Very nice work, Greenman! But I don't think any of the GS vettes were fuel injected, the coupes I've seen all had cross flow Weber set ups. And I believe that the roadsters were converted to big block (427ci/7liter) engines with single 4 barrel carbs? Please correct me if I'm wrong.
QUOTE But I don't think any of the GS vettes were fuel injected
The Grand Sports from `64 on were cross flow Webers. However the Grand Sport project started in 1963. The `63 cars had the standard Corvette fuel injection on a 327 (L84, I think) early in the season and later in `63 they tried a Rochester fuel injection system. At the end of the season Gulf took the fuel injection systems and later sold them.
(man, it's great to have a good reference source).
QUOTE That is interesting Greenman, except that I am very sure that the production Corvette FI was made by Rochester (a division of GM). So I guess that maybe there was another version?
That would be correct. As you can see on the left is the FI that was installed on the original early 1963 season GS L84. It is if not the same unit that came with standard Vettes it's really similar. The unit on the right is a special dual inlet Rocester unit that was on the GSs at the end of the season... The ones that Gulf took and later sold.
Wow, I've never seen anything like that unit on the right. It looks very tall, does it protrude through the hood like a dual 4 barrel tunnel ram type intake? I am very interested in these because I work for a company that makes a mechanical fuel injection system for aircraft. It was originally made by Bendix and is based on similar principals to the Rochester system. It was also used on several Indy cars in the 60's and 70's, including the '70 and '71 Indy 500 winner. What book are these pictures from?
