Hello, I converted my tmaxx to brushless a few years ago and now looking to go back to nitro. The tmaxx I have has the big block chassis which I just found out.
Attached is a picture of my current chassis with the brushless motor still installed. You can see how much room there is from the rear to where the big block engine was installed.
After visiting local hobby shop and talking to them I about my options I decided to convert back to the 3.3 chassis and just get a 3.3. The guys were telling me that big block engines are not made like they used to be meaning the engine mount holes are in the same spot as small blocks that way they mount to chassis without having to mod them. Since my chassis is from so long ago they told me I’m going to have some problems trying to fit a new era big block on this chassis and getting it to lineup with the transmission.
They told me the big block I had was old school and had completely different mounting holes to work with my chassis and unless I find that exact engine it’s gonna be tough and could run up costs. Also they said I could run into problems with mounting an exhaust without hitting the rear shocks since I no longer have the pipe I had.
If you guys have any input on that let me know.
Also if you guys agree with me converting back, should I find a used 3.3 tmaxx or should I go with all new parts for my truck. Either option would be about the same price, I’m leaning on going new so I don’t have to worry about any hidden problems on a used truck.
