Would you all recommend this for my 1991 L98 or do you all think it would be a waste of my money?
Why waste your money on the coolant bypass piece when you can do it for free. Look at my engine pictures. All you have to do is run a heater hose from the metal line on the pass. side frame rail, over the AC compressor, and onto the heater hose port in the front of the intake. And before you ask, no there are not any hood clearance issues.we dyno tested those before....THEY ARE A TOTAL WASTE OF TIME AND CASH!!!
if you must TINKER.....heres a cheap mod that works
BTW the throttle body air foils DO give you about 1-2 hp if your determined to waste $40
BUT porting your plenum and runner entrances gives you more and costs less
