Big block virsis Small block
Big block virsis Small block
I know big blocks have all kinds of torque and power but has anyone ever actually raced a stock BB against a good running slightly modified SB in either a 1/8 or 1/4 mile . I've heard and I believe that it would be a lot closer race than some might think . ![poke :poke:](./images/smilies/1poke.gif)

Re: Big block vrsis Small block
I'd run a stock BB any day with my SB. The SB has more RPM's to work with.
Re: Big block vrsis Small block
My theory is if you take the weight to HP a 400 HP SB compared to the weight to HP of a BB combined with less wheel spin of the SB compared to a BB I think the SB would win the drag race but I have no statistical proof . That's why I'm asking if anyone has ever raced one against the other or knows the time comparison . I do realize in a rolling start the BB may have the advantage .

Re: Big block virsis Small block
I suggest that this be explored at the next gathering
Video wold be nice for those that cannot attend!

I'll race and go for the longest burnout with my sb

Re: Big block virsis Small block
I'd have to give the SB the nod...Little lighter , less wheel spin = better E.T's ..Randy..Jack you may have a PM

Re: Big block virsis Small block
Not sure anyone cares but a BB Trike will eat a small block for lunch. I've been on both sides of fence and
it's not even a close race.
Maybe the trike can put the power and torque to the pavement in a more efficient manner.

Re: Big block virsis Small block
I think a trike can better put the BB power the ground...Thus overcoming the extra weight disadvantage. And at least from my perspective .A big block bike is not a drag racer.But a burnout machine....Jack I just wanted to ask what series Falken you bought..Thanks Randy ![thanks :thanks:](./images/smilies/thanks.gif)

Re: Big block virsis Small block
I think a stock BB will beat a stock SB without any problem if they both have a skilled rider. If the SB isn't stock then all bets are off. I also agree with Randy that the BB isn't a drag racer but its a torque monster and will burn rubber at will.

Falken discontinued the XEIV or whatever it was called. I just put a Falken P25560R15 SN211 on my bike. I haven't had it on the freeway yet, but it seems fine, so farrandy burkey wrote:Jack I just wanted to ask what series Falken you bought..Thanks Randy

Ooops My bad..Sorry Jack..It was Carl that got the new tire..Thanks Carl..And hope your happy with it..
Re: Big block vs Small block
Guys I'm not qualified to talk about SB vs BB in a bike chassis - but if there is any comparison re. the same combinations in a car then ultimately a big block just has to out perform a small block in every respect - ie. alloy block BB is not significantly heavier than iron block SB. BB is perfectly capable of revving at least as well as a SB with the right heads. A BB will always have potentially better top end breathing owing to bigger bores and spacing, allowing larger valves. Of cause non of this top end stuff is really needed with a BB when built carefully for a wide torque spread. A BB 540+ cu in on a 4.50" or 4.60" bore just has to kill a small block - (provided sb normally aspirated - if not, all bets are off). The great leveller has to be traction (or lack of) - I'm guessing bike guys don't have the advantage of weight transfer off the line?

Re: Big block virsis Small block
If you are talking stock tires then it is really hard to race a BB and also probably a modified SB due to the wheel spin/traction loss...a willing passenger would be needed to gain the traction needed and those are few and far between..

yeah right..I can hear you now.."we are going for a really short ride...yep...just hop on the back..we are leaving the pits and going to the staging area...you will see a set of trees with lights..dont worry about the guy beside us...just watch the pretty lights go from red to yellow to green and then HOLD THE FUCK ON FOR THE NEXT 8 OR 9 SECONDS!"petitemoose wrote:Not really ... you simply don't tell them what's about to happenCanuckHoss wrote:If you are talking stock tires then it is really hard to race a BB and also probably a modified SB due to the wheel spin/traction loss...a willing passenger would be needed to gain the traction needed and those are few and far between..

Re: Big block vs Small block
BB has more of an advantage in a car because a car weighs more and takes more torque to move it. A SB revs quicker and in a bike that doesn't need much torque to move it due to the weight, the advantage of big cu inches is lessened. In my opinion a stock BB will always beat a stock SB with equally skilled riders in a Boss Hoss. The new stock LS engines in Boss Hoss bikes will beat a BB even though they are actually a small block. My V8 Chopper with a 350 SB ZZ4 will beat a stock Boss Hoss BB. I believe its due to less weight and a trans thats less parasitic.roscobbc wrote:Guys I'm not qualified to talk about SB vs BB in a bike chassis - but if there is any comparison re. the same combinations in a car then ultimately a big block just has to out perform a small block in every respect - ie. alloy block BB is not significantly heavier than iron block SB.
