The Renix head is low rise like the 258, but high compression like the 4.0L HO. Kinda doubt you could make the HO manifold fit, and you would not get the same benefit from a HO head that a 258 would.Cecil14 wrote:I know they changed the head from Renix to HO, but I'm not sure if it's enough that you can't make an HO manifold fit or not. You could always swap heads, but if you've got any kind of investment into your Renix head or a questionably worn bottom end that's probably not the best plan.
I've got my wiring notes around here somewhere...they're not spectacular, but anyone that wants them is more than welcome to em. I do plan on going back through my wiring here real soon. I've got some other problems I need to address, and I want to upgrade some things as well. If I can get the motivation together, I want to draw out my wiring in Autocad. Maybe with a few beers...

Rather than convert to Mopar/Bosch(?) MPI, you can junk the Renix electronics and run a Megasquirt system. http://www.msextra.com/forums/viewtopic ... 31&t=49969 Been done before - search the net and find plenty of references.
