When the time is right I would like to build a nice motor. Now I have a Camed LS6 and its fun, but would like more.
Iv been thinking of going with something like a 418 or 427. I would stay N/A more than likely.
Whats some good and bad things about them.
Whats a stock style head seems to respond the best with them. (LS6,LS3/L92s ECT)
I want torque and good top end power, something around 525-550 to the wheels. Still want to stay streetable like what I have now. Is this possible with out spending tons on heads?
Would it be cheaper to buy a LS3 and go from there, or like an assembled motor from Texas Speed or somebody like that?

LOL we need alot of info here first whats your over all amount your will to spend.
no motor has a pro and cons till you speced out the motor and have it built cause every thing you add to it change the effect.
my pro might be different from yours what are you looking for Are you looking for a all stock head or a ported stock head ?
I there has to be 20 different way to just build a 427 on for 4 different types of blocks and crank strokes

416/418 is much cheaper due to all shelf parts mainsly but 427/429 will make slightly more power NA. We do lot's of both and the 416 can be done very quickly whereas we have to wait for pistons etc for the 427s that we do at least.

Im not an engine expert. I take my car to people and tell um what I want. I havent even really looked much at what this would cost. What I want is 525-550 to the tire on pump gas, Iv got a 6 speed, 12 bolt w 4:56s, Full Suspension. Wanting to run mid 10s in full weight pretty much(if possible). Just a healthy N/A Street car that I can drive to and from car shows. I know with a little more work to my set up now I could see 10s, but sooner or later this thing is ganna come apart..
Cheaper the better I, Could I get waht Im asking out of a 416/418? What would something like that run just ball part for a long block?

Well, I'd always talk with the vendors on the site, Texas Speed, Virginia Speed, and some others to get some answers to your engine questions and to see if they can come close to meeting your budget if you have one. If you use LS3 heads, they make lots of power for budget guys.

im kinda have the same mindset. but in reality, a 347 with a procharged setup wouldn't be much more if none at all and the power difference would be a big diff. honestly imho, if i could row my 6 speed an trap 130mph and the only thing i have to do is oil changes an worry about nothing, that is the way to go and that's why n/a is so appealing to me. also, another thing that is so appealing about n/a is if you wanted to do another car preferably a classic cough "70's trans am" you have an bad *** engine an trans to go in.
then you can use a cary's carb setup on there and be close to 700hp n/a...sorry guys i started dreaming a bit![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
erik, so how much for a 427/ls3 with a fast 102 setup topped with the new afr 245's![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
on a side note, i forgot the exact pricing but what's the price diff roughly between a 427 ls3 and a ls7 440? im thinking $1500?
