ET'S with ported J/or other iron heads SB
I've already said it and I just said it right there you've got to start with some expensive *** r block it's not just the run-of-the-mill 340.. I understand everything you're saying but the people riddle off on the internet like they can do it off the back of their hand and it's just not that simple.. my buddy did X time with a 340 and stock heads.. and when I call bull crap I'm being rude to some internet Guru... There's a link to that ad about that guy's duster for sale that's record-holding stock Eliminator and it shows the entire build and it's nothing to frown at.. I get it it starts with a $3, 500 block and works its way up from there...
you can tell me a million times what it is but people like to disguise it like it's something else and when I call it I supposedly get the lesson...
First off, you don't NEED a block. Blocks weren't 3500 bucks either, until Chrysler crapped on everyone. I don't even think a Ritter is that much.
So let's do some easy math and see how hard it is to go 9's. Let's say 9's at 3100 pounds and let's say 9.80ish just for rough numbers.
To run a 9.80 in a 3100 pound car takes about 620 HONEST HP. That's all. I have zero doubt there is no less that a dozen and a half engine builders on here that can do that low number falling off a log. The number isn't hard to hit.
So, you can take a 340-360 base engine, get a decent piston, the correct cam and a set of very well ported iron heads and you can do damn close to 600 on pump gas. You'll be shifting at 7500 or so, but who cares? If you use a 4 inch crank you can drop the RPM down to 6000 or so.
Edelbrock heads make it even easier, but even on pump gas 280 CFM and a well sorted combo will do 600 hp or damn close. I did 565 on Edelbrock heads with a hydraulic roller and 10.5:1 compression back in 2000. But I did the heads and I did the intake manifold and I spec'd the headers and ignition.
If you're not sure about that, ask lead69. He was privy to that build.
That engine above would have made 50 HP more with a bigger cam. It was grossly under cammed. A solid roller would have added another 35-40 at a minimum to that. All on pump gas.
And you have to have the chassis to support that. I see lots of 500 hp engines running 12's because they ain't 500 hp. And I see a lot of 500 hp engines running 12's because the chassis and the chassis tune up is junk.
