I am planning on building a supercharged 331 or 347. The problem is, I don't know which one to get. This motor will be efi and in a daily driver car. I keep on hearing that 347's burn oil. Is this true? </P>
Which stroker kit should I get? 331 or 347?</P>
Thanks.</P>

problems with the 347 are that they dont seem to last that long. to much stress on a stock block. maybe if you bought a 'R' block there wouldnt be such a large problem.
but remember any motor built wrong will have issues

o yea if your car doesent break ur not driving it like u should
I am getting an R-Block, but i have called a couple of places near me and 2 of them said go for a 331 and the other one said go for a 347. I think i am jus going to go with a 331.</P>
if you have a stronger block then go with the 347. but since you are chargin it you might have too much compression and blow it up. go 331 <IMG src=smileys/smiley2.gif border="0">
I was told the rods on the 347 have been failing...
</P>
different kits have different rods. what kit are u talkin bout, the ford racing??i wouldnt get that anyway, i would make my own . trick flow crank & pistons, eagle rods, Speed Pro bearings, sealed power oil pump, ARP bolts<IMG src=smileys/smiley2.gif border="0">btw you can get all that at www.summitracing.com </P>

347 kit do not burn oil any more unless you get an old set up. must use 5.315 rods www.speedomotive.com . they make kits for forced induction/low compression.<edited><editID>619socalstang</editID><editDate>38012.7375347222</editDate></edited>
