part number 2101 is for "Chevy 262-400(non-egr)", that would also be for the 86 and earlier style heads, (will not fit 87 up centerbolt heads..that'd be pn 2104)
on that motor, bore and such doesnt matter, if its a rebuild it should say the bored out size on top of the pistons.
i just want to try to figure out the approximate date of the engine.
pre 79.. *edit*(oops duh, i need to check my typing) 2 (not 1) piece rear main, oil dipstick on drivers side
80-85... *edit* 2 piece rear main, oil dipstick on passenger side
86-up...*edit* 1 piece rear main seal
87-up had centerbolt heads
the roller cam engines have three bolt holes in the center of the intake valley
I could come get it sooner then 3 weeks, just let me know where you're located so i can see how far it is. Thanks and i'm in no rush for this info so take your time. -paul
