I have stock jets in it now, which I estimate to be 85s in front and 74s in the back. I'm estimating that based on a set I have in front of me now, which are 87 and 76. I had tried to jet it up in the past, and I seem to think that I went up 2.

Interesting that you mention no jets in the back. I've never heard of that concept. Of course, I haven't been around a race track for years.

So, I'm going to put in the 87s in the front, and see what happens.

I'm waiting on new aluminum collector gaskets to come into the auto parts this morning. I had one blow out on the right side. As soon as I get that in, I'm going to experiment with advancing the timing more, and the jets.
no jets in the rear is about the same as putting the biggest jets you can buy in. just save the price of he jets. i think 92's are the biggest.
