Patrick:


I do believe that in some cases bigger is better but not all since I am only 
5'5''. Your solid guess about the weight of my Engine and weight ratio is 
way off.  Try looking hotrod magazine for specific weights of engines.  I 
have them in the US and will forward to you this summer.  For now this will 
have to do.

First the Spitfire engine is a heavy casting using old casting technology.  
The Chevy V-6 is only about 75-100lbs heavier even when using the cast 
intake manifold.  By using an Aluminum Edlebrock intake and moving the 
battery the rear of the car my front to rear weight ratio is about 50/50.  
This is a better weight ratio than the stock spit.  Also another factor my 
Borg & Warner T-5 transmission and bell housing are Aluminum not cast like 
the Spit Tranny. These are facts so the weight ratio is actually better in 
my Spit than a stock Spit.  I still have a stock Spit to compare things to.

I will race any spit in the 1/4-mile or a road course.  The rear suspension 
is out of a Datsun 510.  It is totally independent and does not have the 
problem of the tires tucking underneath the car in heavy cornering like the 
spit causing excessive roll.  As I mentioned before I have owned about 15 
Spitfire and have been driving them for about 20 years so I know how a stock 
Spitfire handles.

As for my bonnet my project has well planned and executed.  Keeping the 
engine as low to the ground as possible gives you better center of gravity 
and handling.  You already know this from your racing experience. By 
planning this out properly there was no need for hole or scoop in the 
bonnet.  The little Chevy 4.3L V-6 is nested under the bonnet.  I will be 
more than happy to send you some pictures via email or anyone else that 
would like to take a look.  The car was also featured on the front page of 
the auto section of the Syracuse Herald Sunday Paper this past August.  It 
has a half page color picture of the little beast.

In the early eighties until 1992 I had a Capri 2.8 V-6 in the car.  This was 
heavier than the Spit engine and yes the carb stuck out of the bonnet.  My 
project has come along way since then.

That is one the best things about owning a Spit you can buy them cheap and 
be creative.  Everybody has his or her own approach I like to be a little 
different.  Like I said before I agree that putting a small block in is 
possible, but overkill.  But again to each their own.
