Looking at buying a stroker kit sometime soon and I'm not sure if I should get a 347 or a 331? My car is not a daily driver. I will probably go with a set of AFR 185's, Track Heat Intake, 70 mm TB, 30lb squiters. What is the better stroker? I hear from some people that the 347's had oil problems.

 

yeah, i think the oil probs where mostly when the kits first started apearing. nowadays you rearly hear of it. A bud has a 331, afrs 185s, Cobra intake and a few other thing and it works real good!

the pages doesnt work

 

hmm.still works for me, but it might have exceeded bandwidth. try again later

 

mm&ff just did an interview or something with D.S.S. or C.H.P. or some place like that. The guy actually said it was better to go with a 331, they in fact make more HP, have less internal stress do to the way the rod connects with the crank, etc. etc.

I'd go with a 331

 

I went the 331 route only because I got a super buy on the kit off ebay. If i did it again i would definatley go with a 347. If you are buying the kit new they are the same price. Its simple math , more cubes, more power. The oiling issue was in the very first kits to come out because the piston pin intersected the oil ring, but that has been fixed years ago but the internet myth about it lives on. Definately go 347.

 

Thanks for your replies guys.

 

1 more for the 347. I've seen 2 cars around Burlington with over 20,000 km's on them and running strong.. no oil burning.

 

Syntetic OIL !!!

 

One of them runs Shell Rotella 15W40.
I ran that on my old mustang with over 300,000kms and it ran strong though e-tests and the drag strip.
