Here is something to think about, I just looked up the Moroso crankcase evac system and there was a footnote that said you shouldn't run this system if you run mufflers, which you do.

It's probably due to the back pressure????
i dont know what to do for breather ... PCV VS EVAC ???

Would help to get some more weight off the noise, 56% front, 44% Rear is pretty nose heavy.

John, on a street car, after relocating the battery to the trunk but without replacing window glass or removing stock sheetmetal, how do you do that ?

Same way you would on a race car. Remove everything that isn't absolutely necessary. What does have to stay, lighten it.

What I see in a quick glance - Power Brakes, convert to manual
Cast iron water pump?
Power Steering
Wipers
Inner Fenders?
Lighter wheels
Light weight brakes... etc. etc.
Aluminum Block

Guess it just depends on how stock he wants to keep it and of course budget.

It's a sweet car, serious consideration ought to be spent to leaving it the hell alone and cutting up something else if you want to get crazy.

The one thing that bothers me, and it might just be the picture, but those slicks look awfully close to the leaf springs.
So when will you be trying the new mods out?
How about some fiberglass for the front end, like a hood and bumpers?
Those who think they know it all have no way of finding out they don't......... :scratch:

Raffaele,

Ok, so it just occurred to me... :scratch:

You're running full street exhaust on the track, right ?

I see you've welded your crank evac tubes into the exhaust outside the collectors so this might pose a problem, but I would drop the exhaust & mufflers and run with open headers with maybe 12 inches or so of extension stubbies to provide a little back pressure for low end torque, but for sure drop the muffler set up.

Weight = HP, right ? And HP = ET :smt003

On my little blower car it helped on my 60' and was worth 2 tenths at the top end...
