1969t rebuild - Cam question
Note: This is a repost of my question from the "Engine Rebuild Forum" Sorry for the duplicate post, but I thought it would get more exposure here.
I am in the middle of rebuilding a 2.0t motor from a 69. I have the following parts ready to assemble: 2.2t heads 85mm pistons/cylinders 9.8/1 CR 40 webers SSI's Larger pulley I have both Solex and E cams This is a very mint car that will be used exclusively for street use. 1. Which Cams would you use, E or Solex? 2. Considering there is no oil cooler, any heat issues to be concerned with? 3. Are the 9.8/1's a concern? Should I reduce the CR? I was originally planning to build this car to 2.2 e specs, but the cylinders were out of spec and I couldn't find any in spec, so this led to ordering the 2.3 setup. Looking forward to your thoughts. Best Regards John

The only potential problem is if the cutouts on the pistons are deep enough for either the E or Solex cams. I rebuilt my 69 E with J&E 86mm pistons 9.5:1 ratio. But of course I spec ed the pistons for the E cam I had so the pistons fit nicely. If the pistons were made for your T cams then you may have clearance problems. Hope this helps.

jstobo - Wow, missed your response from earlier this week. Sorry for the delay, but thanks for the post. The pistons I ordered are 9.8:1 JE and are set up to work with S, E or Solex. I am using Solex, but wanted to know if someone could give me a compelling argument to use E instead. I understand what you are saying about the T cams, but fortunately I have other choices. How do you like the E cams with your setup?
