Engine Identified! Anyone know specs?

[klink70]

In my previous thread I needed to identify an engine. With the help of Mortec.com and the block casting number I got it figured out. The 10066036 casting # is a Target Master/Goodwrench 350 crate engine of the years 1990 and up. They came in a 2 and 4 bolt configuration, mine being a 4 bolt, with a 2-piece rear oil seal. They were or are "Hencho En Mexico"....Made in Mexico. From other sites I've found out some other info.This engine is a 250 horse, 8.5 to 1 comp., 76cc 993 casting heads with 1.94 intake and 1.50 exhaust valves, with a 929 cam...whatever that is! I plan on rebuilding it for my '94 daily driver/work truck. I'd like to up it a little on the cam side without sacrificing mileage. I'd also like to keep the stock throttle body unit intact from the '94. Can anyone tell me if this is possible? A different site said the intake bolt pattern was different, but I measured them, and they looked the same. Does anyone know if the specs for this engine are the same as an actual factory engine? I believe this engine is a '91 vintage and the specs in my manuals for years '88 thru '95 are the same. What would be a good cam for my application? The factory cam specs for an '88-'95 350 are 0.2565 intake lift and 0.2690 exhaust lift. My manual doesn't list duration or lobe separation. I've rebuilt Fords and Poncho's before, but never a small block Chevy. Can anyone help me out on this? Or if anyone has any other info on these engines I'd greatly appreciate you sharing it with me. Thank you.

88' to 94' are about the same. I had a 91 and had a crower RV cam put in and it helped drastically with pulling and low end without lose of gas mileage. Don't know lift and duration though. Also it didn't affect any of the other engine components
