If you read National Dragster, this is interesting S/SS!

If memory serves me at all, the final rules in Top Stock for the 360 Mopar, which was a crate motor, was about 13 to 1 compression, .600 cam (still the cam we use) hydraulic rollers (which we still use), Edlebrock heads and we were allowed the runner volume for a Bow Tie, any cast manifold, an 850 race carb, any springs, 9 inch tires and we were about 2900 lbs with the driver. The DP motor uses the 847 Mopar heads (knock off of the Edlebrock), we lost the domes on the pistons (about 11 to one) , we have .490 lift in Stock, we now have roller rockers in stock, (still using the same ones), and of course much smaller runners than the Bow Tie heads, and the pistons are 100 grams heavier than Top Stock for Stock Eliminator, in Stock uses a stock M1 manifold which has been around for years). It's not as good as an Edlebrock. And of course EFI. There will be a test tomorrow on this, so study for it. One interesting thing on this whole mess, when the 360 specs were listed, we took the old motor, machined the domes off, sent the manifold back to Wilson for EFI bungs, changed the heads and made it a GT motor. Put the thing on the dyno, fair, so at the end we threw the 850 Quick Fuel back on the thing. Made about 15 more hp. Called Wilson, and found out the carb will peak higher because of the atomizing fuel in the venturi as opposed to the injector at the base of the manifold. When Nascar went to EFI, the injectors are just under the throttle body. Interesting.
