Default some qeustions about building a ls1

Ive been laying low on this forum and others for a while. And tossing up the idea of cars first i was gonna get a 5.0 then a 03 cobra now a F-body. Im wondering how much money i can build a ls1 for to get over 500whp on the bottle. Id like to see upwords of 500whp to low 600whp. With say a 175 shot or more juice. Whats the cheapest way I can go to get atleast 560whp or more.

Thanks alot guys means alot to me,
Nate


ps if i posted this in the wrong spot id apreciate it if a mod would move it

probably a big cam, full boltons and your spray... you would have to get to 385whp N/A, which shouldnt be a big problem cam only. I dont know how big you could go without needing to flycut the pistons though. Shouldnt be too many things involved, if your using that much spray.

you don't need a cam to make good power spraying

You don't NEED a converter to make power spraying either. You may need one to do it twice though! Seriously, That list seems like it would do it, but I'd cam it personally. One thing to think about man. Although it's gotten cheaper than it was five years ago, the LSx isn't the cheapest powerplant to work on. If money's an issue - that 5.0 you named would be the cheapest to purchase and to work on. Wow I'm gonna get flamed for that one!

up untill you split the block in half. before you do that, they are the best bang for the buck

they say the older 5.0 blocks hold up fairly well. you also have to remember your driving a 20 year old car and daily driving something that old would scare me......... but as with the rest of us, i'm partial to the ls1's but i hang out with all 5.0 guys

for the money, 5.0 the cheapest. 500 rwhp is not hard. you will be getting close to the limits of the stock block. 500 rwhp is a mid 10 sec car in a set up stang.

Ive looked in to salvage title cars because its the cheepest way to go. So most of you said the 5.0 os the chepest way to go so i think thats what its gonna come down to. Ive heard the limit on the block can only take 500hp though so I want a car i can put a max of 3k miles a year on it so I can get cheaper insurance. By no means is this just gonna be a car that will just sit I want it to be driver friendly also.

Thanks for all the advice,
Nate

500rwhp cant be cheaper in a 5.0...Ive had 4 of them...remember you are only starting out at 225 at the crank barely. Junkyard LS1 has to be cheaper to 500rwhp...100hp+ lead on the 5.0...and much more durable.

your comments are true. however, you left out several important parts.
cost.. as in cost of parts, cost of car,..cost of driveline, cost of suspenion....

not to mention. ease of working on it, parts availiblity,ect

like you, i have had 5 5.0's. i don't know where you buy your ls1 stuff but, i can build 2 5.0's for the cost of what my camaro does...

First of all...he was only talking horsepower not chassis, suspension etc. Completely different subject. Race car chassis..LS1 is way cheaper...drag car chassis...5.0L is cheaper.

Engine parts such as heads are better priced. Look at all the ported ALUMINUM LS1 heads for $1k that will outflow any 5.0L head you can buy. I bet a 300cfm aluminum 5.0L head costs $3000. What about the 5.0L tranny..you have to replace that for 550rwhp...

If you want a 5.0L to go fast...then drop in a Helion turbo kit with a cam/loudmouth exhaust. 5.0Ls are old news..flowmaster exhausts are as bad as rice rocket pipes. Get on with the future.

Speed cost money...save up a bundle and then see how fast you can go. The last Ford I owned was a new 1993 Cobra..ran low 14s at 96mph stock..got spanked by a new stock 1993 LT1 that was over $5k cheaper to buy.. sold it before I built it and been with GM ever since. No substitute for cubes until Ford started using the blowers to keep up. why would anyone own a ford without a blower?

5.0, Andersons high rev cam, Anderson ported TFS head (309+cfm), and a good full bolt-on package on the right suspension will get you 10's

^ not very likely on a stock bottom end 302. LS1 is definately the cheaper way to go. The 5.0 block is good for about 450rwhp, anymore and you're taking a risk.
