What can I expect from this engine?

Just finished my first Mopar - 360 + .040 KB190 pistons, Racer Brown ST 21 solid cam, Std "J" heads but with 1.96 & 1.60 valves,decent springs and 273adjustable rocker gear. Also has an old Vertex magneto and a toilet style mechanical injector. It's a very basic budget deal and will be running methanol in a slingshot dragster -904 TF 4800 stall converter, 4.30 gears and a 31" slick.Read a few books looked at the web - including some here, and applied a life times experience and I hope it works out OK. Ready to fire this thing up for the first time in a week or so. What can I expect from this?
Cheers
