Is my engine dead?

Thanks Ramcharger! good advice there.

I looked to see what the cost of parts are for the 318 and it's so cheap it's not worth not doing. I've rebuilt many a small block chevy and it's nice to see parts cheap.
Being from alaska, this truck has all the essentials- block heater, tranny heater, battery heater, and one more I haven't traced out yet. This things ready for buffalo's battle with snow. Just needs a tight powerplant to make it go.

one more question though. Is the thermoquad worth using? It's been rebuilt already and ran great before i'm told. I'll probably end up ditching the cast manifold and go with something aluminum like edelbrock, and a holley carb with manual choke.

thanks again!
