big block vs small block?
#1
If I was looking for (EFI) big block power (500+ rwhp), and you were starting from scratch, would you go with a built big block or a small block with a power adder?

Big block naturally aspirated because I like the K.I.S.S. method I get headaches playing "find the air leak" on a buddies twin turbo 300zx and would you want to run nos all the time to always have that 500 on tap? I bought a built big block from a member here for less then $2,500 and it puts up real near to that 500 you are seeking. plus 500 is a lot of power if you have ever driven something with that? It's insane going from 40 to 120 on just a little over the length of a freeway on ramp in a 560 hp awd '12 Porsche 911 turbo s that I took the opportunity to drive. that feeling of the car accelerating forward so fast that you are pinned in your seat brought nothing but smiles to my face. Good luck in your quest you will enjoy it

Well I had a Vortech supercharged 383w in my '95 GT. With A 2.95" pulley (10 lbs of boost), it made 560rwhp and still passed the emissions test in California. I loved the powe, it idled very well, and had great street manners even in the rain and cold weather.. I've never had a big block and an interested. I'm just not sure what direction to go..

One way to see if you want a big block is to take your car, remove the spare and everyhing in the trunk, get down to a quarter tank of gas, then strap eight 50lb bags of sand to your hood and then do a full throttle quarter mile in the rain and then try to make a 90 degree turn at the end.

Either way you'll be happy but only difference that really marks something is that the bbf is cheaper to built and it's gotta whole bunch of room for growth. Like going 800 hp with stock '80ies 2-bolt block which seems to be dirt cheap at your neck of the woods.

Geez, but you guys there in the US start to sound like European 4 banger guys telling how good Volkswagen 2.0 liter is. Huh?

I have to side with the SBF. In recent years with proliferation of good stroker kits they have proved to be solid performers power adder or not. Also keep in mind the kind of car we drive. If you plan on going in a straight line then the big block to me is a good choice. Cheap and easy power. But the moment you say I want to turn now you made a front rear weight bias issue worse. An aluminum head stroked 351 properly built is a beast of a motor that has a very reasonable weight with alot of power.

Biggest question is what do you want to do with the car? Think of it as building a package and selecting components to achieve a goal. Generally speaking the car you build for drag racing is not going to have the same components as a road racer or even a fun DD.


For the record I am building an Aluminum Head 331 Roller Motor for my 71 that I expect to come in around 400hp NA at the wheels. Budget looks like it will be coming in at about 4-4.5k using very few components from the original 302 that came with my Mustang.

You want to build a Chevy? Ford never made a big block They made a 385 series, an FE series, a MEL series, a Y block, a Windsor. a flathead, a 335 series-but Ford never made a small block or big block V-8

and if you call a Cleveland a "Midblock" in front of me I'll probably slap you

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

If you want to be one those guys. Most every one else doesn't care who coined it. But the 351c was definitely a small block ford by block size measurements...........Haha

I'm just being difficult about the "big block" part Big Grin, but I will lose it if someone calls a Cleveland a big block or a mid block .

And it's not about wanting to be one of those guys-those guys aren't that way by choice, but by genetic predisposition LOL

A mild 429/460 is a great motor and easy to build lots of power and relatively cheap to do so compared to a Cleveland or Windsor engine

Car weight goes up some, but it isn't as much as some people thing- about 200 pounds IIRC and with aluminum heads you can shave a lot of that off too.
