New Block Or Not?????

87prjctpony · 09-01-2005, 10:38 PM

Well Guys I Was Wondering If I Could Get My 302 Block With 188,000 Miles On It Machined And Bored Over??? Would It Be Worth It Or Should I Buy Me A New, And Bigger Block....???? What Size Should I Bore It Out To??? I Just Want A Good Shuvv When I Hit The Throtle! I Will Run It On The Track But I Will Also Need To Use It Almost Every Day.!

I'd keep the stock block and put a 331 stroker kit in it. If the engine has been maintained well, it should clean up at .030 over. Just boring it .030 over is not going to give you that shove you are asking for. But when you rebuild the engine and put a good top end on it, you will get that shove you are looking for.

Yeppers, IEC nailed it again. Even if you have to go .040" over, still not a big deal. Throw in that stroker crank, and you'll have a 333. That's what we have in our 2nd car, and it RIPS! 11.50's all day long.......

Heres what (I) do.

I take my blocks to the machine shop before I do anything.

Then they determine for me what it needs. Also what all the other parts need aswell.

Look at the ridge. That will give you a general idea of what the shop will want to do. When I buy blocks, I use that as a guidline.

It might need a hone, a bore or the garbage can. Let them figure it out.

Thanks For The Info Guys! I Might Just Stroke It Out To A 331 Or A 333. But Wats The Difference??? I Know That The 333 Os 2 Over Than The 331 But Does That Make A Difference???

Absolutely not! The difference is being bored .030 over or .040 over. You will never see the difference performance wise between an identical 331 and a 333. Maybe just a smidgen on a dyno but not on the ass dyno.
