5.3 Rebuild kits people on here have used? and Build sugestions

[jbauto]

Was going to go with a LY6 and swap it in but i dont realy have the time as im deploying after xmas. I got a 5.3 block here im gonna do a quick over haul on new pistons rings bearings ect.

I want to bore it .20 over and im gonna do a quick light port job on the heads and get the seats done at my buddies shop.

What kits do you guys recommend ?

Im just looking at doing a small cam. long tube headers and exhaust and HP Tunner ecu. Also will be using a Maddog trans for this build.

Im just looking for a better pulling motor good on gas.

Thanks guys

You might be better off going .100 over and doing a clean up bore for an ls1 to make it a 5.7L. .100 over might sound crazy to you but there are a lot more piston choices for that bore. I forgot what the rod length is.

rod length would be normal 6.125 if you want forged stuff or just stick in stock ls1 pistons and rods.

No this truck is a daily driver and hauler i dont want to build this motor so stock rods and OEM replacement parts and i want to be able to run pump gas 87 octane.

Is there a piston compression calculator somewhere?

[GraniteBlueNNBS]

Your gonna have to punch it .100 over use stock rods and get some stock LS1 pistons...

What will this yeaild compression ratio wise with the 862 heads?
