Current Setup

Been away from this for a while with military deployment stuff and training that was dropped on my last minute last spring and summer and now I am all settled in at my new assignment in Connecticut so I can get back to business.

I did get my bottom end built and stroked to a 5.3L on a Boss Block by MMR while I was away. Have a kenne bell set up on it now but just not that happy with it

Hopefully I get this build back on track.

Current Setup
Rear Axle: Ford 8.8 31 spline Detroit tru-trac with 3.73 gears
Ford racing aluminum driveshaft
Transmission: Built 4r70w (upto 750 rwhp) with a 2800 PTC converter
Engine: MMR 5.3L Stroker 9:1 with ported PI heads & MPH cams
FI: Kenne Bell 2.6L with Behemoth inlet
Fuel: Returnless - GT tank, Cobra hat with dual 340Lph pumps, 40 amp BAP, 80# Injectors, Fore Rails

Future Setup
Rear Axle: stay the same or suggestions
driveshaft: stay the same or suggestions
Transmission: saty the same or suggestions
Engine: Swap to TFS 195cc Race Heads with MHS Turbo Stage 3 Cams
FI: Twin 66/67mm either turbohorsepower or hellion suggestions
Intake: Edelbrock or Logan if still available suggestions
Fuel: Return with Cobra tank, Fore hat, dual DCSS 465Lph pumps, -12 or -10 feed line, use current feed line as return

Plan for now is to tear down a little bit at a time - sell the Kenne bell and the ported heads and swap the heads and intake and go temporarily NA. Upgrade the fuel system and then get the turbo kit.

Started the tear down today but didn't get far

Probably shooting for 750-850 whp on 18psi pump gas - Spoke to Jim from turbohorsepower and he say his kits would hit 750 whp at 15 psi and 15* with my engine as it sits now wth twin 57mm.

Yeah its a berry motorsports intake to match the mph inlet

Got a little bit more of the tear down done this afternoon and evening

Had a scare with this allen head manifold bolt - rounded it a bit but ultimately got it loose - I hate allen head bolts especially aluminum ones

Supercharger items that are for sale along with the Kenne Bell:

Gonna make a for sale ad once I get the blower off but if anyone is interested in upgrading to a 2.6L Behemoth this would be a good set up let me know - shovel, creeper and radiator/fan not included :whackylol:

Quoted for truth! I'm actually considering having E85 delivered at some point.

How much power did you make with the 2.6?

Looking forward to seeing this build materialize.

Made 594 rwhp with 17lbs at 17* of timing through a stalled auto but it was on a fresh motor build so everything was still tight. Kenne bell markets there numbers at 23* of timing which is crazy high that's probably why anyone rarely achieves them

Still waiting for my engine hoist to get delivered - fedex messed up the box and had to send it back to harbor freight so they are sending me another one but I gotta wait another 3-5 days before I get the hoist and can remove the Kenne Bell - unbelieveable

Holy ****.

As for fuel system, I like a sumped tank with an external pump (A1000 or larger), -10AN supply, -8AN return. Just my thoughts.

Engine hoist is the way to go for installing/removing blowers. I did it manually the first few times, and the engine hoist made life so much easier.

Eager to see the stupid power this thing will make.
