400ci Bigblocks are awesome. 4.34" bore (like a .020" over 440) and a 383 stroke......stock.
all are 8.5:1 smog engines....and likewise come with 452' casting heads with hardened valveseats.
btw
I have a 9077S thermoquad off a running good 400 I would sell/trade. I changed to a edelbrock for tuning reasons.
If anyone wants it PM me....I am sure we can reach an agreement.
