$1000 valve covers????
LOL, thats kinda crazy, If you've got that in the valve covers you must have atleast 20K in the rest of it.
I wasn't trying to sound combative, but what i was trying to say is that If the Block, crank, pistons, and rods are all still together and were in excellent working order when removed from the silverado. Why not leave it together and use it the way it is if your on a budget. plus then you don't have all the machine shop work to be done. change the cam and through some good heads on it with a good intake and decent carb, and he'll be at or past his goal of 300. The holley systemax kit sells on summit for $1700 or $1800 on summit and it includes everything but the carb, and its advertised at over 400 HP. I don't think that its gaurentees to reach that amout but prolly pretty close, especially with flat tops.
