thunder bolt 4 coil
Is there anything special about the TB4 coil ? Can I replace/ substitute with msd coil and keep my Distributor and module?

Re: thunder bolt 4 coil
I replaced mine with MSD and kept the old one on the boat as a spare, just in case.

Any benefits to the MSD over the TB4? I just bought a boat with slghtly built small blocks and TB4s...Thanks

Re: thunder bolt 4 coil
the msd has stronger current which translates to better burn

Re: thunder bolt 4 coil
On my 383 I swapped the Tbolt coil that I was told was a 40,000 volt coil for a Jacobs 60,000 volt coil. It looks nice but did little to nothing for performance, 90% of the engines just do not need the extra zap. Tbolt is pretty decent setup don't let anyone BS you.

If you use an MSD coil make sure it is the 'high vibration coil' or it will not last long. The only time a coil change will help performance is if the old one was weak.

Like my Uncle Melvin use to say "You don't need a forest fire to light a cigarette, when a match will do".

Re: thunder bolt 4 coil
thanks guys, the one I have has physical damage. It works well but I'm not sure if it's working as well as it could.
