time to rebuild the 170..

Post #1 by falcondave63 » Wed Feb 11, 2009 5:56 am

before the end of car show season last year the falcon's 170 would hesitate under acceleration and the idle would hunt fomtime to time. i went through the bolts on first. the carb is new and adjusted properly. timing is adjusted properly..advanced as suggested. the air filter is new (k&n) plugs and wires are new as is the fuel filter. this led me to do a compression test. all were pretty low. #4 was the worst at around 90psi. the others around 110-120psi. adding oil to #4 only raised the compression a couple psi..valve problems i suspect. so with that in mind, my plan is a full rebuild. i cant see freshening up the top end without touching the bottom end. i plan on yanking the engine, ordering a new exhaust manifold (rear ear is broken off), having the completely head re-done with all new valves and seats, valve guide seals etc, i'm going to hot tank the block and paint it. i'll check the main and rod bearings, i'll replace all rings on each piston and supply the engine with a complete array of fresh gaskets. my dilemma is where to get all of the parts. i need to find a reputable supplier of quality parts. whats brands have you guys felt were top notch as far as engine rebuilding is concerned?

8) federal mogul, trw, speed pro, all are good parts to use for bearings and rings. as for pistons, speed pro and trw are the best imo for the street. that said however, most of the "white box" parts start with the name brand base stock. for example, badger and triplex pistons start with trw blanks and those companies do their own machine work. fel pro makes the best gaskets imo, and all these parts can be purchased at most any auto parts store, like checker. if you have problems getting parts from there, get PAW's catalog, check out this link;

Engine Rebuild

Post #6 by champion2211 » Sat Mar 14, 2009 8:19 pm

The first thing is to tear it down and see what parts you need. Has the engine been bored? Has the rods and mains been resized? You need to look at all the parts first to determine what the sizes you need. A reputable machine shop that does the head will check it for cracks and the seats and valves. I have already gone through this before and it is important. Good luck.

the engine has never been opened up. at this point in its life, i think it will need to be bored 10 over at maxiumum. i do need to replace the exhaust manifold as an ear has cracked off. i hope to get it out of storage and into my shop within the next couple of months. a friend of mine runs a very successful machine shop that specializes in sprint car engines. i have had nothing but excellent dealings with their staff and am confident that they can tell me what i will need. i'm considering installing a very mild cam just for a hair of extra low end grunt. this is however my baby and is 100% bone stock and i would like to retain that as much as possible.
