Been a journey. Hope you have some more pics coming soon. Mad Props to making it happen. Love the idea of upgrading. Cheers to you. Sent from my iPhone using Tapatalk
Figured I should post an update, I have put a couple thousand trouble free miles on it at this point. So to sum it up 355 engine, 355 6 speed, 355 rear craddle so all 355 rear suspension. I'm running a Haltech R3 standalone ecu which is also a power control module so I've slowly been running more and more of the vehicle functions off the ecu, eventually probably going to just eliminate all of the factory 348 wiring and have everything run through the ecu.

I know it's rare these days haha, but I typically do what I say I'm going to do. Financially I probably should have just fixed my stock engine or put another in, but it's definitely faster, makes better noises, and it's nice having an electronics system that isn't temperamental and ancient.
Have to say I think you made a great decision. Nice work! I'm curious if you have ran it on a dyno? I've been modifying my car as well and had some thoughts about shorter/straighter inlet stacks. Or, do you see any drop in map kpa as rpm increases to redline on a data log? At least then could know if the throttle body/blade size is a restriction or not. Especially on this setup with open/short/straight inlets.
Please share details of the stand alone process. The 348 drivetrain is pretty solid, it's usually an electronics issue with our cars and a stand-alone ECU could drastically change everything.
I havent put it on a dyno yet, I do actually have a couple different sets of velocity stacks and do plan on trying different sets to see what affects it has. Unfortunately it's a bit of an odd size for velocity stacks however so there isn't a very big selection and nothing really that goes on without some sort of modifications, my neighbor has a cnc lathe and is eventually going to make me some 1 off ones.
Just have to build an engine harness and figure out sensor compatibilities and such then obviously figure out what the pinouts are for the car chassis plugs. I have built alot of engine harnesses over the years for myself and customers when I worked on cars for a living. My car works like factory with all factory gauges working.
