I have a 68SS and put together a 355 and have always had issues trying to start it when it was hot(headers). It was a crap shoot if it would start. I even installed one of those MAD remote starter solonoids on the inside wheel well and I still had hot start problems. So I finally decided to spend the money on a light weight gear reduction unit. I installed it about a couple weeks ago. Boy, did it turn the engine over fast. No heat soak issues either. I was a happy boy :beers: . Well, yesterday I went to take it out and take my boys with me. So I started it up pulled it out of the garage and shut if off. Went to start it, nothing..... Not even a click. So the next day, I try to jump the MAD solonoid ( which is a ford type) no luck turning the starter over. So I go and get a new solonoid, put it in and the starter turns over but doesn't engage. Great I must have something wrong with the starter now. So I put in the old GM starter and the car starts up and I go back to the speed shop and get a new starter. Put it in and it still doesn't engage the flywheel. It just spins. Put the old GM starter in it and it starts right up! So I am a little perplexed with this problem. I am thinking something is going on with the solonoid, I just for the life of me can't think of what? I am wondering if anyone has had a similiar problem. :clonk:
