heres a 307 http://youtube.com/watch?v=DIa747QG6AI

a guy i used to work with used to race comp eliminator in nhra in california his 351 ford used to tun 8500+ with his lenco mustang youg uys just havent courage to go for the gusto if you scatter it you scatter go back look see why it did it and fix the problem :P

When you can make the same power at 7500 RPM, then why bother with 8500???? I guess I can do without the big RPM bragging rights, and save on the parts. Never found gernading engines to be that much fun.... Takes a mighty big pocketbook to run with the philosophy of blow it and start over!!!! I guess when you break enough parts, the mindset changes.... Hard to win when the engine breaks, too.......

don't tell me that a t/f eng makes the same power at 7500. what about pro stock, big blocks turning 9k. what about stock elimn 10,11 k. they don't blow every run. you know all the reasons.

i agree whole heartedly

Well, if you have that kind of money, then run one!!! I sure as heck don't!!! The 7500 RPM engine can make more power....Especially if it's a 408 stroker vs. a 351 stock bore. Small cubes require a lot of rpm and a big budget to make horsepower... Big inch engines built with more economical parts will make big torque.. Torque is much cheaper to build then horsepower. I guess to the millionaires in the crowd, high RPM small inch engines are no big deal. The reason the pro cars don't blow every run is that they can afford the good parts!!!!

And, as I said before, you can't compare Top Fuel, Pro Stock and Stock Eliminator engines and the components they use with a 283 running stock parts and an aftermarket piston.....

So, wanna talk real world Scooter!!!! which makes more economical sense on building a competitive engine THAT WILL LIVE round after round.... A 302 winding to 8500 RPM every pass, with the trick soft lock clutch, all the trick engine goodies like a billet crank, billet rods, ultra lite pistons, roller cam, battleship springs, etc, or a 514 stroker shifting at 6200 with a cast crank, I-beam rods, and a small cam with light springs???? Now remember, I said an engine THAT WILL LIVE round after round...... Our big engine got 100 passes on it last summer, replaced the rings and bearings, touched up the valves and it will do at least 100 more this summer..... How many passes do you have on yours without parts breakage????????

making a huge rpm engine can be done but you need really big $ to get there. sure its really cool to see a high tech motor hit high rpms on the 1/4 but its much cooler too see a reliable oldschool motor make the same 1/4 mile times with gobs of torque and reasonble r's on a tighter budget. i love watching the low buck guys clean up on the guys with the big $ and a big block will get my attention way faster than some high rpm small block. if i wanted to see an expensive high rpm motor, that i can make more power than (with less money) i would go look at one of those fancy v-tech 4 bangers the honda guys run.

looks like there's more then one of my kind..... http://cgi.ebay.com/ebaymotors/CHEVR...QQcmdZViewItem

\You mean impractical people who haven't yet blown up enough engines cuz they like the sound of high RPM?????? Big torque engines moves cars to the desired ET at a much more cost effective rate then high RPM.....

hey you use what works

The new standard is about 6500 to 9000 rpm on most performance /high hp builds.The new vette is stock at 7100 rpm now ,with a 100,000 mile warranty,the highest factory rpm yet to date.I have read that the pulling trucks are regularly going into the 8000 rpm range and occasionally 9000 on the big block fords with a cast crank { a 1200 dollar scat or equivelant},stock block and heads and some good I or H beams.I have even heard some of the guys hitting 10000 on the big blocks when a clutch or driveshaft goes..........Theres little need to go that high on 95 percent of the builds because ,like Dave said torque moves you and theres little need for the high dollar parts when you can accomplish the same thing at a lower rpm and use that engine for along time.
High rpm motors are usually tore down on a regular basis and blowing them up is part of the norm.A big block is going to run strong and long at a lower rpm and do the same thing better and cheaper than high rpm stuff.The high rpm motors are also usually built for a specific purpose and because of rule restrictions ,such as formula 1 and mostly used in road racing .Big cubes and lower rpms is king on the street and the track going in a straight line and much cheaper to do.The big thing for me is safety,a 10000 rpm motor is going to exsplode like a atom bomb and destroy everything,a big block blowing up at 5 or 6 grand is going to be alot less devastating and less likely to happen.
