this is directed to the guys who have done their own rebuilds. how many of you have the assembly balanced and who do you use to do it. thats my only concern about the build so im tring to get some more input. thanks in advance.

 

Not I. No need for it unless you plan to regularly spin it past the stock redline of 8k, and have all the other mods, such as a bridgeport or peripheral ported engine .

 

thanks for the input.

 

what will u guy update if u take the engine out and rebuilt it

 

apex seals, corner seals, new gaskets and few other minor things, other than that im not doing anything else. i thought about doin a street port but i dont feel its needed to reach my power goals. the car has an rb exhaust, 3" mid pipe, 3" down pipe, pt61 turbo, power fc, wahlboro, 1600 cc seconday injectors, 850 primaries, greddy 3 row innercooler, thats really it for the hp things. its nothin fancy. the last time we did a compression test she was gettin real low and since its goin to be in the paint shop for a few weeks i figured i just do a basic rebuild.

 

i'll be selling a good shortblock next week... if your interested in some extra motor parts pm me
