I hope you talking about a modified big block. I don't think a stock B,RB, or Hemi can even run with a reasonably built 4" crank smallblock.



We need a Ricky Recardo smiley cause that's simply ridiculous, lol.



Lets keep this simple.. a stock 440 4bbl makes about 375 hp??? My lil ole 390 stroker makes around 450hp... this is at the crank. Stock 440 uses exhaust manifolds, stock intake etc.. I think my 83 cordoba 390 would wail on just about any stock 440 thrown my way. Granted, I have nice headers, ported heads, cam etc, but when I said it pulls like a big block that is what I am comparing it to.

Steve Dulcich made 425 HP with a stock stroke 318 using the same EQ magnum heads I used. They ported theirs to flow 270Intake at .500 lift and 219 at .500 on the exhaust side.

Here is what he had to say about bore shrouding....

""A 318's bore is too small!" Tell it to the even smaller-bore LS1 guys. "The 318 was never a high-performance engine." Maybe true, but we'll show you how to make it one!"

What is the stock bore of an LS1? 3.900?????

Is the 318 a performance engine? No... can it be built into a performance engine? Of course. Is a 340 or 360 a better foundation for a performance build? Sure it is, but if all you have is a 318 that is still a great perfomance engine waiting to be built. I have a late model magnum 5.2 in my Grand Cherokee that will be getting the full 390 treatment soon. Could I have got a used 5.9 block to build? Yes, but why spend the money for an extra 20-25 HP when I have the 5.2 block already. Not worth it to me.

Here is a peek of what a 71 Olds cutlass 455 got to see when I was at the strip and still could not make a clean pass..... 13.75 @102 without hitting 3rd gear. TBF
