You will also notice in the shot of the rear of the 302..the lower manifold surface is the same as the top of the bellhousing flange just like the front is.
Since it is apparently a bone stock engine any one of several numbers that are easily visible would also pinpoint what it is...the intake manifold has #s cast on top...the 351W would be a minimum of a C9 casting, the dist. has a number stamped on it that is easily visible, the carb has a tag, but it could have been changed( though it doesn't appear to) so there are some easy access #s that several members could taranslate for you.
Yes, as far as I know the 5.0 HO had that order and/or all 302's after '82 I think had the same firing order but im not sure..? I will gather all numbers you mentioned tomorrow for anyone to confirm it being a 351.. Thanks
