Re: 4.7L vs. 4.7 HO - differences?
Non-HO...supposedly some of the later gen 1s got some different parts but no reliable evidence.
I may be porting a Gen 1 manifold soon, will be interesting to see if it ends up being a cheaper alternative to a 08+ manifold. The 08+ is a beautiful piece but is more expensive than most want to spend.
Due to my workload, please do not PM me as I do not regularly check my PMs. Thank you :)
