CE Block crankshaft and piston
« on: December 16, 2019, 02:27:34 AM »
Hi,
Are these correct for 1969 Z28 CE warranty block? It is standard bore, the pistons have no numbers and the crankshaft has one notch.
Thanks, Terry

Yup, that's an 1178 crank by the notch, the piston number is cast on the underside of the piston (under the dome). Should be L2210A, TRW.

Steve

Hi Everyone,
Without taking the engine apart, does the photo showing the top of the piston point towards an original piece? This block does have the correct 1178 crank. Thanks, Steve for the verification.

Hi Jim,
The photos you provided look identical to the two I posted. My CE is a late 69 date code block. Thanks for posting.  :)

The 1178 crank mandates the use of the L2210A piston (or any other manufacturer's 302 piston) due to the pin location required when using the 3.00" stroke crank with the standard 5.7" C-C rod length. You also know that this is a late '68 to '69 era 302 piston - 67-early 68 used a different appearing dome arrangement, very distinctive, you can tell at a glance what years they fit. Early pistons were also press-fit pins rather than the floating pin arrangements for the later (2nd design) pistons like you see here.

Regards,
Steve
