The best way to backflush a radiator yourself is to remove it from the car and use your garden hose to wash it out. Turn the radiator up-side-down and insert the hose into the bottom outlet, wrap a rag around it to seal that end, then turn the hose on full blast. Shake the radiator around to help get any crud to come out the cap opening.

You can also remove the thermostat cover and do the same process to the engine block and the heater core.
Prestone sells a backflush kit that helps you do a backflush without removing the radiator but I find that it is hard to get the big chunks to come-out the top when using their kit.

Erik,

Maybe I missed it, but did you post the buildup specs of your motor? No hurry, but I'd like to see specifically what you used.

Thanks,

Lou

Lou and all,

Engine buildup:
68 225 block and head
Bored 30 over
Head shaved 90
SBC Valves - I think they ended up 1.72I/1.50E
340 Springs
MP 268 cam
Silvolite pistons
Stock rods
Cox bros true double roller timing chain (what a thing of beauty) installed with cam advanced 2 degrees (per one of Doc's old messages)
J&M windage tray (figured I'd do it while everything was open (another thing of beauty))
Clifford 4bbl intake
Edelbrock 500cfm carb (stock jets, may need to do some playing but seems to be working okay)
Clifford street rod headers
Dual 2-1/4" pipes from header out w/ Flowmaster Delta 40's
10" Midwest verter (per Dennis' specs I think (stall around 2500)) (also a thing of beauty)
Stock 904
and finally (I hate to mention this part) stock 7-1/4 rear w/ 2.76? gears

To be done someday soon I hope:
Disc brakes and 8-3/4 w/ 3.55 gears (Should have done this stuff before the engine, but stopping is overrated).

Thanks again to all who offered me advise along the way.

Erik
