Facepalm. If you read the thread you would know my car is terminator swapped. That is what I was saying. Both cars run low 6s.

VMP blowers work damn well on mod motors. Why'd you stick with the 4R70? See a lot of them swapped out on higher HP builds. Nice car.

all of the ford transmissions besides the c6 have to be changed out. the 2-3 shift is synchronized on all fords. flare kills them. both 2 and 3 engaged at the same time partially. they can be built to handle 1k rwhp, but it's always a time bomb. may last a season, may last one pass. even of they are built for maximum power, they fail at lower power levels. i've popped countless built c4 case fills. and that's with just a decent 302 with 125 shot.

the 4r in my turbo has only lived because of the valve body. lift shifting, and a 30 second lock up timer. no O/D, and no lock up with decent power. they also have a hard wired 127 mph shift onto o/d without a guru modding it, or fooling the speed sensor. some day i will build the glide. chevy transmissions are the answer.

MACH 1 motors (manual) do have factory forged cranks. Hypereutectic pistons and rods and aluminum block. Same heads and cams as 03/04 Cobras.
Saves a bunch of weight but does not do anything for strength. MACH1s were not manufactured for boost since they had the SVT Cobra for that. The MACHs were really just a nostalgic throwback to a quick light weight NA car.

Good run SSEATR...One of my favorite cars on this site.

Thanks man! It is just the factory trans, I'm waiting until it grenades itself and then will swap it out with a th400
