small block and big blocks are going to have different size openings, I'm inclined to agree that header definitely looks like its Big Block-1/8 scale application.
might be able to look into a nitro 4-tec header?
the exhaust pipe(muffler) looks like it should work just fine.
as long as it runs...
Good! i was kind of in the same scenario last night, was working on my friends Nitro RS4 2, the clutchbell rides on a long roller needle bearing (https://www.ebay.com/p/HPI-B046-Clutch-Needle-Bearing-5x8mm-Discontinued/1000194506?iid=293031918313&chn=ps )
instead of separate ball bearings like...
the biggest thing with doing this is to get the depth correct for the gears to match up, front and backwards then slotted for side to side to adjust mesh against each other. you want full teeth on teeth, not half of the teeth on the cb to hit the spur.
and id definitely look for what @cbaker65...
think that was one of those weird engines where just the case bolted down before case mounting holes were standardized. or just might have been a one off, but looking at the engine the mounts are casted on the crankcase.
that case would probably drill the chassis out but try to find a thin piece of aluminum as a reinforcement plate, shouldn't need it but just extra rigidness.
personally id say engine mounts, that car is pretty rare so having a clean straight chassis would be pretty important (IMO anyway) unless you can find another chassis plate to have as a spare.
i have yet to run an on road car of any type really, so i am very excited to help my friend get set up (he is brand new to nitro, but has some electric experience). i can only imagine the difference between the gx.12 and that cen, even just for the fact of having 2 needles.
for drifting i know...
that one has me, I'm going to imagine for the clutchbell that you are going to take off the pilot from the crank as i think the one in the kit is extended, the other I'm guessing that you are going to be tearing the rear diff off as it looks like the kit includes a lengthened input shaft for the...
