1994 Chevrolet Blazer Sport Fullsize 383 STROKER project

Nice full size BLAZER SPORT 4WD 383 Stroker project
The engine was originally a 5.7L [350 ci] TBI swapped out for a 383 stroker.Balanced rotating assembly, Scat performance stroker crank, I-beam rods, Sealed Power 9.0:1 hypereutectic pistons. LT-1 hydraulic roller cam, all new GM valve train components. Edelbrock performer TBI intake manifold, Titanium coated Pacesetter shorty headers. $4000 build ZERO miles. This thing should have about 340HP but is a dog & runs like crap & I can't figure out why!!!! It pissed me off so I parked it.
The transmission is a BUILT4L60E transmission, HD input drum, Kevlar bands, "blue" clutches, 5 pinion planetary, billet servo ... $2,800 build nearly ZERO miles!
It has 3.73: gears & a towing/trailering package.
Interior is clean, high back buckets, center console, [same as the 454SS pickup]6 way power driver's seat,overhead console, folding rear seat, good headliner [not falling] Garnet Red.
Exterior is Black & Argent. Factory Aluminum alloy wheels. Tires are fair 265-70-16
Over $12,000 invested, great deal for someone with the ability to figure it out ..... I want to know what it was when you do .... Hasn't moved since 2011 so plan on towing or trailering it out.
