So i'm back again about the 63' TR4. We got everything buttoned up suspension wise and got toe set . Been driving it got 200 miles on it in the last 2 days.
Anyway we pulled the timing up to top dead center and put about 8 degrees advance in it. However i was reading about new alcohol based gases. I DONT LIKE THEM and never have. Regarding Lead, some reading i did said that this gas was developed because of spark knock ( which we have around 2300 rpms right where is starts pulling good ). It reduces the tendancy for detonation. The car is running around 12:1 compression ratio, more around 11.5 maybe. Anybody use led substitutes with hardened valve seats and see that it reduces spark knock?
P.S. It supposedly raises the octane in some strange way to prevent detonation. Using racing fuel it no longer runs of after shut down and will pur like a kitten up all hills.
