Hey guys i've decided I want to build my own 6.0 block from the ground up and am relatively new to lsx engines. I could use some help with what route to take as far crank/rods/pistons/cr etc etc. I want to have 500-550whp NA and i'm still somewhat undecisive if I want to turbo it (I work for Cummins so Holset turbo would be cool) or spray it. I know i would have to build accordingly for boost or spray. I would like to buy the 6.0 block for $750 and go from there. What crank/rod/piston setup would be the best bang for the buck? I've heard of people doing stock crank and callies rods and making some good power safely. If i stroked it to a 402 or 408 would there be any additional machine work needed? What heads would be the best bang for the buck? If you guys could point me in the right direction to help me with some ideas i would appreciate it, thanks

 

I got an iron block lq4, bored .030 over
Eagle 4" crank, eagle h beams, je coated pistons
PRC aftermarket ls3 heads
Pat g specd cam

Hoping to hit about 530+

Getting 500rwhp with stock cubes and a still streetable cam can be tough. Its certainly not cheap.

 

Thats why i plan on stroking it to a 402, and I don't plan on it being cheap I just want to spend my money on whats effective for the build. How much was your rotating assembly? Did you go with a steel top ring? Did you have to machine the block any for a bigger stroke or will it go right in?

 

Just saw that you're from Indy. I live in Columbus, IN were not too far from eachother

 

feel free to come check this shortblock build out if you want.

I paid less than $1000 for my 408 shortblock cause I got it as part of a killer package deal, all brand new parts just unassembled. Block was already bored, cam bearings were installed, block was sonic checked prior to boring as well.

rotating assemblies go for roughly $1800

 

What part of Indy are you located at?

 

SW side right off 465 and kentucky Ave, near the camby /west newton area

 

well i just purchased my aluminum block machined for $900. Ive seen the iron go for $300 pretty cheap. I plan on doing the same build i want as close to 600whp as possible.

 

Youre going to need a lot.
408 with the best heads money can buy,, a donkey dick cam and every imagineable bolton

 

I'm kinda thinking a turbo ls1 build would be sick. Thats why i need help making a decisive decision. I could have the block gone over buy a forged rotating assembly, increase ring gap and boost it to the moon. I want my car to be jack of all trades. Low 11s high trap at the strip, good on the street, and decent at a roadcourse

 

Lol start with a lighter car i was torn between a wide range of cars and went the 240 route obviously. They can be had dirt cheap, plenty of upgrades and CHEAP, and what part of 2850lbs amd 640 HP doesnt sound like a ton of fun?
