I think extrude hone is not allowed.

Not sure what I may have indicated in my post, but the manifolds are stock and not ported.

My post was unclear, I was indicating that yours are in spec, and even extrude honing is not allowed.

Good to go.

those roller rockers have to go. they're not legal for pure stock drags.

<span style="font-style: italic"><span style="font-weight: bold">Valve Train:</span> The valve train must be factory stock for the year, make, and horsepower claimed. Rocker arm ratio must be correct for the year and horsepower claimed. No aftermarket rocker arms of any kind allowed. Stock stamped steel or stock cast iron factory rocker arms only.</span>

Some buddies of mine are hardcore pure stock racers. They are making more hp with stock rockers than they are with all roller rockers except one particular brand and part #, so might actually make more power with stamped steel stock stuff.

I'm waiting for parts before I can really progress much further. The air cleaner is mounted, fitted the ignition shielding as well as installed the left hand exhaust manifold. I am going to wait until the car is running and I am happy with the injection before changing the rocker arms.

Just a suggestion learned from running these early Vettes hard, but you'll probably want to put some grade 8 bolts in the water pump/ motor mount attachment to the block. When you start racing the car you will have to check them frequently for being tight. Put some spare water pump gaskets in your track tool kit too. Use the thinnest gaskets you can find with very little or no sealant. Otherwise they will just squirt out and leak. [img]<<GRAEMLIN_URL>>/burnout.gif[/img]

Good point. Advice taken!
