Title: Byron Barker Magnum Mods
Post by: Tim Wescott on January 30, 2015, 06:32:26 PM

So what did Byron Barker do when he got a poor defenseless Magnum engine in his hands?  Did he just do things to improve fit & finish, did he massively change timing, or something in between?

(I'm wondering on behalf of my Byron Barker Magnum 52, which is currently sitting next to my workbench, watching its new home being assembled).

Hi Tim,

It has been my experience that Byron generally worked with the ports to increase the blow down and increase the 4 cycling capability.  Can't say if he did that on every engine, but on the ones I have had from him.  Didn't seem to kill off power and made them more consistent.

Thanks!

My Thunder Tiger 40 that Byron did (#104) has "Hemi" scribed on the head. Is it fair to assume that if he did hemi the head, he marked it?  One way to find out....

Hi Tom,

Yes, if it is scribed on there it is a hemi head.  Several of the engine workers do that, but not all.  Some do not mark the engine in any way.  And others vary in their markings.
