what is your thoughts on the conversion? Do you have any experience? Yay or nay? Are they worth it. Without knowing anything about them to me it falls into the same category and converting to electronic ignition. Everyone has their opinion.
I put an older Holley unit on an L48 years ago and I was happy with it until I LS swapped it. If you look over in the HiPo forum there has been a lot of churn on them.
I personally like the conversions because I have an intense, burning hatred of carbs. I will agree with many that a TBI conversion is a half-measure. To really get the full benefit of fuel injection you need to go to an MPFI system. The TBI addresses a lof of the issues that arise when a vehicle sits for a long time between runs.
It also gives more flexibility for tuning because there are more knobs to turn. Whether that is a pro or a con is up to you. I am probably going to put one on my 58, if that tells you anything.
