1970 lt1 deuce pistons

[madden]

i understand boring a block as i have several drag cars that i built engines for

my issue was i did not know if the LT1 came with 4.00 inch bore OR 4.030 bore due to the fact i had read some many different things on this site and others

i felt that it could have been very possible for don yenko to bore the yenko engines out for several reasons

thanks everyone for the answers

i will continue looking now for LT1 4.00" OD forged GM TRW pistons

thanks again
regards
