Many of you have seen my current build come to fruition over on CF through the many DIY guides that I did. We’ll, due to an issue with the T-trim blower at the time, it was time to upgrade to a YSI. So, as I was tapping the pan, I decided to be safe I would remove it. Many of you know this is a major feat on thr C7. Once I got the pan off, I pretty much decided I wasn’t far off from pulling the motor, so I did just that.

Heres what my current build was:

- LT1 (wet sump)
- Vengeance Racing dropin pistons (11.7:1)
- Stock crank
- Stock connecting rods
- Vengeance Racing stage 2 DoD delete cam
- TSP ported heads and 5 angle valve job
- Comp Cams 850 lifters
- LS7 lifter trays
- Vengeance Racing hardened 3/8” 7.800 pushrods
- Comp Cams Trunnion upgrade kit
- Vengeance Racing dual .660 titanium valve springs with titanium retainers
- A&A V3 Ti supercharger, 3.47” upper pulley, 8.25” lower (approx 15psi at 6500)
- Dual Alky Control meth injection (30 GPH / hour)
- Full LT4 fuel system (HPFP, injectors, rails)
- ARH 1 7/8” long tube headers with catless X pipe
- WeaponX ported intake manifold
- WeaponX ported throttle body

This configuration put down 850rwhp and 730rwtq on a mustang dyno with a bellmouth on the blower, and ran a 9.92 at 140mph in the 1320 (M7 manual trans)

Now, its time to tap it for more. So, with the motor out, I am upgrading to the following:

- Vengeance Racing stage 3 cam
- Fresh set of Comp Cams 850 lifters
- whole new balanced rotating assembly from TSP which includes stock crank (stock stroke)
- Wiseco 10.5:1 pistons
- Callies Ultra I beam connecting rods
- A&A YSI blower with a 3.33 upper, same 8.25 lower
- E85
- all this will be handled by a fresh new tune to account for all the changes.

So I am sure this thread is useless without pics right? Heres a few of the belly of the beast..

Ant, will you be running pump gas and did you have to modify the drivetrain any? It's going to be a "Fire Breathing C7 Masterpiece Beast"!

I will be running 93 pump with dual meth still. I’ll be able to run about 45% blend of E85 as well. For drivetrain, I am running a Mantic Twin clutch which may need to move to a Mantic Triple. I am also in the process of fortifying the rear end with a custom 4-pinion spider setup, 300m stub shafts, and DSS axles. Just waiting on the rear diff machine shop work to get done. :)

Ant, you are building the ultimate C7 BEAST! Hope you allotted lots of $$$ for rear tires. :cool:

What a monster! I’m guessing after that sub 10-second run that was it for the 1/4 mile, unless of course you have a roll cage and such. That thing would make a super bike blush!

Thats NOT it for the 1/4, and I don’t have a roll cage. :D

I mainly do track rental events and they are lax about requirements. :)

Before pulling the motor when I decided I was only pulling the oil pan, I had to take a lot apart including dropping the cradle:

Current situation - I have fully reassembled the cradle and suspension, put wheels back on, and put the car on wheel dollies. I hand washed the car in the garage since it was filthy and put the car cover on it and moved the car to the side of the garage to make room for the engine construction area (hard hats needed at all times.. LOL)

Ant, very nice garage/work area set up! Clever use of magnets on the cabinet doors. Did you have that recessed ceiling where your bike is hanging specially put in? Very cool :cool:

Thanks! Actually that recess was there already since that is where the AC Air Handler is at. :)

I suppose this thread is due an update actually..

Current status - Block is back from the machine shop. Cylinders honed and bore came out to 4.070” this go around. New rotating assembly has arrived and is ready to go in along with all gaskets, seals, and bearings.

I’m in the process of cleaning the heads at this point. As in, pulling the valves to clean them up on the wire wheel, and cleaning the intake and exhaust runners up. Here’s some before and after photos
