I'm a big block guy, all day long.
But, my 62 Valiant doesn't lend itself to a BBM installation easily, so I was forced to build a 428 small block street engine 615HP, 540 TQ, and a 10.49 best without much tuning so far.
I've had plenty of 440s, built cheaper, that ran about the same NA.
The difference is, I can put two kits on the 440 and run 8's.
Not gonna get there with the small block!!!!

One question has been haunting me for sometime now.....
Who needs a big block when your small block stroker makes 660 + ponies ?
Does a big block will make you go faster in the same body with more torque ?
I see here big block builds hoping to get 600-650 hp and go fast....faster than my 606 hp small block ? should I go big block to get better et's ?
I'm confused.....................
Dan
best 60ft 1.30
best 1/8 mile so far 6.40 sec
.
You consider running a 640 with that 130 60 foot fast? Maybe you should consider a big block and run some better times after all you said race car

I'd believe that theory..... but I've seen what the Belvedere runs.... 
It's fun to have a lil block again!

No you're absolutely right.... the engine in my Mirada was a prime example. Mild port Stage VI, 4500 M1 intake with Ebay dominator (old carb shop piece... I should have kept it!), stock block, stock LY rods (Moparbilly beta tested LY's to the 8's on spray so I wasn't worried about mine  ), stock crank welded and cut to 4.15, stock main caps with ARP studs, off the shelf Ross pistons, UD640 mech cam, no hardblock, freshened 4 times and was pretty much used up at the last one.... ran 9.93's on a string the last time I ran the car in 2012. Wore out bullet is STILL in the car two owners later..... but it was a yawner shifting at 5800, trapping at a little over 6k. I don't have the receipts anymore, but it wasn't as "cheap" as moparbilly stated, but it worked.... for a long time. ......but the small block has brought back the "fun" for me!

I understand that a big block will make as much pôwer as a stroked small block, only cheaper....
My Indy headed small block cost me over 12k, and I've gone 10.30 in a 3100lbs car, normally aspirated without nitrous.....
From there I'm left with either take as much weight off, or go big block to run high nines.
If every 100lbs lost is 0.1 sec faster, I put the same engine in a 2500lbs car, I should run 9.7 or so....again without nitrous......
After all that thinking, do you really need a big block to go fast ?
Give me your thoughts

A 400 block, built with B1 heads and a 4.15 stroke or close to that can make 850 hp . If you need more, up to 1050 hp with the right combo with B1 heads. For a somewhat streetable combo, it will be tough to beat 604 cubes, about as big as a BB can go. There are some good heads for small blocks, but they just can't be built big enough

I also notice some of these smallblock strokers are bigblock (400 plus) cubes and are a lighter eng. So as Bill Jenkins proved when his lighter smallblock Vega ran right with the hemi's its all about HP to weight. I agree that alot of times the bigblock can be cheaper to build to get the torque. I dont think a smallblock of the same cubes as my bigblock would ran as fast in my heavy B-body and to me a 63 Sport Fury from the Max Wedge era just looks right with a bigblock. But I am very impresed how strong these smallblock stroker Mopars are running. Ron

Our stock block 340 based 4" stroke W5 mill went 9.8's and that was still at a conservative shift point.... my dad shifted it at less than 6K and usually ran 10 ohs. Car was nowhere close to legal for 9's. I really believe if he'd "let her eat".... it would have gone deeper than that.
we're currently running a fairly mild W8 4" stroke combo and went 9.64 last weekend with the shift light set at 6600. We're just starting to have fun! I've always loved small blocks and as I stated earlier.... we B havin FUN!

Why not ? Mine went 5.60 w a 150 tune,that's 8.80s.I shift at 7000 and it's w 20yr old indy heads.A stock 340 block IMO is also ALOT stronger then 440 blocks as they have a tendency to blow near the pan rail or split from what I've seen of the 3 blown 440 blocks in low hp mopars.
A 400 block and B1s would be a good one I think,but NOT a 440 block.

In the end, it boils down to preference. A maxed out small block with tunnelram, best block and heads, 400+ cubes, will no doubt be fast, a big block will be faster, simply because it can be built bigger, and has a bigger bore. So it boils down to budget and preference. A good reference point would be a comp class, or sprint cars, how much power do they make? At what cost? There is something attractive about either engine family. Personally, I am a bigblock guy, ever since I walked away (unintentionally)from a stop light in third gear in a 383 four speed car in 1970. That amazed me, and set my preference pretty much in stone. But that is me. Somebody out there no doubt had a high winding small block, kicked butt on a few BB cars, and fell in love with it, cementing his preference.

same short block.... different set of heads. #3 rod let go.... It was also #3 intake runner on the leaky heads that kept introducing water to that cylinder. Believe the rod got damaged and it wasn't caught until it was too late.

It's all about one thing for me, cost! I raced 340's for years, nothing expensive, only ran high 11's. When I bought my first backhalved roller in 2003 I found a 451 short block for 2 grand from a well known racer, added $1200 Eddy heads, M1 intake and the old 590 purpleshaft cam which was $169 and came with lifters! I went easy 10.20's and 2 yrs later was running easy 9.80's at low RPM. I love small blocks but I won't get back into them until I have extra cash as I know I'd have to spend alot more on it to run that quick in a pump gas street car. My current Duster will never see a track but I found a great deal on a stroker kit so it is 500 inches with Eddy heads, I have very little money in it, can blow the tires off with ease, and I can run 3.55 gears and a tight converter because of all the torque.

Sounds like a fun car and that's what it's all about. I'm a SB guy and a semi-reformed rpm junkie, but I really would like to have a 500incher in a mid 60's B body.
Yeah, it's got a smallblock.

I love my small blocks. I went 9.90 na at 3300 lbs with a stock block 4 inch crank and Indy 360-1. That was 12.5 to 1 motor so I ran it mixed pump and race fuel. Now I upgraded to a R block and go 9.43 na at 3195 on pump gas. I add a single stage plate to her and she will run 8.56@162. I only shift it at 7000 so I dont think its a high manteince motor, same valve springs last four year and still pull the same. I loved racing 10.0 index with it two years ago, I would shift it at 5500. Think it would have lived a long time running that class but I built it to go faster.
