What you all just expressed was true on my part. I started with a manufacturer supplied 1776 with my VS. If I had known a little more at the time, I would have at least opted for a good case, balanced crank and legit cam. As it was, I sheared the cam gear at 3,000 miles at 3700 rpm, with zero abuse and max TLC. It was a Mexicrate Hydraulic Valve 1776.... so when valve train stuff went flying I was faced with a complete top end and also had to split the case. So, I opted for a new AS41, CB044 heads, E110, Scat Crank and the works. Then I played with carbs and ended up sticking with the ICTs for that build.
My point here is: it is worth your time & money to do your homework (as the thread opener is doing) before buying anything.
We all have our ideal engine. For me, it appears to be a 2110. That comes after mucho private mails, reading the archives, and learning from others, including talking to builders, especially CB. I am not a master mechanic, nor do I claim to have the total picture on all of this. I can turn a wrench and do most of the basic stuff though.... but overall I am just a driver/consumer. So, my choice was based with that in mind... I wanted a good solid driver engine. For the extra bucks I went with a stroked 2110 engine this time... in a solid, but not radical CB build. I was tempted to go with a 2165 as I know Dale has driven his a bunch.. (as have Vince, Paulie, and others on this thread.) and I think it is a very smooth stroker. I settled for a 2110 as it fit my overall car build and planned use.
There are very few wrong choices... as long as you know what your driving needs are, use good parts, stay with a standard CC Combo and use a good reputable builder.
Again, I think once you get your engine selected you should look strong at your gearing. Some use a 3:88 or 3:44 R/P, and others swear by a stock R/P and going with a freeway flyer 4th. Again, we all have opinions there, but it is essential that you choose something that works for your 75% highway driving. You might check last month's issue of either HOT VWs or Trends on the interview with Tranny builders. They address your need for a highway car...(they all have a different approach).
Paul is right... getting an engine geared and also built to be running at 60-70% at highway speeds is a trick. Having that extra horsepower and torque was the reason I jumped to a 2110.
Paulie also mentioned a T-4 and they are a good option from what I read (never owned one, Paul has!). I looked into FAT and others. They have some neat options for what you are seeking. As with all TIV builders, get out your checkbook. They are not too expensive, but they are definitely higher $$.
I am not an expert... just another owner sharing an opinion. I would call some builders and also watch who drives a bunch. There are a quite a few out west... Eddie, Bruce, Stan, Vince, Scott, Paul, Dale, Troy, Ray, Rick, John's H & L, and a bunch I haven't mentioned. Check with these guys privately and see what they recommend. The cool thing about the list of names? There are 1776, 1915, 2110, 2165, 2332, and T-4 plus Suby owners in that line up. There are others.. I just mention these as there is a variety in engines used, but all of these cars get driven.
