347 Users..How Do you Like it?

Since having the 347, I wouldnt go with another motor. It made almost 400/400 at the wheels on the motor and ran 11.99 @ 117mph with no nitrous. On a 100 shot it went 11.56 @ 124mph and I drove it home 90 miles from the track. I drive it everyday and there are no cooling problems, only traction problems

24's arent enough for a 400rwhp 347. 30's at least. You can make awesome power with a 347 and still be fine on the street everyday if done right.

Im planning a 10.7:1 347 in the near future. Ported TW heads, TFS R or victor 5.0 intake, jay allen custom grind cam, 1 3/4" longtubes, 75mm TB, 30's, 80mm pro m. Might get a fms rev extender and bump the limiter to 6500. Easy 120 traps and low 11's. Im doing it right, im not gonna put marginal 302 parts on a 347 and expect to be happy. I'll be using the CHP rotating assembly-cast crank, forged 5.315" rods and forged probe pistons. Goal is over 400rwhp. Still havent decided how radical I wanna go.

Sounds good Dave...What size injectors do you run? I was hoping to get away with my 24 pound injectors and a chip, but will change if I must. Those sound like awsome #'s you got out of yours. PS I'd also want something that could make it cross country if I wanted to without any problems. Basically I want it to be as close to factory reliable as possible. It'd see mainly street use, with only the very occasional track session.

I run 30 pound injectors on my setup. They seem to be a perfect match running only at 50-60% duty cycle at WOT. As for going across country, I wouldnt think twice about taking mine on a road trip (well other than the no AC and windsheild wipers ) I have an Explorer for a daily driver now, but the Mustang was my daily driver for almost 5 years. My last 347 (Im on the 2nd one now) went for over 20,000 miles before it cracked from the water jacket to a stud hole (it could have been fixed but Id rather be safe than sorry) and thats with too many nitrous passes to count going thru that motor making over 500rwhp on the hose.

People are way too worried about running a stroker motor as a daily driver, there are too many rumors about oil starvation or just being unreliable in general. All false. If you treat your motor good and dont cut corners in your setup, they will go a long way.
