    If your car is already set up for a Gen1 SBC the simplicity of just building and installing something like this probably still makes a lot of sense (but with a much more cost effective carb and your existing accessory drive). If it's not, the power potential in an LS motor is hard to argue with. I'm not even an LS guy, really, but they are hard to argue with. Junkyard 6.0 plus cam and springs, for example.

      I'm 2nd owner of a '94 Silverado 2500 (6lug) 2WD Ext cab that would make an absolutely amazing sleeper with something like this in it, it's showing it's 30 years of use as an actual truck with crappy 90's GM white paint. But the swap would be pretty much a wham, bam, thank ya ma'am operation, a couple guys with some experience could easily have the swap done and started/running in 1 weekend.
      That old truck with 500hp through the 4:10 gears, and limited slip, would have some definite get up and go, while the TH700R4 would give it acceptable highway manners.

  • @jefferyholcombe5189
    @jefferyholcombe5189 Месяц назад

    Watched again and am interested in the TB that you used but in a version with injectors. If they don't offer it I am trying to figure out how to use the ECM that came in the truck and just run the injectors under the factory style TBI unit with the injection stripped off and some injectors, maybe 3 per TBI port on each TBI bore blowing into a TB spacer that is modified for injectors. I can control the injectors and timing on the Factory ECM so that is not the problem, just getting enough injector to flow enough when boost comes on and starts huffing into the blow threw hat. I had one of the last professional engine builders in my area build my engine and I was lucky enough that he said he would do it without a time limit and it would get done when he could get to it but he is the only one in my area of upstate NY 15 min from border that does the kind of quality work like you do! Hard to work out technical stuff when he retired for the most part. Hurley Machine, Danny Hurley is the man I had do the motor, best in our area!

    Can't make power with a 400SBC? We made 6-700 hp 406 and 377's before the nitrous in the late eighties. Now we have 100x more access to aftermarket parts. Better blocks, cranks with any mains and stroke you want, rods of any length, any piston you can dream up, incredible heads, super strong light weight valve train, hydraulic roller cams, and other cam technology we could only dream of back in the day. Nothing wrong with a 383, but it isn't what I would have built.

      Not really what he was saying. Obviously the 400cid block can be modified to make good power. What he said was how practical it is? Unless you buy a new block, there's more cost involved than needed for this build. Depending on core shift, and whether the cylinders will clean up at 0.30 over, or 0.40. I'd suggest at least a partial block fill. Who's gonna go that route to build a mild street engine?
