I was wondering how fast a 82 gsl with a s4 na engine, weber carb, exhaust and header would be. If anyone has this set up, let me now what 1/4 you ran.

 

I have a GSL-SE with a Holley carb and it's quite fast. an S4 should be even quicker. Get it well tuned and you should be able to run high 13's, definatley low 14's

dam, thats fast, my vert would never do that.

 

It would with a T2 conversion

 

it'd be running flat 12 with 380rwhp

 

I have a '74 4 port 13B, streetport, webber 48 IDA, RB full race exhaust in my 1980 SA. (see sig below)

Dynoed at 168 RWHP (with a high rpm misfire beacuse of bad wires)
So, say about 200 flywheel hp.

RWHP is a better barometer that trap times imho because 1/4 mi times are also dependent on weight/traction which you did not mention.
