I had a customer from CA call who had a ProCharger on his truck and it had a catastrophic engine failure. He wanted to build a stroker longblock, so I decided to shoot photos along the build.

This build consisted of:

jesus... mod motors are so physically large. my 416 ls looks like a tinker toy next to that thing!

Livernois Motorsports

Yes, they are quite large. People that don;t know think they are a HEMI, especially the 4V's.

Rick...How much can the stock 6.2 take before it grenades? If I go to a turbo or Supercharger do I have to swap pistons, rods, crank etc.?

Livernois Motorsports

Thanks!

Unlike some of the other platforms we work on where the customers want to push them hard on stock parts, it seems a lot of our Raptor customers do bolt-on's (CAI, headers, exhaust, tune) and leave it at that or they go all out and do a power adder and engine at the same time.

Honestly, I'm not sure what kind of power the stock parts will take. The OEM crank is nice, but the rods and pistons are powdered metal.

Reading online, I see a lot of engine failures with power adder Raptors.

Thanks Rick. I think there are no shortcuts in using Power Adders, regardless of what your working on. I can handle the $6-7K but changing pistons rods, etc gets into some serious money. Pay to play.

Livernois Motorsports

No problem!

We have some late model GM cars making 700 RWHP reliably on the stock bottom end and no issues. Obviously it's different with a big, heavy truck.

Same engine combo... different build

Rick...Your killing me....This is like crack! I'm hooked. I talked with the CFO last night (wife) about doing a twin turbo build. She just shook her head and said "how much trouble are your going to get into with that?" She said sell the IH Scout 800 so we have more room and it's a green light.

Now the question is turbo or supercharge....
