305 Engine Build Questions & Much More - Car Craft Magazine

A lot of tractor pull guys run big engines with 180 cranks. also some of the pro dragsters have tried them as well. But they dont work as well. as the gm crank design.

Its all still in the muffler. Once you got the music it will sound right at speed. Now you got to make your chevy v8 turn 8K rpm. You will also need four valve heads they sound very different. But can also be purchased.

You may want to check out what John Force racing is using there new race engine has a very unquie sound.

Ferrari wishes they had a v8 as compact and light as the sbc. Chevy has many of the best designs going for heads and crank positions. Since they all have major pattens applied you will never see any other maker use the chevy design. Mostly cause chevy knows they got the patten in early and have the best on paper and real word designs. a typical ferrari engine will weight 900 to 1200 lbs turn 8K rpm and only make 240 to 340 hp. Newer engines make more power per cube but do it with better flow and lots of design money. Most chevy alum block motors will shame a ferrari v8 in power to weight and power to reliablity/rpm. Flat plane cranks have some major faults.

SOO much wrong in all of this I am going to leave most of it alone seeing that you have already been corrected by another person thank god.

also so you are aware a flat crank would be a custom job in the 3500-6000 range. depending on who is willing to do it. crower will for a sbc for about 4k. its complete custom. my 3.25 forged crank cost me the price of free. i think i will stay with that.

but it only makes 630 SUPERCHARGED. just do a simple power to cid ratio math.

I really don't know were did you find that: "Most chevy alum block motors will shame a ferrari v8 in power to weight and power to reliablity/rpm"
You are dead on here sir.

(well my engine won't rev past 7.000 rpm, so it won't scream that high)
When all said and done my 337 sbc will be hitting float at 7800rpm

The Ferrari technology is way superior to chevy's, of course it comes at a price way superior than chevy's

My point is this guy said that a chevy engine is better.. no way, it is not, and I'm a chevy man.
<- exactly what would have said... seriously. I think he just doesn't want to listen which is too bad. there is a lot of good on this site. a LOT of crap (seriously there is ) but there is a lot to learn from here.

my favorite sites for car info are here, hybridz.org, and the fsae.com forums.

i needed (a while ago) to do more reading, i got shot down a lot. So i read a lot. didn't say anything to any body on any of these pages much until recently. I think he needs to do the same. Mar 2009 358 posts (including the 9 i just made) vs Oct 2012 and 693 posts case and point...

Ok so the 4.6 mod motor is tuff as nails uh. Mine blew to **** bone stock at 65k miles. Real tuff engine. The engines you see on tv in outlaw cars are forged internal engines. Stock stuff is cheap as can be and not fall apart the first weeks you own the car. Yeah you can push a little boost on them and make some power. But they are not that strong. They make 300 from the factory and at 500 they scatter. Like clock work they pop every time. Sorry go buy one and find out. Also i dont think the laws of physics support your idea of a mod motor that turn 10k all day long. Since the valves to pistons size is not going to allow that much air thru the engine.

Dealer having issue blowing mod motors with graphite powder and letting them idle for ten minutes. Easily the worst decision in green energy future. Crushing good cars and not letting the only industry in the us that actually repurpose reuse and recycle every damn thing get it hands on all the parts to keep another few thousand cars running for years. It was a sad day in the hot rod world all around. Sep for the ford explorers they blew up. That was needed.

to be frank- or steve, or bob... you obviously don't know jack about motors- so it wouldn't surprise me if you didn't know how to take care of your motor pal. annnnnd i'm done following this. kinda pointless. just didn't want the world to be missinformed by you.
