Hi

I am a Wild West German so Sorry about my English.

No here is my Question. I have a 84 G20 Van with a 305 Engine for daily driving. The Engine is in bad Condition and now I rebuild a 400 Small Block from a 69 El Camino. The Engine is ready now with new bearings, Piston Rings, High Volume Oil pump and Edelbrock Performer Cam.
I would like to use the 305 Heads on the 400 Engine. Is that possible or is it to much pleasure?

I will use a 600 Ede Carburettor , Performer Manifold, and Headers with a dual Exhaust .
