no stall, no surging, pushing thru bakes, ect.

yea, thats giant.

give us info on your setup, what you're planning on doing with the car, weight, gear, converter, etc.

maybe in a solid roller with more compression...also a ported victor...I won't mind giving it a try...but I would have light weight valve train and have to spin the **** out of it... still would probably stay on the 250s

my 239/243 made nice power for the ported fast I have...pretty close to the same setup but I have stock bottom end, flycut and 215 TFS, right around 11.9 to 1

put 485 rwhp through a locked a4, 4.10 12 bolt
