Thanks for the fast reply, Pat. Edelbrock recommended the 2161 performer manifold, supposed to be a good low rpm high torque piece, well suited to my application, what do you think?
*How well will the combination work if I keep the stock cam / timing set as opposed to an aftermarket cam? ( the numbers on the back of the cam are2296-9033 )
*This is a very low mileage engine and I can't find any reason for it to have bent 2 exhuast valves, #3 & 5, all the pushrods are straight, rockers, springs, retainers and lifters look good , the marks on the pistons are <.020" deep, so it didn't kiss it very hard, what am I missing?
*I picked up a rebuilt HEI from NAPA, how do I tell what gear is on it? is there a part number stamped on the gear, or do I just order an iron one from the dealer and change it?
*Can I run the stock dampener?
* will the SBC flex plate / starter work?
* will the SBC pulley's and brackets swap to the GEN VI ? the truck has Hydra boost and AC.
* Which water pump?
* would you change to an electric fan, or just change the shroud and run the SBC fan/clutch?
* for my application, would you run stock manifolds (with 2.5 " pipes/mufflers) or change to headers. ( I had hookers on the SBC for a while, but went back to the cast iron 'cause the header ringing gave me a nasty headache on long tow's)
* Are urethane motor mounts a good choice, or go with new stock rubber ones?
WOW, I didn't mean for this to turn into a book, but I really appreciate you taking the time to answer. The Vortec world is all new to me and still very confusing, thanks for taking the time to teach... Paul
