I agree with the others, If your engine is in good condition, don't bother with the 4.0L or the multiport efi. I personally would use the howell. We've had one or two list members over the years that installed Howell/GM TBI units and once they were up and running they worked well from what I remember. I didn't notice anywhere what year Eagle you have. The only thing I would consider changing out would be the plastic valve cover if it happens to have one. If the engine dies or is troublesome,leaking, etc; I'd consider getting a 4.0L at that point. Or if you tow, haul a lot of people, stuff, then I'd consider building a stroker. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 -------------- Original message ---------------------- From: Russell Neyhart <rtneyhart@xxxxxxxxxxxxx> > Good Morning, > > I'm looking for some parts and advice.
