Hello to All! I am new to the forum.... most likely 'Nuff said'... (<: I have attached a 'rough' spec sheet on a 402 BBC that I bought a year or so ago. Story is it was build by a Rod Shop and the Owner passed away and his wife put the motor on Ebay and a friend of mine bought it and I bought it from him. I am of the belief it is what it says it is. I am about to put it in a 'Body Off' 69 Chevelle, not original SS but I am putting ALL custom parts on it from the ground up. Complete new Hotchkis Sport Suspension, Hughes Custom 1000HP rated Trans, Wilwood brakes, Ford 9 read end, and the list goes on and on. I have attached a PDF that is the spec sheet that was listed on Ebay when the motor was sold. I am adding a high end EFT Holly in place of the Carb setup since I plan on making it a daily driver. Wondering, short of a Dyno test, if anyone would feel OK about Estimating what they think the HP on this motor might be. Thanks in advance for reading and helping.
