[Fot] Suppose you were building a motor for your favorite sunday street car

[mark eginton]

Curious what people are happy with in a aggressive street TR3 motor for your
favorite Sunday street car? This car won't idle much, Upstate NY back roads
- Infrequent Track "club events" and autocross for fun, but no fender to
fender racing.

 

Specifically: is the TR4 head worth going to, I have plenty of TR3 heads,
would rather have the shelf space unless it makes a significant difference.
I may do some port matching but that's about it unless.

 

TR4A Cam or "D" Cam - have new old stock D cam from dads old stash.

 

Probably 87mm pistons kits from BP NW...

 

Pump gas and today's grade premium; what head thickness or compression ratio
can I get away with. 

 

Anyone got a rebuildable limited slip pumpkin in their stash; I accidently
threw one out when I broke a tooth street racing back in my teenage daze -
took me years to figure out why the car did not powerslide any more; live
and learn.

 

Any other thoughts, I have a lot of toys that I have to peanut-butter across
my discretionary funds; time is a little less of an issue.  

 

I accidentally sent a message meant for Joe to the group - apologies.

 

Looking forward to placing faces with email names and handles to many of you
this fall.

 

Loving spring!!!
