hey guys i have a question. im looking to get a short block and make a 331 stroker over the winter. some guy made me an awsome offer on one but its a non High output motor. would it make any deffrence if i made the 331 from a h.o block or non h.o. block? thanks

why 331.. why not 347?

and you better not say... "because 347 strokers burn oil"

my dad was saying 347 but i was told boring out a 302 and stroking to 347 wouldnt hold up and perform to its full potential and that a 331 is perfect. im still considering the 347 but then arises my question does it make a deffrence if i bore out a h.o motor or non h.o.

He is a wise man.

thats BULL****... the only reason to build a 331 is if you have a cubic inch limit for a race class.. or if you just dont want to make as much power...
347 > 331... always

the blocks are the same, so long as you get a roller..

ok yea cause i always wanted to build a 347 but some guy was tellin me it wouldnt be right but im going to look into it. only problem is i dont want to run a carb system.

lol, all you'll need is the proper bolt ons which includes upgrading fuel system and a tune, and 347 won't be a problem, totally streetable. Adder know his ****, at least that's what I see on this site. I'm gonna have a shop build up a 347 short block for me and then I'll do the rest. Stroker motor will require making clearance to the block for the internals.

I'm building a 331 just because it drives Adder nuts!

Oh, and I heard 347's burn oil and don't last as long!!! LOL

oh dont forget the rod ratio's

AdderMk2

no, your building a 331 because your a little girl who fears cubic inches

lol adder u make me laugh.
and op, just go 347
a while ago 347 did burn oil and werent that dependable.
but times have changed and its the same thing as a 331 only with more *****.
