I have a 91 blazer with all the bolt-ons completed i.e headers, exhaust, underdrive pullyes, hypertech power chip, hypertech thermostat, cold air intake.

My question, would adding a new Holley TBIand an Edelbrock intake manifold begood?Does anyone have these add-ons? Motor has 195,000 miles on it with no oil leaks and doesn't burn oil.Just wantingto add more horsepower.Ihave plansto overhaul the engine withoversized pistons, new camshaft etc.. butnot right now.

 

Airflow will always help. To get the maximum benefit from everything that you have done to date, I would recommend a new cam and possibly a set of higher ratio roller rockers.

sorry to hijack the thread but putting the chip in, how much power gain did you get? was it noticable... i've been thinking about buying one for my 89 jimmy... want some info before i do it
