I remember I had build up a pretty good 350 for my 69 chevelle, and I bought a 67 SS 396 Chevelle not to long after I got the 69 done. My buddy drove my small block car home and I drove my "new" 396 home and outran what I thougt was a pretty decent small block. THe 396 was a bone stock 325hp motor. It was close but the 396 was faster. I was a BBC guy after that. I spent a fair amount building the 350 and then a bone stock 396 was faster? That was all I needed!

Anyways,, I think its the torque that impresses everyone that drives a BBC. And I think that torque is what makes up for the rpms. I had a friend that had a high winding small block and yes he ran fast but at 10000+ rpm. It was a 5spd car and it was wicked low 10 second car. I ran high tens and low 11's with not much of a 427 we built for the chevelle and it didn't have the chassis that he did or transmission at that time.

If Size doesn't matter then why are all the small blocks trying to be big blocks these days? Why not just run a 350 or smaller and call it good? A 454 small block? Not very small...these big inch small blocks are impressive though. It all comes down to what you like, and what your budget allows. I think you can get there easier with the BBC. I like them both, just have been a BBC guy for a long time.

Peace out...


Oh WHILE YOUR ON THE SBC CI..i just heard that Sonny's is Coming out with small block 500 ci or a little over..i will get the info on it and pass ..i heard this ....and thought for a minute..but realized this was probably the case NOWADAYS....

With all the hype about small vs big inch mtr. I dialed up Self racing last thursday about their Brodix clone 18 degree heads that have an advertised flow of 420CFM (brodixs flow #'s are 383(CFM) both being fully CNC ported. Self racing sells their heads ready to race with .750 lift roller spings for $3500.00 and a matching manifold for $1000.00. The reason i called them was to get a comparison between my brodix 10rp's which flow 314CFM at .700. i was told that it would be 75 and 125 HP difference. that's a lot of improvment over 23 degree heads. I'm thinking maybe with my current setup (434") it will have close to 750HP on alcohol. If i had the money i would make the switch even having to replace the pistons and rebalance. That's a lot of gain when you consider what it cost to get the HP above 700 in in a s/blk and you wouldn't have to spin it above 7500 RPM.

In my experience, small blocks are best for decent power while salvaging some fuel mileage. Or even some big power if you are willing to deal with the expense and maintenance associated with a 7500+ RPM motor. As for all out power, you simply cannot beat a big block. In my opinion, in a street strip weekend car, an oval port 496 is just too easy and cheap to spend the extra time and money trying to make the same power with a small block.

you can tell real mechanics by the big block numbers they get out of a small block.

Timmyboy86 08-27-2007 01:22 AM

if your shotting for over 500 hp or ever plan on having over 500 then go big block i made that mistake and cus myself everday if i only put 250 ontop of what i'm invested now i'd have a 600+ hp bigblock but instead i'm running a 500-550 hp small block.

billhendren 08-27-2007 05:27 AM

With the new Dart 4.5 bore spacing small block its easy to get over 550 cu.in,all it takes is $$$$$$$$$ Bill

chevguy65 08-27-2007 06:39 AM

Big Blocks are great, no doubt about it....what is even greater is driving around a BB car and putting him on the trailer and watching him go home after getting spanked by a lil ole SB :P :P :P

doubler 08-27-2007 09:10 AM

Bill, what happens to the size of the block at 550? I went to darts site and here is the race block specs...you can get 455 with this. Do you use the aluminum block to get 500 or is this a totally new block? Must be...HOw big is the bore on these new blokcs? I can see some advantages to this, lighter, power to weight etc. Anyway disavantages with the newer blocks?

BBC have to go to these much taller decks to get it, 11.1 deck...any new blocks for the BBC coming out to keep up with the "small motor"

However big you can make a small block, you can always make a big block way bigger using similar after market blocks. Plus, the big problem is not simply the size with the small block, it is more the fact that big block heads flow so much more air. I think the highest flowing small block heads are the Dart little Chief heads or SB 2.2 at around 450cfm (or around 330 cfm for a SBC conventional head and a stock oval port BBC head flows that with a little porting and big valves). A conventional after market ported big block head is capable of flowing almost that. If you get into exotic BBC heads, you are looking at ~600 cfm. For what it would cost to build a little chief headed 550cid motor, you could probably build a 600+ cid big block with big chief heads and probably make another 100-200 hp. Along with being more powerful the big block would most likely also be stronger due to the shear size difference of the parts.

Here is what you can expect between with a conventional Headed big block and a conventional small block in a racing application:

Big block:

Small block:
http://www.shafiroff.com/sportsman/434_685.asp


Here is a big chief combo:

Here is what is capable with a big block and a dart big M block and pro stock heads.
http://www.sonnysracingengines.com/p...632-1320hp.htm

Or if you want to really go all out, this
http://www.sonnysracingengines.com/p...es/811hemi.htm

Sure, you are talking $75,000 but you simply cannot make this power with an N/A small block regardless of the money.

The most I have heard out of an N/A small block in any configuration is ~1100 hp

Here is a good comparison between the best of both that the small block and big block worlds have to offer as far as heads go.

Hey not fair, she can't vote, same ISP. I know how to vote more because i'm a computer hack, but i'm too honest to change an honest vote. I would have hoped that s/blk would win but the true message here is that b/blks are easier to build and make more HP for the $. I don't feel bad that b/blks are and will win. But i would love to see you b/blk fans when a s/blk motor puts you on the trailer and it does sometimes happen.

I am not eligible to vote.

I am a Big Block Chevy Freak. I build more Small Block Chevys.

I guess I do still build more Big Block Chevys than anthing else though. Fords, Mopars, Pontiacs, Olds, and little stuff both foreign and domestic all comes through here at one time or another though.

Not that any of the others matter in this poll.
