trying to get around 500-550 hp out of a 350

i have a 350 out of a 88 model chevy pickup. im looking to get around 500 to 600 hp without having to put a turbo or supercharger. i am going to completely rebuild the engine. the one thing i know i am going to use is the edelbrock direct port fuel injection kit. what i need to know it what piston, crank, cam, and heads to use.

Without a power adder such as nitrous, you will need probably 12 to 1 comp, mechanical roller cam, heads along the lines of Dart platnums, in the 220 to 230cc range.And do not expect a daily driver out of it it will idle at about 1500 rpm, and have to turn around 8000 rpm to do it. We have all seen magazine dyno tests that make it look easy,well it aint you are looking to make 1.5 h.p per cube which takes a well set up combo.Good luck it can be done just not as easy as some seem to think.

Oh I forget at 600hp you are really pushing a stock block to the limit.at the very least it will need to be a 4 bolt to live and should have splayed caps installed.Again I am not saying it can't be done but why these numbers? Is it a street car or race car? A street machine with 4oo hp is plenty fast and will not hook without slicks and suspension mods.

IF you want that kind of power N/A you really need to go with more cubes, IMO. To be honest getting 550 horse out of a 454 will be much more friendly on the street than a 7500 RPM 350.

Are you dead set on using a 350? I'm pretty sure its going to cost you quite a bit more to squeeze 5-600 horse out of the small block rather than just going bigblock. And of course, when you have a big block you get to open the hood and say "yep, its a big block."

here's a link from the Knowledge Base to one hundred plus 350 and 383 combo's with build details and up to 500+hp/tq (page 13?) and info source

http://ryanscarpage.50megs.com/combos1.html

500hp 350 motor=$8000+

agree, much better to start with a big block if 500hp is the goal

here's another link just for very general hp build cost for a long block from mild to wild!
http://www.amerspeed.com/scgi-bin/sh...EngineTypeID=3
then click on the "optional equipment" link on the left to price the additional accessories you will need.....water pump/flexplate/fuel injection/etc/etc

600hp on a 350 block is not cheap at all as that is what I run and should be close to that hp number. It idles at 1300rpm and needs 116 octane fuel due to the 14:1 compression i got. I did it for the weight of the motor and spent a chunk on the block (splayed mains and cemented) so it would last. If you want to go small block, go as big cubes as you can which my next motor will be. Good luck on whatever you decide

Save up your nickels and buy a crate motor from a reputable builder that already has all the kinks out of the motor. I think WOrld Products and Bill Mitchell have em and there are many more as well. They build them up to 454 CI small blocks that should get you the power you are wanting and the meek look of a small block for "surprising people." BUt they are expensive.

just like what killerformula said just use a big block you can find all kinds of parts for 454s and you will like it so much more especially if you are on a tight budget

It's relatively easy to build a 500 HP 355. 600 HP is a lot more difficult with poor
street manors.

Check out this 600 HP 383.
