Stock crank can take all the power that you can throw at it with a Whipple. Forged pistons and rods are what is needed. That being said, you likely need a new crank anyway and certainly a new block. So you really can’t go wrong with buying a forged short block. Thompson, Texas Speed, AMS, CNC Motorsports…there are many good options.
I just finished my build. I took out my stock engine with my Kenne Bell because the high flow cats let loose and plugged in my x pipe. So I went the route of ordering a forged rotating assembly from CNC motorsports, had my stock block honed, and put it together myself. Lowered the compression to 9:1. I went with a BTR stage 3 “torque” cam. I also went with Frankenstein M311 heads but that was overkill and I don’t think gave me much of anything as opposed to ported LS3’s. I then put a big fuel pump in and went with E85 as well. Pretty happy with it. 710 rwhp at only 10 psi. Lots of good options out there. Forged pistons and rods, and a cam are a must. Everything else can be added, but you’ll get the most from those 2 things. |

I reached out to Thompson (spoke to Shane). First issue is they are 5-6 months out on new LS3 block inventory. So he suggested an in stock core which would save time and some money. He said the cores are fully tested, scanned and blueprinted and come with the same 12-month warranty as new.
I attached the quote. This includes forged pistons, rods and the crank. Also added in the Moroso high pressure oil pump and a cam. $8,700 with shipping. New block price would be $10,200 and the wait time. What do you guys think of the package Thompson put together and going with a core block instead of new? |

But it. You can’t go wrong with that. You start trying to piece it together yourself…you’ll end up with more $. Ask me how I know!

I'm gonna sit on it over the weekend but I think I'm going to go for it. Thompson guy said no problem running my stock heads although he suggested since I have 70k miles on them to replace the springs and maybe while I'm in there upgrade the rockers? I am not doing any other mods to them now. He also said I will need to get new pushrods for the new cam he specified. How in the world do I figure out what length I need? |

Thanks! Yeah not going through a shop. I'll figure out how to measure them.

Yeah it's not to hard. Just get a pushrod length checker adjust it to zero lash without the plunger depressed and measure with a large dial caliper and then add how much preload you want to it. That's how I did mine if I remember correctly. I'm sure others have their own methods.

Down the rabbit hole the OP goes.

On the Thompson website he shows an easy way on how to measure for the correct pushrod. There are many other ways to measure besides what he shows...
