347 vs 393... Pros and Cons

[bluevenom867]

Its hard to beat thous stroker small blocks,especially the big ones.

If they got the cubes,they will run just like a big block only in a smaller,lighter,higher winding package

While your 466 is runing out of steam at 6500rpm,we can pull to 8500rpm and still make power,thats why small motors can beat bigger ones-RPM.And then of course power adders just level the field even more.

Anyone who has drive an bigblock will know how much fun they are. My uncle had a '76 Ford F-100 with a Olsmobile 455 in it. A true redneck-engineered junkyard setup, so it didn't have any "performance" mods done to it. It had a real highway gear in it, sat at 1200rpm at 65mph with a non-overdrive transmission, about 50mph in first gear, but if broke traction with McCleary tires on the back at 1/3 throttle from a rolling start, it would catch, put it back down 1/2, break traction again, catch, put it down 2/3rds and the secondaries would open and the tires were smoking agian and didn't catch until about the end of the gear, bark the hell out of second. No top end though, but still enough to have fun, only ran 16's in the 1/4 one wheel peeling down the track, ugly as hell, complet POS, but lots of fun. Oh what fun, the memories... Now, that motor in a light car, couldn't imagine it.

Im not trying to argue here, but you can build a big block to run at 8000 rpms, many on the 429/460 forum with pulling trucks and mudders do it all the time. Mine is just a semi-wild hydraulic build, made for the street, i don't see the use of winding to 8500 rpms on the street.

Think powerglide


If your looking for all out power I would do the bb, if your looking for a very well manered street maching imho a sb is better. Speaking of BB fun, anyone ever had the chance to drive a 427/428 a/c cobra? Thos are fun as hell, I remember the first time I bottomed the gas on one of those I had perma grin for like... well I think I still have it, and that was like 8 years ago

Ahh yes,but you got to put alot more dough into it than a small block to turn 8000rpm's.

Besides,big blocks arent meant to turn high rpm....there meant to be BIG

Like a Jon Kaase built 900 cubic inch BBF....1600hp n/a good for ya?

and just imagine for a second this motor running higher rpms

High rpm motors cost serious amounts of money, the cheapest way to make horsepower will (almost) always involve bigger cubes.

Who ever said "Theres no replacement for displacement" must have been a "red neck".

Just think tractor pulls

 

[ExplodingGopher]

I'll take bigger displacement and boost....thank you...

All right,and lets throw some nitro in there while your at it

and don't forget one of those tornado air swirler thingies

Why would you put a forged crank in a stock 302 block?


Some guys have a hood already...so thats one less thing for a 351w based motor. Unless u figure out how to drop the 351, you will need a taller hood.

They put a 351 under the stock hood of the sn-95 351 saleen.

 

[90mustangGT]

Turbocharged Big Block Stroker.... the words togeather sound wicked, now imagine the sound of this engine at full boost. Muhahaha!!!

No, there is not replacment for displacment, but there are other ways to make power. However, run what you brung, and hope it's enough. If someone has everything you have, but your lacking cubes, everything else equal, your going to be lacking the win.

Personally out of all my car adventures of riding and driving cars, big blocks are definatly the most fun to drive and ride in. My uncle has a 1971 Trans Am with a 'mildly' built 455 and it kicks you in the ass harder than just about anything else. We took it out on this back country road and nailed it, it just went and went and went it seemed like all the way to 120. I don't know, big blocks and small blocks just have a different feeling to them to me. It just feels like you have an infinit amount of torque behind you in a big block.

 

[ExplodingGopher]

Thats why i enjoy my car a lot more now than i used to.

Have you ever riding in a car with a big stroker small block?

If its got the cubes it will pretty much run just like a BB.

Thats true. So was it the intake that was shorter? Or did they use drop mount? Thats something good to investigate. I believe some guys have got under the hood but im not sure. The average person and easiest would be just to get a hood. If you drop the motor, with drop mounts or a k-member, then that disturbs the tranny and the pinion angle.
