I used a smaller flywheel on the swap what else needs to be changed.

I had to use a smaller flywheel and use a smaller bellhousing what else do I need I need to do before I can race my car. I just went out and bought a daily driver a 96 T-bird with 70k on it for $800 dollars. I now have a toy my stang so Iam going to do what I wanted to do is to go to the track and have some fun. I want to have my car setup the best I can by next Friday because that is my B-day and Iam off of work. I turn the big 19 and I just want to have fun. I hope to get low 9's I ran the car befor and it ran 9.8 with the 3.25 and the C6 in the 1/8 mile speed was 70mph

No my car rides smooth now no vibration at all. I put the flywheel in and the tranny. I had a C6 in there which had the big bell housing. I called summit and told the guy I had a 289 with a C6 and I wanted a C4 and told me to get the tranny with the small houing. So I did but the A- HOLE DID NOt know what he was talking about so When I went to go put on the housing it was too big. I got a new flywheel at my work and I think it is the 157tooth. I have driven the car and it is fine rides smooth.
