If you want to build a motor with no car you do it. Im doing the same thing. The motors the most fun to build. Obviously you want as much power as is streetably possible so what it goes in is a moot point. Obviously youll be buying a car that will accept your motor. I cant imagine you buy a car and then as your dropping the motor in you say "ah darn it has too much HP it wont fit". Picking a time to shoot for is a bad idea because if you cant afford to go that fast then you wont. If you can afford to go faster of course you will. So you do what feels right and make all the power your wallet can handle. Guys like us are a breed of our own. To put it simply we just want to go as fast as possible.

Dont let these grumps discourage you, Stick with it kid!

not sure if that's directed towards me about the motor, if so, what info are you looking for?

as far as discouragement, this may not be the ideal way to do things but the kid is interested in some old American iron and not wanting to learn how to put a fart can and giant wing on his four door Honda, so in my mind he deserves some help.
i myself have built a motor without having a car to put it in. why? because i had a bunch of cast off race parts i didn't need for anything else and a little spare time in the shop. eventually it went into a car and runs great. ideal? no. but if you plan that it will likely be going into a car that is 3500-4000 lbs (a whole lot of gm cars fit in that category) he'll be fine.

I think its more like he thinks he can make 500hp on his budget. Im sure hed be building a 1000hp motor if he thought his budget could handle it. Forget about the number in question. Hes just looking for a flight plan to follow to make as much HP as possible on 125 bucks a week. I bassically had the same type post not too long ago. You guys helped me. Yes it was like pulling teeth for info from time to time but i am a lot better off now. Im very grsteful for the help i get on here and will continue with my questions without a doubt.

If it helps lets pretend he has just entered a motor dyno competition. he has 1 year to build the most streetable power he can. aaaand GO!

First thing you should do is go check out some the Horsepower books, on Amazon, Ebay and your library.

anyway there is a bunch of these books, just note camshaft, head and intake information may be dated. Heads are where you make your HP, and good heads cost lots of money. The "cheap rout" would be to go with vortec heads, you can make about 450hp with them. Spray with a 100 shot of nitrous for 550hp.

Bang for the buck parts, scat forged crank and rods, probe forged pistons. Just remember you don't need to use any of the parts you have! You can probably sell them off, buy a junk yard big block and be way ahead of the game in terms of power and money. Last summer my local pick N pull had a complete 496 chevy for $950 with a 90 day guarantee.

Buy a $300 used 5.3L, get a $150 cam regrind, and a $75 set of valve springs, a used $100 intake, and port and mill the heads and swap your gaskets ($125 gasket kit). Run it with a retuned factory ecm or megasquirt ($400).

You can get damn close to 500hp and for less than a third of what it will cost to build that sbc.

Or just slap a turbo on a stock 5.3L and you're done.

Don't forget though- it may or may not easily fit into whatever car you decide on getting.

You're putting the cart miles before the horse on this one, but no one seems to care as its not their money. Properly done you can make almost any car fast- BUT a sbc only fits in a very few of them.

RE: AP72 s post?
Ive considered doing this type of engine myself,what I would like is specifics?

regrind the cam to what specs? mill how much off the heads?
what exact intake? port what part of the heads and what would they flow after porting? Where do you get the ECM reprogrammed exactly? Which 5.3 is the best to start with?

Not any 5.3s where I live for $300.oo,closer to a "G" note.

If I turbo charged a 5.3,what size turbos? N.A> 5.3 I see as an easy 380 plus HP,just not sure where the rest comes from

In my experience you can put a SBC in almost anything.

Mike Jones can regrind your cam, to about 215/220 I believe which is actually adequate for a 5.3L (though pretty small for an sbc), mill at least .030" off the heads, more than that and you may have to finagle the LS1 or LS6 intake a little to fit. The heads depend a LOT on each person but 270's on the intake is not too much to expect with stock valves. You can do th ECM yourself if you have the correct tuner (I prefer MS though), and the best one is the 5.3L HO with the aluminum block and flat top pistons.

Consider you're talking to a highschool kid who doesn't even have his first car yet...

Also consider that getting a 4 banger import car into the 10's is NOT that uncommon any more, and finding even a clean '80s G body for an SBC race car is not as cheap or easy as it once was.

Just a basic sand off casting marks. Since they are so good from the factory most ppl dont bother porting at all.

Turbos will surely do the job. But if your building a custom turbo kit you will need to design a proper system for that power level. The t3/t4 with S 60 trim i have would support 600hp but it is matched up for my 1.6 honda with the over sized turbo you can make more power wothout having to worry about bad air. For msost v8 builds two t3/t4 garrets with the open exhaust and external waste gates work the best. Will support 1200 hp by air flow numbers but is well within the range of 600 hp. Dont worry about lag thats a myth that only effects poory designed factory engines with 7:1 compression and under sized cold side turbos. With 9:1 compression and about 10 pounds of boost it will be spinning the tires before the boost kicks in. Then will really start to fry them. But thats another thread in its self.

I am willing to buy any 300 dollar LS motors. An entire truck load of them would be even better.

You can buy good cams in oem and aftermarket parts stores.

Factory ECM is not cheap to retune or purchase unless you cna get an entire swap kit because the sensors and wiring harness is a lot of money and time to make up from scratch. Buying the entire swap is the only way to go efi with LS motor.

I actually would love to learn a little more about the LS swaps with factory ecu and LS 6.0 not the little baby motor. The 6.0 will turn 7k without scrapping its self sounds like a crap load of potential to me. But dont want to drag this thread down with it. Since there is so much too the swaps. Especially if all you have is a long block. With a long block you still only have 25% of the stuff you need to install and drive.

I still would be happier with a 010 block and dart heads. Its not like he is sarting out with nothing here. Its at least a good start to a powerful build up.

Sorry about the book...
5.3L heads are not any different than any other heads, the same principals apply. You can screw them up, but you can also make significant improvements as long as you're not an idiot. Luckily I haven't been stuck on sbc's my whole life (as a lot of people have been) and I have seen that when it all comes down to it, the principles are the same for any 4 cycle IC engine.

Before you spend 1 dime on this you need to make yourself buddies with someone that has all the measuring tools and has some experience rebuilding engines. You already told us that you got taken when you bought this motor. You need to measure the block and piston to see if they are still usable with each other. Just because you maybe able to see crosshatching in the bores half way down doesn't mean that there isnt so much taper in the bores that the block is unusable, maybe it is. This isn't something that can be deternimed by pictures. The skirts of the pistons may fit well but the ring grooves could be worn out.
If these parts are in usable shape this could be a great first engine to rebuild but just getting yourself the tools a place to do it maybe beyond your means. If with the help of buddies or school auto shop project can learn to inspect and rebuild this correctly it can be a valueable learning step. A correctly rebuild sbc usually can be sold quickly if you end up with a car that can not use it. For a first engine you should probably stick with a basic stock rebuild with a mild hyd cam and horse trade your victor intake for a nice dual plane plus some cash.
