I'm getting ready for a complete rebuild of my 390 and have learned a lot on this site.I just want to check and see if i have everything straight on my list of things i need. This motor is going in a 1976 high boy and will be used for pulling a trailer with a tractor and crusing around ..
why the performer rpm intake???? It has almost zero gain over a stock 4bbl cast iron manifold other than weight. Consider a M57HV and oiling mods to the engine.
I was going on what i have read on my searches on this site. it seems to be a popular intake and this is my first rebuild thats why i was asking for advice on my choices. what are the advantages of m57hv???
