Re: Have been offered an original 69 L78 motor....
O.k. so here are some more of the details.....
Non original stuff: - Cam - Water pump - Fan - Carb - Distributor - manifolds - Carb (does have a 3310 780 on it though) - oil pan Other notables: - 163 intake has had plenum divider cut down. Date code is not verified. - Heads are unported and stock. Do you think this is a worthwhile trade for my 600hp 454? His L78 has roughly 5k miles and does not burn any oil, never raced etc... What I would do to it is: - Add manifolds - Crane blueprint L78 cam - Use my valve covers, deep groove L78 pulleys. thoughts / comments welcome...

Re: Have been offered an original 69 L78 motor....
Well, since the body job, I am retiring it from racing on slicks and truth be told would really only consider running it on bias plys from here on in. Realistically though, I would doubt I do this more than once a year if even at all.
Thanks for the feedback.

Re: Have been offered an original 69 L78 motor....
It sounds like the L-78 is about a $5-6000 engine maybe a little more. Is your current 454 worth that?

Re: Have been offered an original 69 L78 motor....
I know this might sound stupid but isnt JH a camaro code? If i was doing an L78 conversion on my car I would want the correct JD code. Just a thought.

Re: Have been offered an original 69 L78 motor....
I would opt for the devil you know. Also do you currently have hydraulic lifters? You'll need to adjust those solids once in a while..
