Ok thanks for the tip,
I can make some custom parts for big block and speed is not important in my case, I just want to back on feet this rc
I worried about is there enough space in my chasis for this big block? cause in that video the engine was placed horizontally and back of starter is open, but t15 is standing straight and the starter almost touch the rear swing arm.
For the t15, the length from the starter motor to the end of the gears is 110,2 mm and almost touch to rear swing arm
K5.9 is 112mm
Also can I put the existing pinion gear from the t15 to the big block to match the gearbox?
