Welcome to AFM!

First, have you already bought your stroker kit? If so, what brand?
Next, what has been done to your motor so far?

Red97 10-21-2010 09:36 PM

no i havent bought anything, the motor is stock aside from a few bolt ons

That brings up a few big issues. The main ones are the fact that the stock heads and stock intake manifold don't adequately feed 302 cubic inches, they will do an even poorer job feeding 331. The first thing you need to look at, whether or not you do go with a stroker, is a better upper end. Once you decide if, on top of a better upper end, a stroker is still in the budget, then you can decide on the specific components.

347/331, basically the same parts.

And please do not ask what one is better. Idk if I could handle another debate on what rod ratio is best.

if you are planning to stroke it go 347......

there is no replacement for displacement.......

but take in consideration all the components needed besides the engine to support a stroker motor......

IMHO - AFR 185cc heads, Edelbrock RPM II intake, and XE282HR would give you a well rounded - streetable - yet decent kick in the pants 331.

idk about that, ive heard of the 347's having issues using oil if used in a street car. Plus a 331 has a better rod ratio.....

lol :kooky:

The Myth Continues.....:head_shot:

Haven't we graduated from middle school yet fellas? Mature way instead of the "manure" way would be to present facts and let them speak for themselves. Further, look at "347 myth debunked" thread title. There's some maturity and humility there.

But how many times must 331 vs.347 manure be spread......

If the op would use a search engine the myth would be debunked.....

it just gets real old answering the same question....
over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over & over.......

the piston ring issue was engineered out of the 347 LONG AGO (in a galaxy far far away?)...or "one time at band camp, I heard 347s used oil"...
Stroker motors need big supporting mods = money....a good 306 can make 400 hp...make a budget and see what you can reasonably afford...as I often say you will probably be better off buying something already built than building your own.

God has this got old.......

BUT........

Those who can build.......

Those who can't buy......

And we all know what category you fall into.......

use of pink font is a subliminal message

What a joke......

Obviously, not everyone is aware of this and how it was corrected. If choosing to go the 347 route then go with the 5.315" rod to ensure the piston pin is located below the oil ring landing. There are still many kits on the market with the 5.4" rod with the piston pin intersecting the oil ring landing that perpetuate this galaxy far far away story - still to this day giving the 347 the bad rap in some camps.

At the same time, no one should be belittled for choosing a 331 either if they prefer to go that route.
