my 81 350 with manifold,modified 650 holley,actually flowing 780 cfm,1 5/8 headers,small comp cam.stock heads made 205 hp at the wheels.
Ive fixed that problem
That cam on a Vortec 350 has been proven MANY MANY times to end up in more than 400hp- flywheel though, not rear wheels.
And as noted HEADS are the most important part, as such I would not get those Edelbrock heads, for the same price look at some Jeg's or Summit house brand heads (Jegs are Profilers, Summits are Brodix).
If you don't have the carb you may want to get a bit bigger one, a 750cfm carb will have no problem.
