how to properly measure a sc pulley



Used a set of dial calipers, going back over to the garage today to work on my engine , ill look harder see if there is any numbers , I do know this , much smaller looking than stock
 


It has a set of diamond pistons , headers , gonna put colder plugs in it , and a fender cold air intake , motor is tore down to the short block , think the ecu has been tuned also , stock cam , and I'm gonna port the heads a little bit , run a 160 stat
 
Diamond pistons - waste

Boring block - waste

160* - waste

stock cam with ported heads - waste

not knowing if it is tuned or not - more of a problem.

My suggestion. Go get the PO and find out WTF is going on 110%.

Then, go buy a stock short block, stud the heads, re-gasket and get new fluids, port the heads, run a cam of some sort because porting the heads with a stock valvetrain would be a waste. Start off with a 3.4" pulley and go from there when you have a way to tune it, because a 3.1" will be too small. Probably running the factory injectors static as well which is no bueno.

So yea

Only if you don't know the correct steps.

People just slap it in and the reason they don't stay together is because 100% of those 90% don't line bore the mains...which kills the rebuild...making it a 50 mile winner.
 


Well engine was gone through about 35k ago , I just opened up to check the mains and rods , make sure they was ok , no abnormal wear or anything like that . I am a tad old school , built a few engines in the past , mostly Chevy 350 . Just didn't want to get this engine in the car and have a knock or something internal wrong ya know . Gonna put new gaskets , plugs and what nots , tore heads down last night , gonna take off the casting flash in the runners and blend the bowls . But the engine has has the headers , pulley , and pistons in it for 3 years or so and everything inside looks to be in good shape
