	This has been most entertaining and yes I will go hit the books as I do want to learn. Back in the day (as I class myself as a young old fart) I ran a blown BBC sedan and my favorite combo was a 427 steel crank in a truck block with 4.375 bore and 10.5 pistons with a 1471 fuel blower and rectangle iron heads.made about 1200 hp on a good day. Cheers: auschris ps: so the main difference between a L78 and a L88 was 7/16 rods and aluminum heads  |
