looks like its taking shape quite nicely!

is it for some form of racing ?

[Grim304]

drag racing initially but will likely do a few hill climbs and club days, speed events whatever comes along,

I had a chance to get my VR SS Auto on the dyno today and was impressed with the flat line for HP but still want more breathing.
I am about to change my intake manifold so I can attack my original and see if I can make a better one.

Well I have started on the right track to build a Street Happy Fun V8, it was running 14.3-14.4@98-97mph all day long without slicks and with no changes to how it's driven on the street.
The next mod will be the interesting one as it will be the intake manifold.
165kW at the wheels is ok for a stock dished piston 9.3 compression 304 but it's way short of what it can be and I will continue to tinker until I get the kW over 200 at the wheels.
I am still focusing on this performing about 1 second quicker in the quarter but it may take new headers and roller rockers to get it there I think but I am trying to get as close as that as possible without them.

try slicks first then it'll probably give you the one second

and valve springs will help that powercurve emensly

[Grim304]

Slicks would slow me down further and Valve springs have been done and should be good for 7500rpm all day

The tires do smoke a little especially when I hit 3rd gear in the burnout
These things, I was told by the guys I have bought my tires for the past 10 or more years, would smoke but give good traction and they are right again!

did you play round with timing on the dyno

[Grim304]

did you play round with timing on the dyno

Yep, 11 runs and each one was a little tweak on fuel and spark
