okay update-engine runs fantastic. On mine I will need to change rod at 1/2 gallon. I may have caused most of the problems by taking engine apart/cleaning but not resealing like I normally do. I received a pm]not from trey] that I may have gotten a engine with tighter tolerances. when you get yours I will say it is plug-n-play.The fit and finish on the engine overall is second to none. I would recommend that you do heat it up to a good 240ish before you even attempt to run. Thank you racer-22 and Nitro North.
On to the engine it's self. I will state right now this is the first and only GO-TEC engine I have ever owned that runs great on 20% nitro. All the rest of my go-tec's mg-66 ran good on 30% nitro. 2nd it is powerfull and super smooth. And I am only on 2nd tank 1/4 throttle. It want's to pull hard but not rip the tires off of the car. So I will keep updating as I continue the break in process.
1 last thing this will be the engine to have hands down. I just wish I had the money to start my go dealership. But I do love the new leg brace/walking is important.
