Holley Terminator X or MPFI for 489 BB
So I am going to be ordering parts now for a winter install. Will have professionally done as i don’t really have the know how or time.
I have settled on Holley products and looking between two mentioned.
It’s putting out dyno’d 383 to rear wheels. Going to add a set of Brodix or AFR heads.
I have been looking at a torque storm SC but not sure of quality but may or may not add a power adder.
Pretty sure keep naturally aspirated, no more than 600ish HP but who knows.
I know the terminator will work but if is the MPFI better?
Performance?
Reliability (most important)?
Can Terminator ECU be upgraded to MPFI down road?
Again most likely NA with 600 HP will be most likely…. At least for next 5 years…
Did a lot of digging but most info I could find on here and the interwebs were 5-25 years old. Would like some current info
Thanks in advanced,
