I am ready to order an engine for my '85 K20 Sub. The problem is I don't know what to get. I'd like to stay small block for installation simplicity.

I plan on using an auxillary trans cooler and oil cooler along with a good aluminum radiator and electric fan(s). A 2" lift with 33's will be the setup choice for suspension. It has 3.73 gears which may or may not get changed to 4.11s. The tranny is a 700r4.

I will be towing some, boat camper, etc. I don't want to hamper any towing abilities I want to enhance it.

How much power is enough (I know, never enough but I need to save some money)? Wasn't stock 160 hp? GM crates has a 350/290 that delivers over 300 pound feet of torque starting at about 1600 rpms. Will this be a good engine for a burb? I can get it for under $2000.

Will a 350 be enough or should I step to a 383 or even a 400? I have been cautioned on the 400 that they can be touchy on cooling. Is that true? A 383 is quite bit more than a 350, bout double.

This is the first Chevy I am doing, so I need some help.

Thanks guys
