if i had the choice, 100% big block, biggest you can get in CID also. Big cubic inches makes a street engine with massive torque, good driveability and very nice HP.

depends on what you want it to do. I like the small block because it drops a bit of weight off the nose for possibly better cornering. Big block can't be beat for all out accelleration though.

Big Block all the way, I have built a couple small blocks before, don't waste your time, you will regret it, nothing beats a big block, once you drive one you will never go back

You've got to decide for yourself!! What do you want to do with your car? Drag race it? Weekend cruises? Daily driver? All of the above? Don't go BB because someone says "drive one you will never go back" (sorry cody if you hadn't said it I would have still used it http://www.camaros.net/forum/smile.gif ) BBs will be easier to make power but also are a little more expensive. If you like cornering a BB requires more suspension in the front to offset the extra weight, more money! And you're car didn't come with a BB so don't forget there's added cost to convert it to one.

You may avoid driving a BB because the cost at the pump is putting a pinch on your pocket! Our average club cruise sees the BB guys filling up 2 times to the 1 tank a SB uses... There's that money thing again!!

Don't read me wrong, if you can afford it, cubic inches is a good thing http://www.camaros.net/forum/biggrin.gif If you have to budget and only do half the events and outing you would really like too, then maybe a SB is a better choice!! After all what good is it if you can't use it!! http://www.camaros.net/forum/biggrin.gif

c4boom - I think you meant the 400 has a 3.75" stroke http://www.camaros.net/forum/wink.gif

no offense taken. But it all depends on what you are doing with your car, for a weekend car/ slash drag strip car and if you want a lot of power, get a big block, might as well spend a little more and do it right the first time, if you are building a daily driver then a big block might not be the right choice, there is only so much you can do to a small block, also why not be a little different, any chevy engine is going to be common but everyyyyonnne has a 350

no 400 block with a large journal 283 crank http://www.camaros.net/forum/smile.gif sorry for the confusion

yeah but everyone builds there 350's different. i'm going with a SBC becuase of how much money i have to spend. if it wasnt about the money i'd go with a torqey Big Block, becuase a mild street big block will stomp a build small block, besides the fact that you can use lower gears and still take off quick.

Check me out b/c I've posted before what my combination is, but I only have about $3800/$4000 in my 496!!

Heck, I have $2500 in my 406 SB that I built back in 1983.

Remember, only cubic money beats cubic inches!! LOL. pdq67

PS., and I have a soft spot in my heart for the early, little engines!! 265 to 327.

Or......You could build a 6 inch rod 383 or 406 and have the best of both worlds. It's pretty easy to make 500+ ft. lbs. and 500 streetable HP with those engines.

Yes, but lets go above that level! Say, to the 650 level.

The BB will do it alot cheaper then the SB.

I really don't think that a 500hp SB is really a daily driver, here. Of course, you would have to be stretching it to call a BB at this power level a daily driver, too.

And if you want light, just put it on a diet w/ al. heads, w/p and intake and ditch the cast-iron exhaust manifolds for some headers. Imho. pdq67

I'm all for kicking it up a notch, I was just making the point that if his car is already set up for a SB he could attain BB numbers w/ the engines I posted. I also believe you can build a daily driven 500 HP 383 or 406, I will admit it won't be cheap though! I guess it depends on what a person considers daily driver material. Lingenfelter built a 660 HP 496 w/ 10:1 and a hyd. roller that I thought was really streetable, but again, It's not going to be cheap. I was just trying to illustrate that a "best of both worlds" is possible between SB and BB. He never said this was going to be a daily driver, and all I said is that 500 HP can be streetable. http://www.camaros.net/forum/smile.gif

Right-on, Ratmotr. I concur whole-heartedly.

I just gotta,, but please don't feel bad when the infamous "more power, Scottie" bug bites you!

Oh, I forgot, there's always a "lung" transplant! pdq67

pdq, it's funny you mention "lung transplant". I had a 6-71 and it was slated for a SB to go in my car, but I looked at the big picture an decided to trade it for part of the combo that's now going in. You have what I want to end up with, a 496. I've been told by several people that the 1/4 inch arm is where it's at.

I've always had S/B engines and this past project I put a B/B in a 69. Yes, the B/B are more fun but as DJD said the B/B are more expensive to build or buy outright, and more for up keep(gas and all). If you can afford to built or buy the B/B.....Go for it. If you are on a tight budget don't overextend your self and go with the s/b. You can do many tricks to a s/b and the parts are less expensive.
Good luck with your project....You'll have a blast.
