347 or 331 ?

[Mnirishjr]

Not a stock block...

That would of been nice to know... and now knowing you really cant compare your current setup to the OP's concern.

 

[Mnirishjr]

Actually my 331 is better than other 331's cause its really a 332

I still say stroked 351... but if you build a 331 or 347 put big heads on it. AFR 205's etc, AFR 185's and TW 190's imo limit a stroked 302. Assuming you have the cam to boot.

You got this all figured out huh?

The block has no effect on the ring package and the old school blow by problems. LOL


I feel like Im on the Corral.

No shit Sherlock... The op's concern was reliably issues w a stock block. Re-read his initial post. So your 8000 rpm animal cracker don't relate.

Youre killing me. Im literally laughing.

Read the op

"I'm thinking of building stroker for my drag car, and I'm looking for opinions from people with experience with stroker 5.0 based engines. As I understand it, the 331 keeps the rings slightly lower, reduces blow by, and keeps the rings out of the wrist pin."

Im talking about ring and oil control issues, not hp issues. Stock blocks are grenades with power. Nobody is disputing that.

Youre argument that .15" of stroke is the difference between having blowby and not, and cracking and not, holds NO water.

 

[Mnirishjr]

Would that kind of compression split a stock block. It is a early block (1969) which would give me an avantage. I figure that if I keep the rpm lower, shifting at 6500, would keep it together.

You compared your motor to the topic. My point is YOU CAN'T! Did you not say "I spin my 347 to 7500 like its going out of style". But left out that it is a dart or sportsman block.

I'm done filling this thread w rants.

The second time, I did it right. 3.40 stroke for me..... "oh and that 'rod angle past 6000k" statement.... Well I shift over 7500 with the 3.40 stroke engine and its STILL pulling.

TADAA

Rest my case....

I can actually. Im comparing a 3.25 stroke engine to a 3.40 stroke 8.2 deck engine because (wait for it) Ive had both. I am NOT comparing the hp capabilities of the blocks

Again, the stroke and ring package are NOT relevant. It is NOT the difference between life and death in these engines regardless of the rpm range utilized.

wouldnt waste my time lol

Thanks for all of the replies. That's why I like this forum. Lot's of information, and none of the B.S.

Now look at what you started, These guys have stroke issues :gay:

Holy hell, I didn't want to start a war. All I want to do is rebuild my 302 block that I built in 1993, and still beating the snot out of today. I don't have the funds to complete the 521 big block for a while (no need for a aftermarket block, or a 351) I figured that since the 302 desperately needs a freshening up at the end of this season, I'd dump a stroker rotating assembly in it. Which one would you guys with experience recommend, I heard stories, read unflattering characteristics about, bla bla bla, are they true? Thanks to everyone that provided me with the right place, and people to contact. Also, thanks for sharing your hard earned and expensive lessons that you learned. I'm sorry that I lit the fuse on this one.
