what maxed out about a 3.4 stroke and a 4.030 bored motor???

Exactly. I'm sure we will here things like "rod ratio" and "piston side load" and "wrist pin intersecting the oil ring". I can't wait to learn why a 331 is a better choice than a 347 and I really can't wait to learn why a 347 isn't reliable and why it will burn oil.

I've also seen rebuilt 302/306's last maybe 5k miles, and i've seen stroked motors run for years and years of daily abuse.

It's all about how hard you run it and how WELL it's put together.

I have built a hand full of stroker motors and ran with friends, 331 and 347 on street and track.Also Certified Ford gas engine technician. 347 is not an ideal street motor due to rapid wear on the rings (from the relatively low rod ratio) and increased oil burning.331 rod ratio is closer to stock 302 ratio. 331 is a better street engine.Since you don't think I should be talking maybe I should sign off and let you crack yourself up.

I knew the rod ratio bullshit would come up. Hmmm, lets discuss this for a bit. Why is it that rod ratios apply only to the 347 and not to anything else? The Chevy 400 which was used in thousands of cars and trucks over the years and lasts well over 100,000 miles with CAST pistons has a 1.48 rod to stroke ratio. A 347 has a 1.59 rod to stroke ratio. The Ford 5.4L has a 1.59 rod to stroke ratio. The Chevy 454 and the 502 have a 1.53 rod to stroke ratio. Honda 4 cylinders have a 1.58 rod to stroke ratio. The Pontiac 455 has a 1.57 rod to stroke ratio. Toyota makes some of the most reliable engines on the road with 1.57 rod to stroke ratios. A 408 uses a 1.55 rod ratio. Do 408s wear rings out and burn oil too? Rod ratios mean nothing. You can take that to the bank. There is no rapid ring wear in 347s or any of the other engines I listed above. That is 100% bullshit. Show me a 347 that burns oil. That's great if you've built a handful of stroker motors with friends. That doesn't make you an expert in the field. Talking about rod ratios and oil burning confirms that. I've built and owned several handfuls. None of them ever burned a drop of oil and none of them were unreliable. All of them were daily driven. Come to think of it, I've never talked to anyone that has ever had a 347 burn oil or have any issues. But I have run into alot of internet experts that preach this oil burning and rod ratio bullshit.

Say wa..you serious?

LXpat93 · July 7th, 2009, 01:10 AM

yeah im serious the 331 may be better supercharged than the 347 of vice versa.

93mustank · July 7th, 2009, 01:15 AM

What do you think would respond better?

LXpat93 · July 7th, 2009, 01:21 AM

idk i was thinking a 347 then i saw that one dudes times and was like wow either he built it like shit or its just not the motor to be supercharging thats why im asking you guys from what you say you seem to know your shit.

93mustank · July 7th, 2009, 01:23 AM

Your first thought was right......

Dont run a 331 when you can run a 347 for the same price.....

The name of the game is money..... but examples out there show otherwise.

e3sean · July 7th, 2009, 01:25 AM

ive said it before and ill say it again....

my quote bitches dont steal it as your own!!!

The great E3Sean once said:
The only thing you will be burning when choosing a 347 over a 331 is the guy driving the 331!

my 347 burns no oil and i drive it nearly every day. i drive it an hour across town in 110* weather i drive it down the track 10 passes a night on a 125 shot... no problems...
