[Ronj1969]

Just replaced my Saginaw 4 speed with a Muncie and a set of head gaskets and trying to find a good spot for the timing. Drive it for a bit and seemed to have some detonation under acceleration so I put 5 gal of e 85 and 4 gal of 89 in it trying to get about 95 still seemed like a little detonation so went to back of the timing but she is running like **** ( was before the e-85) the idle is all over trying to adjust it doesn’t really help. As it is so sporadic at idle. I tried to post video but it won’t let me
