Hey there, this is my first post, though I’ve used this forum for every issue I’ve had. You guys are great!
I just put a 331 stroker into my 89 Foxbody. All forged internals, earson heads with 1.6 rockers, earson cam, edelbrock performer 2 upper and lower manifold, factory fuel rail, 30 lb trickflow injectors, 255 fuel pump, BBKcalibrated mass air for 30 lb injectors, bbk shorty headers with bbk h pipe and cats and factory computer. New tremec tko transmission with McLeod flywheel and clutch . My question is I plane on taking it to the dyno and getting a tune with a sct chip, but I would like to drive it around a little to make sure everything is working before they do what they do. I’ve changed out the breakin oil with 10-30 for now and my machinist says he would fire it up and take it to the tune shop so I don’t wash out my rings...I’ve smelt the oil constantly LOL and dose not reak of fuel. Can I drive this thing without a chip/tune ??? I’m in no way going to beat it up but would like to put some miles on it before I send it . Any thoughts ?

As long as all the electronics are calibrated for each other you'll be ok. Just not at peak efficiency and obviously you'll be guessing your hp and tq numbers.

I live in the middle of nowhere lol the nearest reputable tune shop is 2 hours one way and it’s gonna be an expensive tow. Also with absolutely everything new I kinda wanted to break my clutch in before they beat on it on the dyno

They won't beat on it. They'll drive it up to 5000 - 5500 rpm a few times. If it was me I'd drive it straight there. I drove an hour and a half for my tune after learning it was a 'Bama tune.

Please be sure to follow the break in procedures for the clutch. You must complete that before taking the car to a dyno. The harmonics on a dyno can keep the clutch from bedding. Please follow this link to our instructions. It does not matter which clutch you purchased - the break in procedure is the same. Thanks! Any questions please call our tech dept.at 714-630-2763 or email them at info@mcleodracing.com.
